The Best Convertible Car Seats


GearLab spends tens of thousands of dollars crash testing car seats at the same certified testing lab the US Government uses for its safety certification testing. We bought and crash-tested the top 22 convertible seats in this update to find the best. We conduct side-by-side tests of each convertible car seat over several months to determine the best in metrics like crash test performance, installation, ease of use, quality, and more.

Our favorite seat that is best for most families is the Graco 4Ever DLX. This reasonably priced car seat has one of the best crash test analysis scores, is easy to install, and super easy to use.

If your budget is a little tighter, but you worry about crash test results, the Graco Extend2Fit 3 in 1 costs less than the 4Ever but provides a similar crash test result. While somewhat harder to install, it offers a comfy seating area and quality materials.

We've tested more than 200 car seats, including 52 convertible seats. If you are not sure which kind of car seat is right for you, check out our Best Car Seat Review for more details. If your kid is graduating from a convertible seat, our best booster seat review is perfect for the next stage in safety car seats. Not ready for a convertible? Infant car seats is where you should look for the best options designed with little bodies in mind.

Editor's Note: This convertible car seat review was updated on November 27, 2024, with 4 brand-new additions, including options from Britax, Chicco, and Graco.

The Graco 4Ever DLX is a great all-around seat suitable for most families, regardless of your car seat goals. We love the better crash test sensor results and believe the 4Ever potentially offers an additional margin of protection based on our analysis of the results. In our tests, it had one of the lowest G forces recorded in the chest clip sensor (lower is better) and one of the best-combined results for the HIC and chest clip results. The 4Ever is lighter than the average convertible seat, weighing 21.8 lbs in our tests, and relatively short from front to back (25.3 inches), making it a contender if you have a smaller car or longer legs. This seat is good-looking, easy to use, and offered straightforward installation during testing. Plus, it comes at a reasonable price, well below the average for the group.

While the 4Ever is one of the best seats and a tester favorite, it isn't very narrow, and three across in one row might be harder. We measured it 19.3 inches at its widest point, it is almost a full inch wider than the Graco FlimFit 3-in-1. The SlimFit has similar scores in most metrics, including crash test analysis, with the benefit of a lower price. If you want something that provides more comfort and quality but is otherwise comparable to the 4Ever, the Graco Extend2Fit 3 in 1 can save you money with very similar performance and features. Overall, the 4Ever is an impressive top scorer that offers a lot and will make most families happy. As one tester said, “This is hands down the seat I'd choose for my kid.”

REASONS TO AVOID

The Graco Extend2Fit 3 in 1 is an impressive convertible seat in this lineup. It features push-style LATCH connectors that were easy-to-use during testing compared to the competition we tested. The Extend2Fit performed well in our commissioned crash tests, earning one of the highest analysis scores in our lineup of options thanks in part to one of the lowest sensor readings for the HIC sensor. It offers a comfortable riding experience for little ones with ample padding and a nap-worthy headrest that includes a non-rethread harness height adjustment with 10 height options. Taller kiddos will appreciate the leg extension that offers more legroom than a standard seat. One kid tester remarked, “I could really nap in this seat.

The Extend2Fit offers better crash test results than our budget-friendly option, and with sales, you can often find it for a cheaper price than other award winners in this lineup. It isn't as easy to install using the vehicle belt, which you'll have to do at some point. While not super challenging, if this is going to be your main installation type, the Graco 4Ever DLX might be a better choice. It also is not narrow, taking after the 4Ever, making the Graco SlimFit 3-in-1 a better Graco for limited space. Interestingly, the Graco Turn2Me is the narrowest Graco in the bunch, and it is a cool rotating seat with impressive crash test analysis results. Overall, the Extend2Fit is an excellent option that will work well for most families but is a real contender for those concerned with staying rear-facing longer and crash test results.

Seat Bottom Width: 18 in | Rear-facing Passenger Weight Limit: 40 lbs
REASONS TO BUY
360 rotation
Better crash test results
Easy belt install
REASONS TO AVOID
Lots of sticker clutter
Harder LATCH

The Graco Turn2Me 3-in-1 is a really cool rotating seat from Graco. As we see more of these on the market, we are getting a clearer idea of who is doing this well, and the Turn2Me is getting much of this style right. Turn2Me earned one of the highest crash test analysis scores in our tests. This option had one of the lowest HIC results we've ever seen (like golf, lower is better) and a combined chest clip and HIC sensor results to come out on top. The vehicle belt installation was the easiest for this seat, with a clear belt pathway and visibility to the back panel and belt lock-off compared to rear-facing. This option is one of the smallest and lightest rotating seats we've tested, with a weight of 26.1 lbs, a width of only 18.4 inches, and a rear-facing length of 27.3 inches in our tests. The weight and width are average for the group but still small for this kind of seat, and the length is actually below the average.

The Turn2Me shell has a lot going on, and there are so many stickers, warnings, and installation help that it ruins this seat's overall look and feel. While we understand some warnings are necessary, and installation help is appreciated, options like the Nuna Rava keep the stickers closer to the base, creating an overall more appealing look. The Turn2Me also offers lackluster padding that is adequate but nothing to write home about. The headrest area is better than deep in the seat bottom, but the back is very thin and disappointing. Alternatively, the Chicco Fit360 has better padding overall and softer fabric. These are minor trifles, really, and we are hard-pressed to find a reason to dismiss the Turn2Me if a rotating seat is your primary objective. As one tester said, “With crash test analysis this good, the Turn2Me rotating seat is a game changer.

REASONS TO AVOID
Low quality
No real padding

The Evenflo Tribute 5 is one of the least expensive seats in this review. However, that is not enough for any product to win an award. The Tribute fills a niche we think will appeal to many parents for different reasons. It is the cheapest seat in our review but it earned one of the top crash test analysis results! We love safety and think it offers an additional margin of safety over lower-scoring options, so we gave it an award despite its lackluster performance. With some of the lowest HIC and chest clip's sensor readings in the group (low is good), it stood out in a crowd of much more expensive options, proving a higher price doesn't always equate to a safer seat. As our in-house tester said, “The crash tests alone make this car seat one I'd recommend.” The Evenflo is also the lightest seat in the group, with a measured weight of only 9.4 lbs, making it ideal for travel or any use where carrying or lifting it will be required. If your budget is tight and safety is key, the Tribute is an excellent seat to consider.

The Tribute is hard to install, so much so that if you can afford something like the Graco SlimFit 3-in-1, we think it is worth the extra money for good crash test results and more straightforward installation performance. While more than twice the price of the Tribute, if you can swing it, we think it is worth it. It also isn't the easiest to use, with a rethread harness height adjustment and bare-bones design. The Graco 4Ever DLX excels for ease of use, and while more expensive than both the SlimFit and Tribute, it would be our preferred seat if your budget can stretch. However, if you have the tightest budget, travel frequently, or need a secondary seat that doesn't need to be installed very often, we think having a seat like the Tribute on hand is useful.

The Nuna RAVA is a very high-end convertible car seat with deep comfort padding, super soft fabric, and a sleek look with quality construction and impressive attention to detail compared to the competition in our tests. The Nuna offers top performance for comfort and quality and is easy to install, no matter which option you prefer, thanks to an easy-to-use lock-off that creates a stable final installation. We like that it is the easiest option to use with a smooth-moving harness height assembly that offers 10 positions. It has 10 recline positions and 2 crotch strap positions, so it is a comfortable fit for most kids. The Rava also has some of the best crash test analyses, with some of the lowest G forces in the group recorded for the HIC sensor and chest clip sensor. These results indicate a potential margin of safety over the average seat in this review.

The Nuna is expensive, making it a possible no-go if your budget is limited. For about half the price, you can get the Graco Extend2Fit 3 in 1, which has the same crash test analysis score and is lighter than the Rava. The Rava is also heavy, so it isn't the best choice for traveling or carpooling, as we believe most parents won't want to carry it for very long. One tester said, “I wouldn't want to carry this big lug through an airport.” If you want something less expensive or better crash test results, the Graco 4Ever DLX is a great choice. While it lacks some of the quality and comfort of the Nuna, it has one of the best crash test results in the group and costs significantly less. If you long for something even easier to carry with good crash test results, the Graco SlimFit 3-in-1 is a good pick that saves even more money over the Gracos already mentioned. Overall, the Nuna is a quality seat with impressive scores in most metrics, and for families where budget is less of a concern and ease of use is number one, the Nuna is one for your list of contenders, as it brings the full package to the table.

The Chicco Fit 360 is a good-looking rotating seat that only needs to be installed once and can still be used rear or forward-facing. In our tests, this option is one of the easiest to install, no matter which method you choose, making it a shoo-in for those with installation anxiety. As our central tester said, “This would be the seat I chose for my kid based on installation alone; nothing could be easier.” We also felt the Chicco was easy to use during testing with a harness height adjustment that has 15 possible positions over a 10-inch range. It is non-rethread, so you can make adjustments on the fly with a toddler in the seat. During testing, we were also impressed with the padding and fabric used on the Fit360. The padding is thicker in the back and bottom than many competitors, and it looks as comfy as a La-Z-Boy recliner.

The Fit 360 is heavy and long compared to the competition, even the rotating seats. If space is limited and rotation is a must, we think the Graco Turn2Me could be a literal better fit with a length of only 27.3 inches compared to the Fit360's 32.3 inches. The Graco is also only 26.1 lbs compared to the Chicco's 32.4 lbs. The Fit360 is also on the spendy side, and while not as expensive as the rotating Cybex Sirona S, it can't hold a candle to the Turn2Me that can save you about $50 on average, and sports one of the highest crash test analysis scores. The Chicco has slightly below-average crash test analysis results that are neither a pro nor a con in our minds, as it has passed the federal standard and is considered safe. We think the Fit360 is a cool seat and the perfect choice for those worried about the installation. Since improper installation increases the risk of injury or death in an accident, this alone could be a reason to choose the Chicco over harder-to-install competitors despite the boring crash test results.

The Graco SlimFit 3-in-1 is a great seat with better crash test analysis results and a reasonable price tag. The SlimFit was easy to install using LATCH, has better push-style connectors, and didn't require towels in our tests. It is significantly lighter than the competition, with a measured weight of 18.5 lbs, which is 7 lbs lighter than the average seat we tested. The SlimFit has a non-rethread harness headrest adjustment with 10 possible positions and a crotch strap with 3 positions, creating enough variation for most kids. The assembly was easy to adjust in our tests, and the headrest moved smoothly up and down even with a child in the seat. We think it is easy to use and provides enough features for comfort that you won't get complaints from toddler passengers on longer rides.

All of the Graco seats performed well and were almost in a class of their own in this review. If you want slightly better crash test scores than the SlimFit or a better overall result, then the Graco 4Ever is one to consider. If you hope for something similar to the SlimFit but want more for comfort or quality, then the Graco Extend2Fit 3 in 1 might be a better fit. More than one tester remarked, “This is a super comfy seat.” If you hope to put three car seats in a row and the average width of the SlimFit just won't do, the Britax Poplar S measures only 17 inches at its widest point, and while not an award winner, it performed valiantly in most metrics, including an average crash test analysis result. While belt installation for the SlimFit could be easier, the LATCH installation was about as easy as it comes. If you want an easy-to-install using the vehicle belt option, the Graco Turn2Me is a standout for straightforward belt installation without compromising on crash test analysis results. We think you'll be pleased no matter which seat you go for, but if you want a high scorer with a lower price, we believe the SlimFit is the best fit.

How We Test Convertible Car Seats


We take convertible car seat testing very seriously because the stakes are so high. The National Highway Traffic Safety Administration (NHTSA) states that “car crashes are a leading cause of death for children ages 1 to 13.

We tested each and every convertible car seat in this review by commissioning crash testing from MGA Research so we can compare the results apples-to-apples. The Nuna Revv is shown here and did not perform as well as many competitors.
Credit: GearLab & MGA Research

Our testing process begins with buying two units of each car seat. We send one to the same certified crash testing lab used by NHTSA for crash testing, and we share the crash testing results with you to help you make an informed decision. Our tests are somewhat faster than the federal guidelines to help differentiate between safe but average seats and those that might offer an additional margin of safety. We also use a more modern sled to better align with late-model vehicle seat designs. Then, we buy a second unit of each car seat to put through our rigorous hands-on testing process at GearLab. Combining unbiased crash testing and hands-on testing allows us to evaluate car seat performance from a safety and daily use perspective.

We tested each seat in multiple cars and some were harder than others to install.

Our convertible car seat testing is divided across six rating metrics:

  • Crash Tests (35% of overall score weighting)
  • Ease Of Installation - LATCH (20% weighting)
  • Ease Of Installation - Vehicle Belt (15% weighting)
  • Ease Of Use tests (15% weighting)
  • Comfort/Quality tests (10% weighting)
  • Weight/Size tests (5% weighting)

Over the last several years, we've purchased more than 100 convertible car seat models (two of each). We conduct a multi-point performance analysis to score and rank crash test results and other functional metrics like ease of use and installation (LATCH and belt). We've probably installed more car seats than anyone on the planet. Our testing includes multiple testers installing the best car seats in multiple vehicle types across all safety seat categories: convertible, boosters, and infant seats. We install them facing forward and facing back using the LATCH and vehicle belt.

Not all of the car seats passed the wiggle test for stable installation in our tests.

The convertible car seats are subjected to more than 45 individual tests to evaluate their performance. The most important rating is the crash test analysis score based on the crash test results from MGA, corresponding to 35% of the overall score. We use the head and chest sensor data recorded by the crash test dummies in each seat to reach our conclusions for this metric. Our reviews also rely on intense product research and observations from multiple testers to compare each product side-by-side.

Infant car seats are designed with little bodies in mind and are our preferred safety seats for younger babies.
Credit: Abriah Wofford

We suggest you keep your baby in their infant car seat until they are 9-12 months old or as their height starts to push the infant seat's maximum length (always rely on the manufacturer's limitations of your infant seat to guide you). You should check weight capacity, too, but more often than not, the height limit will force the switch to a convertible seat.

If you are looking for a convertible car seat, then your baby is in the age range when many parents are also thinking about choosing the best baby backpack carrier to make it easier to walk long distances. If you live in a bike-friendly town, a bike trailer can also be a fun addition.

Why Trust GearLab


Our in-house convertible car seat test protocol development was led by Certified Passenger Safety Technician, Bob Wofford. Bob helped create our original in-house testing protocol. We also consulted with the National Highway Traffic Safety Administration (NHTSA) experts about their protocol and crash test results. Last but not least, we consulted and contracted with MGA Research, the same national testing facility that has the compliance contract for FMVSS 213 assessing the safety of car seat in the US. Jessica Riconscente also contributed with hands-on testing. As a Senior Review Analyst, she led the charge for all car seat updates, testing, and installation for more than 60 seats across categories. Wendy Schmitz is a mother of 2 and has researched and written about car seats for over 10 years. Our panel of experts also includes Dr. Juliet Spurrier is a board-certified pediatrician , mother, and founder of BabyGearLab with a background in urgent pediatric care.

Rear-Facing Until at Least Age 2
Experts agree that children should remain rear-facing until at least two years old. The American Academy of Pediatrics (AAP) and NHTSA recommend keeping your baby rear-facing as long as your chosen car seat allows, and at least until age 2. The Graco Extend2Fit is a top-scoring option that can remain rear-facing until the passenger weighs 50 lbs, but there are many others (see our specs table for details). So, no matter how tempted you are to turn your little one around, we encourage you not to so you can retain the potential safety bump facing backward offers.


What's the Best Value?


This group has budget-friendly options with winners and lower-priced seats to meet your needs and safety goals. It was refreshing to see so many reasonably priced options perform so well with standout crash test analysis results. Our Editor's Choice winner is a great value, even if it is somewhat more expensive than some, as it is still about three hundred dollars less than the most expensive selections.

The Graco SlimFit is a similar option to the Graco 4Ever, but it has a more budget-friendly price.

The Graco 4Ever DXL (above left) is an impressive all-around seat we think parents will appreciate. However, if this is a little out of budget, the Graco SlimFit 3-in-1 (above right) is a budget-savvy choice with a similar test result profile and a lower list price. If it is a rotating seat you want, the Graco Turn2Me had impressive crash test results, and while it is more expensive than the other Gracos, it is one of the least expensive rotating seats in the review. Last, if your budget is uber-tight and you need the best crash test results for the lowest price, the Evenflo Tribute is tough to beat with a price almost anyone can afford and a crash test result that few seats bested.

The Evenflo Gold Revolve did not perform as well as most competitors, with some of the lowest crash test results in the test group based on sensor data collected by MGA Research.

Crash Test Performance


BabyGearLab contracts with the same crash test facility that NHTSA uses to perform our convertible seat crash tests. We purchase two of each seat and send one to MGA, where we pay for them to complete crash tests. MGA tests the seats using a faster speed and a slightly firmer sled than the FMVSS 213 safety standard. We chose this on purpose to mimic late-model vehicles better and to see if faster speeds helped differentiate the seats from one another. All seats in this review are assumed to have passed the federal guidelines and should be considered safe. Based on test results, those we identify as better than average are options that potentially offer an additional margin of safety over the average seat.

After receiving the crash test data we commission, we analyze the sensor data from each car seat's crash dummy to determine how it compares to the competition.

More Money Doesn't Equal Safer
While you might think a more expensive seat will be safer, according to our test results, this isn't necessarily true. The Evenflo Gold Revolve360 and the Nuna Revv are examples. The Evenflo Revolve360 and the Nuna Revv have prices well over the average but did not perform as well in crash tests as similar contenders. Alternatively, the cheapest seat in the group, the Evenflo Tribute 5 had one of the best crash test analysis scores, proving that price isn't indicative of potential safety. Other examples are any of the Graco options in this review. All performed at or near the top for crash testing but have prices below the average.

So, what is the most critical information from crash impact tests when analyzing results?

  • The risk of head injury related to the HIC sensor result
  • The risk of chest injury related to the chest clip (g clip) sensor result

Where do we get our crash test data?
We pay MGA to perform crash tests on each seat in our review. We purchase and send the seats directly to MGA, and they supply us with the sensor data after testing is complete. We do not use data from other companies, such as Consumer Reports, as they perform different tests, and any information they provide does not allow for a side-by-side comparison of test results.

An analysis of auto crash injuries for children shows that head and chest injuries are the two most significant risks of fatal or severe injuries. That is why we use sensor data from these locations.

All of the Products We Tested Provide a Basic, Safe Level of Protection
All of the convertible car seats we test are assumed to have passed the federal minimum safety standards. Therefore, every seat has at least the basic level of crash safety protection required by US Federal law. Our primary focus for crash test scores is identifying seats whose crash test performance exceeds the federal requirements by performing well in our hotter tests. These car seats can be considered as providing a potential additional level of protection based on the data from its crash test sensors.

The Cybex Eternis features a side-impact feature that is supposed to aid in some way during a side-impact collision. While we love safety, given the lack of test data or industry-standard side-impact testing, it is hard to say what, if anything, this innovation brings to the safety table.
Credit: Abriah Wofford

Additional Safety Features


Some seats have additional features that manufacturers claim will improve the seat's safety. Our crash test score analysis did not consider these features or claims. Because manufacturers do not publish comparison test data to analyze, it is impossible to determine their efficacy. We understand parents are curious about side impact protection (SIP) or an anti-rebound bar (ARB), and these features could factor into your decision-making process. Still, we encourage you to proceed cautiously when deciding based solely on these features. There is no way to tell what each manufacturer means when they use terminology that lacks an agreed-upon meaning (like SIP). This lack of information makes it impossible to compare seats with similar-sounding claims, especially without a universally agreed-upon language to describe what the claims genuinely mean.

We can confirm that our crash test results indicate that anti-rebound bars often, but not always, improve the crash test dummy sensors results compared to not using the anti-rebound bar. We like them as a safety feature, but we feel actual crash testing data is more critical than stated features or claims.

Safety Reminder
How well a seat performs in a crash test environment means little if you don't install the seat according to the manufacturer's instructions. Poor installation or a poorly fitted harness can potentially result in injury or death in an accident.

Best Seats Based on Crash Test Analysis


We rated each seat compared to the competition using crash test report analysis. The scoring helps quantify the convertible car seats that offer a potential additional margin of protection, in our opinion, over and above the basic level of protection found in all seats.

The Turn2Me earned some of the best crash test analysis results in the group.

The Graco 4Ever DLX earned our best crash test rating thanks to excellent Chest Clip (g) and HIC scores. The Graco Turn2Me had even lower (better) HIC sensor results and a similar chest clip result, making it a crash test stand out for rotating seats. The Evenflo Tribute 5, Graco Extend2Fit 3 in 1, Nuna Rava, and Graco SlimFit 3-in-1 have similar analysis results just slightly lower than the 4Ever and Turn2Me. Overall, we were really impressed with the Graco seats in this review when it came to crash test analysis. The Chicco NextFit Zip and the Baby Jogger City Turn are just below these results and still rank above average.

The Revolve is one of the easiest options to install using LATCH, but its lower crash test analysis results hurt its overall score.

Ease of Install Using LATCH


Studies show that more than 7 out of 10 car seats are installed incorrectly or the harness is not fitted correctly . As a result of these statistics, we feel ease of installation and ease of use are critical metrics when selecting a car safety seat. Both can potentially impact overall safety, and we take these metrics very seriously.


The Lower Anchors and Tethers for Children (LATCH) installation method should make it easier to install car seats correctly with fewer opportunities to make mistakes. For this reason, we recommend using the LATCH method whenever possible to increase the chances of installing a seat correctly. Nearly all convertible car seats have the LATCH connectors, and most vehicles manufactured after September 1, 2002, offer the anchors on the left and right sides of the back seat. So, the good news is you should be able to utilize the LATCH method until your child outgrows the LATCH connectors' weight limit (please see your safety seat user manual).

Installing any seat using the LATCH system should be straightforward and easier than the belt, while our tests reveal this is not always the case, the Extend2Fit is one of the easier options to install using LATCH.
Credit: Abriah Wofford

Our tests determined that some seats are easier to install using LATCH instead of the vehicle belt. However, surprisingly, many options are easier to install using the vehicle belt not the LATCH. The main problem? Some testers struggle to tighten the LATCH straps to properly secure the convertible car seat to the vehicle.

Hook-style LATCH connectors, like the one shown here on the Britax One4Life, are harder to use than push-style connectors, especially when trying to remove them from the car anchor points.

There are three main types of LATCH connectors: push-style (above left), hook-style (above right), and rigid LATCH (video below). We typically see the hook-style connectors on less expensive seats like the Evenflo Tribute 5, and were surprised to find them on some of the more expensive options like the Britax lineup. They tend to be harder to remove as you have to loosen the LATCH strap to push the clip forward to unhook it from the anchor point. Alternatively, push connectors have a button that releases the connector, much like a seatbelt.

The Clek Foonf offers a rigid LATCH connection in the forward-facing configuration only.

One of the most straightforward LATCH connection types is the rigid LATCH, like those seen on the forward-facing Clek Foonf. This design is virtually foolproof, with not much to do other than make the connection and slide the seat back.

Best Seats For LATCH Installation


Top-performing seats for LATCH installation include those with push-style connectors, easy-to-pull straps, and usually lock-off mechanisms. The easiest seat to install using LATCH is the Chicco Fit360. This seat has a one-time installation base with easy-to-use LATCH connectors and a locking mechanism that snugs the seat into a very stable final fit that is no-muss, no-fuss. Coming in close behind are the Nuna Revv, Evenflo Gold Revolve360, and the Cybex Sirona S. Other h higher ranking seats include the Baby Jogger City Turn, Nuna RAVA, Graco 4Ever DLX, Graco SlimFit 3-in-1, Graco Extend2Fit 3 in 1, and the Britax Poplar S. The hardest to install using LATCH are the Safety 1st Grow and Go All-in-One, Diono Radian 3RXT Safe+, Clek Fllo, and the Maxi-Cosi Pria All-in-One.

Center Seat Issues

The safest spot to install your car seat is in the center of the vehicle's rear seatstudies of injury data show a 43% lower risk of injury if the car seat is in the center of the back seat. Combine this information with the knowledge that LATCH connectors should be the easiest and safest way to install a car seat. What's the problem? Most vehicles do not offer LATCH anchors in the center location. Even if the inner LATCH anchors from the side positions are close enough, most vehicle and seat manuals do not allow the use of these LATCH anchors for the center position installation.

What is the best alternative if your vehicle doesn't allow the LATCH method in the center? Should you use the center seat with a vehicle belt or the LATCH system on a side seat? One of the most critical aspects of seat installation is ensuring the car seat is securely and tightly anchored to the vehicle.

The questions on center seat installation include:
  1. Should you install the seat with the vehicle belt?
  1. Is the seat as secure when anchored to the center seat with a vehicle belt as it is in the side position using LATCH?

Using the vehicle belt to install a car seat is a perfectly safe and acceptable installation method (and potentially the only possibility for center seats), assuming you can ensure that the installation is secure and tight. Use the center seat if you can get a tight fit (and we did with many seats in our tests). However, if obtaining a secure fit in the center seat is challenging, you should move your safety seat to the side seat location. It is far more critical that the car seat installation is correct than the installed seat's actual location. If you have two children, you may not have a choice as many cars don't have enough room for a side and center installation simultaneously, and/or little ones often fight if they can reach each other. Suppose your vehicle doesn't offer LATCH anchors for the center seat, but you prefer center seat installation. In that case, our tests on ease of installation with a vehicle belt can help you identify the easier options to install using the vehicle belt. Also, you can locate an installation professional for assistance using the vehicle belt if you feel unsure.

Some SUVs, trucks, and wagons have a center seat belt in the car's ceiling.

Ease of Install — Vehicle Belt


No matter how or where you hope to install your new car seat, you must install it using the vehicle belt at some point, as LATCH connectors have weight restrictions that most children will outgrow before they outgrow their convertible car seat. Also, many center seats don't have LATCH anchors, even though it is the safest location for seat installation. Most LATCH connections use weight limits of about 40 - 50 lbs of child weight before the seat requires installation using the vehicle belt only. Given that many of the products have a weight limit of 50-80 lbs, it is clear that most children will utilize the vehicle belt at some point.


Don't despair! We will tell you which seats are the easiest to install using the vehicle belt and provide information on the correct installation and where to get help if you are unsure about anything or if something doesn't seem right.

The Benefit of the Seat Belt Lock-Off


Some seats are easier to install using a seat belt than competitors, and most of these seats have a trick by way of a belt lock-off located on the seat. This feature is so helpful; it is a game-changer for installing seats with a vehicle belt, and we believe you'll feel significantly more comfortable installing a seat using the belt if it has one of these nifty lock-offs.

In this review, several seats have a belt lock-off located on the seat. Interestingly, most of these seats ranked higher overall and have higher installation scores using a vehicle belt. The Chicco Fit360, Evenflo Gold Revolve360, Nuna RAVA, and the Britax Poplar S scored the highest for belt installation and each has a useful belt lock-off.

Coincidence? We think not.

Some lock-offs work a little better than others, but even those that are challenging, still provide a more secure feeling installation in our tests than seats without a lock-off. We found that options with a lock-off were as secure when installed with a belt as with the LATCH (some even more so). This fact can be a relief when you need to install the seat with a belt, which is highly likely given the weight limitations of LATCH systems.

The seats lacking a lock-off typically didn't perform as well and included the Diono Radian 3RXT Safe+, Peg Perego Primo Viaggio Convertible, Safety 1st Grow and Go All-in-One, and the Maxi-Cosi Pria All-in-One. Interestingly, the Clek Foonf and the Clek Fllo both have lock-offs but were challenging to install despite this and didn't score well for this installation method.

Ease of Use


Convertible car seats have similar designs with few obvious differences outside of cosmetics. However, in reality, the options diverge in ease of use, with some being significantly easier to use than others, thanks to extra features or better functionality of features like buckles. It is clear that some manufacturers spend more time on thoughtful and useful design choices to make everyday life easier.

The Ease of Use metric includes the functionality of standard features, including harness adjustment and chest clips, ease of tightening or loosening the harness, fabric cover removal for cleaning, and more. If your chosen option is challenging, you may inadvertently avoid using it as the manufacturer advised, or you could become chronically frustrated.

Buckles and Chest Clips


The buckles and chest clips in this group are largely average. While some have prongs that pop out somewhat independently, and others have chest clips that slide apart smoother, none were that challenging or impossible to use. The Cybex Sirona S does have a smart chest clip that provides alerts and information about car temperature and if a child has been left behind. It works via Bluetooth with an app you download on your phone. The Sirona and the Nuna RAVA are two of the best in the group.

Harness Tightening and Loosening


Each seat has a harness-tightening strap and a harness-release button to loosen the straps and help your child remove the harness. Some of these were harder to pull, and the buttons varied in style and ease of use. The Graco 4Ever DLX and the Chicco Fit360 have some of the group's best tightening and release mechanisms. The Safety 1st Grow and Go All-in-One was rated poorly.

Adjusting the Harness


There are primarily two methods for adjusting the harness height on convertible car seats. The simplest method is a non-rethread style that involves moving the headrest/harness shoulder strap assembly up and down (video above). The more intricate design includes removing the shoulder straps from a splitter plate on the back and physically moving the straps from one slot height on the seatback to thread them through different slots. While this method isn't particularly hard or frustrating, it takes more time and requires you to remove your child from the seat for access, and if the car seat is forward-facing, you may need to remove the convertible seat from the car to reach the seat splitter plate. There is more room for possible error or avoidance of change with this method. Alternatively, the non-rethread method adjusts quickly with your little one in the seat as soon as you notice a need.

We prefer the non-rethread style because it is simple, and we think busy parents will be more likely to keep the harness adequately fitted if they can accomplish this quickly without removing their child from the seat. We worry parents will put off adjusting the harness with the rethread style when needed because it requires an empty seat and more effort. Since injuries can occur when a harness isn't correctly adjusted to fit, we prefer non-rethread assemblies. The Chicco Fit360, Baby Jogger City Turn, and the Graco SlimFit 3-in-1 are the easiest options in the group to adjust. The Clek Fllo, Clek Foonf, Diono Radian 3RXT Safe+, and the Evenflo Tribute 5 all require rethreading of the straps. In our minds, this design is acceptable for an inexpensive option like the Tribute 5 but is less palatable on seats like the Cleks with a higher premium price.

The seats all have some kind of LATCH connector containments system ranging from a simple hook on the seat side to hidden compartments like this one on the UPPAbaby Knox.

LATCH Storage


LATCH storage is arguably less important for convertible seats than infant carriers since they do not impact installation or inhibit connection between the seat and base. However, it is still helpful if the straps aren't readily accessible to your child and can't contribute to potential injuries floating loose. Some options have designated pockets for LATCH clips, while the most common storage method includes attaching the clips to designated points on the shell. None of the options in this group have hard-to-use or access LATCH storage designs, and none stood out as significantly better than the competition.

Fabric Removal and Cleaning


Kids' car seats undergo significant messes and require regular cleaning (whether you like it or not). For this reason, we test how challenging it is to remove the fabric covers for washing. We prefer machine-washable covers that are easy to remove and replace. We like handwashing methods over spot cleaning only, but because there is a high potential for throwup, spit-up, and poopy blowouts, it is ideal to have a machine-washable cover you can remove quickly.

Most of the seats are some variation or combination of snaps, elastic loops, and tucking in of fabric. None are overly challenging, but certainly, some are better than others. The easiest to remove include the Evenflo Tribute 5, Peg Perego Primo Viaggio Convertible, and the Safety 1st Grow and Go All-in-One. The Clek seats don't have removable covers and are spot clean only. We suspect you'll likely require a steam cleaner for bigger messes. Probably the most straightforward and unique cover is on the Chicco NextFit Zip, which has a cover that zips all the way around for easy removal for machine washing. If your little one is prone to messes or you like things extraordinarily clean, then a zip-off cover might be a top priority. The Britax Poplar S wasn't necessarily difficult, but there are lots of connection points and little elastic loops that it took us over 17 minutes to put it back on after cleaning.

Overall Ease of Use


Ease of use can make or break your daily routine and is comprised of the components you are most likely to deal with day in and day out.


The easiest seat in the review to use is the Nuna Rava. Nuna seems to think of everything and understands a real parent will be using this seat, and they might even like us a little. The Cybex Sirona S is also easy to use with a chest clip we love. Close behind these two are the Chicco NextFit Zip, Graco 4Ever DLX, and the Chicco Fit360. The most challenging seats were the Evenflo Tribute 5, and the Maxi-Cosi Pria All-in-One. While we prefer a seat to be easy to use, we can almost forgive the Tribute since it has a price tag under a hundred dollars. The same cannot be said of the Maxi-Cosi.

Comfort/Quality


For comfort and quality, we review the materials and overall construction. We analyze the padding, fabric, and foam and how well they come together compared to the competition. We consider how each seat's design contributes to a baby's potential comfort, parent use, and durability.

All convertible car seats have similarities, like a plastic shell, impact foam, comfort padding, and a fabric cover. However, some provide thicker padding, softer or more durable fabric, or foam that doesn't off-gas. Because this is somewhat subjective, we compare the seats side-by-side and rank them.

Seat/Insert


While most babies and toddlers won't complain about comfort, some seats are uncomfortable. We look at things like the fabric and its softness, as well as padding and whether it is supportive. While many of the seats have thicker headrests, some lack suitable padding in the back and seat. The Nuna Revv is above average with nice microform and soft fabric. The Chicco Fit360 is a comfy seat little ones wanted to nap in. Alternatively, the Evenflo Tribute 5 has almost no padding and is just a thin cover.

Most infant inserts were just fluffy padding, and they didn't provide firm support. This is part of why we recommend using an infant car seat for babies and switching to a convertible seat when your baby reaches the upper limit of the infant seat. The Chicco Fit360 has one of our favorite infant inserts, with a firm base that sits deep in the seat and attaches to the crotch strap to help keep it in place. The Nuna Rava also provides a nice insert with a padded block that goes below the softer top to help prop up smaller bodies. Both the Clek Fllo and the Clek Foonf lack an infant insert and provide nothing for smaller passengers.

Shell


Our favorite car seat shells have easy-to-clean, self-contained exteriors with a minimal amount of stickers and clutter that create a sleek-looking seat. Our favorites include the Nuna seats, Chicco Fit360, and the UPPAbaby Knox. The lowest scoring shell is the Evenfloe Tribute 5 because it really is sort of a hollow-backed option that could be hard to keep clean and has sharper edges. While the Graco seats were better, they have a lot of stickers that prevent them from blending into the background and could be hard to keep clean.

Overall Comfort and Quality


The best seats for comfort and quality are the Cybex Sirona S, Evenflo Gold Revolve360, and Nuna Revv. These seats are followed closely by the Graco Extend2Fit 3 in 1, Nuna RAVA, Chicco Fit360and the UPPAbaby Knox. The Graco SlimFit 3-in-1 and the bayark also performed well here. The lowest for this metric is the Evenflo Tribute 5. Both Clek* seats also ranked low in this metric, but their results were related more to an uncomfortably hard seat and unforgiving dense foam than the quality or materials. Kid testers did not think anything about the Clek options was comfortable.

Weight


While the weight of a convertible seat is likely not as important as the carrier weight of an infant seat, it can be a consideration if you travel frequently or use public transportation and need to carry it. A relatively new phenomenon in the convertible seats is those that have a base and a seat that is separate. Most of these are of a rotating variety.


If your seat will remain in your car most of the time, then how much it weighs might be less of a concern. The Evenflo Tribute 5 at 9.4 lbs is the lightest option, while the heaviest is the Clek Foonf at almost 34 lbs. The average is closer to 25 lbs, with several top-scoring Graco seats coming in closer to 20 lbs.

Width Size


How wide a seat is could be important to you if you need to fit multiple people or car seats across a back row in your vehicle.


We also measured the widest point on each seat for comparison. The Clek options are the narrowest at 16.9 inches, and the widest are the Cybex Eternis S and the Evenflo Gold Revolve360, both at 19.6 inches. The Britax Poplar S is a respectable 17 inches and is probably the narrowest seat with a higher score, though we gave our top pick for narrow seat award to the Graco SlimFit 3-in-1 because it is under 19 inches, and it has better crash test analysis results than the Poplar S.

How to Pick the Best Convertible Car Seat


When making your selection of which convertible car seat is best for your child, we believe it should be viewed through a safety lens. Safety includes how easy it is to install, how easy it is to use features like the harness, and how well it performed during crash testing.

Installation Method


Each seat has two different installation methods, and at some point, you will likely use both as the LATCH method will become obsolete when your child reaches a certain weight (which varies per seat). However, they are all different in how easy they are to use with each method. The ability to install a car seat correctly can impact its overall ability to perform during an accident, so you want to pick one you feel confident you can install correctly for maximum safety.

How easy is it to use?


Being able to use the seat's features correctly can impact the passenger's safety. Studies show that injuries in an accident can be related to incorrectly adjusted harnesses or inappropriate use of other features. You want to find a seat that is easy to use and adjust whenever you put your child inside.

Crash Test Analysis


Once you have a few easy-to-install and use seats on your shortlist, we think the last step is crash test analysis. While crash test performance is important, studies indicate that a lot of injuries happen during real-world accidents due to incorrect installation or a poorly fitted harness. However, this doesn't mean you should ignore crash testing; the analysis results can provide valuable information to help you settle on the perfect seat.
