To help you pick the best convertible car seat, BabyGearLab 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. In this update, we bought and crash-tested the top 18 convertible seats available today 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. We collect the details you need to choose the right car seat for your needs and your wallet. We purchase two of each car seat we review, one for crash testing and one for in-house testing, so you can trust that our results are unbiased and honest.

We've tested more than 60 car seats including 31 convertible seats. If you are not sure which kind of car seat is right for you, check out our Best Car Seats Review to get the skinny. Ready for something suitable for bigger kids? Look at our booster seat review for the next stage in car safety.

Editor's Note: We updated this review on May 5, 2022, with an overview of pricing changes and new products. This followed an update in December 2021, with more detailed information on sub-testing within the highest weighted test metric of ease of use. We added two new car seats in November 2021.

The Graco Extend2Fit earned the highest result in the group for crash test analysis with a combined head and chest sensor result that beats the competition. This Graco also has excellent results for LATCH installation, which can translate to better safety as studies indicate that many real-world injuries are related to installation errors. These combined results mean the Extend2Fit may potentially provide an additional margin of protection over the competition in this review. This information makes it an excellent option for those who want top safety indicators. The Extend2Fit can also potentially stay rear-facing for longer than most of the competition (up to 50 lbs), creating an excellent combination of features that potentially translates to a safer riding experience.

The Graco Extend2Fit didn't offer the highest quality compared to the competition; it lacks the same level of comfort provided by competitors in its price range. However, the Graco Extend2Fit is an excellent option for anyone who wants the very best crash test results and finds value in the safety potential of a rear-facing seat.

The Britax Emblem is a quality convertible product with easy-to-use, non-rethread shoulder strap adjustment, a push-button LATCH, and better comfort padding and fabric. This option has impressive crash test results that indicate a higher potential margin of safety. It is also easier to use than most of the competition. The Emblem's overall look and feel are better than much of the competition, and its self-contained design translates to easy to clean and sharp looking.

The Britax Emblem has a manual LATCH strap, unlike the popular ClickTight models. This design means it requires increased effort to install by comparison. However, this shouldn't be a deal-breaker unless you have limitations that prevent strap pulling. We believe the Emblem is an impressive contender, sporting better crash test results with a reasonable price that includes easy-to-use features and a nice look and feel. Overall, the Emblem is an excellent choice and one we'd recommend to a friend.

The Evenflo Tribute LX is a dark horse compared to our usual selections for best value as it doesn't rank very high in the competition. So, why did it get an award? This convertible option earned the second best-combined crash test results in the competition we tested for this review and it has one of the lowest prices. This combination makes it a worthwhile contender for anyone on the tightest budget or potentially as a secondary or travel seat. The Evenflo has a price significantly lower than the other contenders, a machine washable cover, an easy-to-use vehicle belt pathway, and one of the nicest buckles we've seen in testing. This seat is also super lightweight at around 9 lbs and narrow at only 17 inches, making it one to consider if you need to carry it regularly or fit multiple safety seats in a row.

While this option doesn't meet every family's needs, given the lower quality and lack of comfort, we believe it is a remarkable option for the price and an excellent choice for anyone with a tight budget who still longs for better crash-test results. It also requires more attention to installation to ensure it is secure, given our experience during testing. For us, it feels right to honor a seat that provides an additional margin of safety suitable for almost any budget.

In our tests, the Britax Boulevard ClickTight ARB earned one of the highest overall results with perfect LATCH and belt installation scores, creating a virtually foolproof convertible car seat anyone can install. As a result of the innovative ClickTight and strap tightening system, this Britax practically installs itself with only a little help from you. We love the non-rethread harness height adjustment with ten levels, seamless soft fabric, a closed outer shell, and three layers of padding for comfort.

This convertible seat is not the best option for families on a tight budget as it is one of the most expensive seats in this lineup. It also isn't your top contender if you want the absolute best crash test results, as its results are average. However, the Boulevard provides impressive performance in most test areas, making it a potential option if your budget allows it. Given that some injuries result from an incorrectly installed car seat, this Britax is a contender for parents concerned with proper installation, thanks to the stupendously easy ClickTight design.

The Clek Foonf is a steel frame convertible car seat that earns top results for LATCH installation and has innovative forward-facing rigid LATCH anchors. The Foonf is relatively easy to install using the vehicle belt, and it offers impressive comfort and quality in its design. This seat has a detachable angle booster, anti-rebound bar, steel frame (similar to your car), and an adjustable headrest, making it a convertible seat parents and babies will love.

The Foonf is a little spendy, so those with a tighter budget must plan or consider a different option. The seat is also a beast, and it's unlikely you'll want to move it often or use it for travel. Despite these minor hiccups, the Foonf offers a lot and includes other safety features. This seat is a unique choice that we believe many families will love. It is the one our founder and Mom-in-Chief, Dr. Juliet Spurrier, uses. Dr. Spurrier's kids love it, and she likes the quality and ease of use.

Read review: Clek Foonf

convertible car seat - best for narrow seat width
The Clek Foonf has the highest weight limit for rear facing installation out of all the car seats we tested. This means baby can stay rear facing up to 40 pounds. Rear facing installation is the safest riding position for baby no matter what their age and it is recommended that baby stay rear facing as long as the seat indicates it is safe to do so.

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. The Nuna offers top performance for comfort and quality and is easy to install, no matter which option you prefer. We like that it is easy to use and the better than average crash test analysis indicates a potential margin of safety over the average option in this review.

Compared to some contenders, the Nuna is relatively expensive, making it a possible no-go for those with a smaller budget. It is also heavy, which means it may not be the right option for traveling or carpooling, as we believe most parents won't want to carry this heavy option for very long. Overall, the Nuna is a quality seat with impressive scores in most metrics, and for families where budget is less of a concern and quality is number one, the Nuna is one for your shortlist of contenders.

Less padding for comfort

The Britax Allegiance is an affordable convertible choice that provides quality for a reasonable price. The Allegiance has the second-highest score for crash test results, with one of the group's best head sensor results. It offers easy LATCH installation, creating a seat with a potential added margin of safety compared to the competition in this review. This seat is also easy to use, so it is an excellent product for a straightforward and safe convertible seat.

With a 7 of 10, the Allegiance is somewhat harder to install using the vehicle belt than some competition. It isn't challenging, but it requires additional attention to detail. It also isn't the most comfortable, with less padding and an unbolstered headrest. In our opinion, despite these concerns, the Allegiance is a seat we believe parents will love for everything it offers and its wallet-friendly price. The Allegiance failed to win an award because of its similarities to the Britax Emblem and the slight price difference. However, we feel it deserves a nod and is a worthwhile option to save you money.

Why You Should Trust Us


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."



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 compliance testing, and we share the detailed crash testing results with you to help you make an informed decision. Then we buy a second unit of each car seat to put through our own rigorous hands-on testing process. The combination of certified crash testing and hands-on testing allows us to evaluate car seat performance from both a safety perspective and a day-to-day use perspective.

Our in-house convertible car seat test protocol development was led by Certified Passenger Safety Technician, Bob Wofford. Bob assesses proper seat installation for the highest level of safety. We also consulted with experts at the National Highway Traffic Safety Administration (NHTSA) 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. Our panel of experts also includes Dr. Juliet Spurrier, a Board-Certified Pediatrician, mother, and founder of BabyGearLab with a background in urgent pediatric care.

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 18 convertible car seats (two of each, actually). Our testing methods include buying two seats, one for crash testing and one for in-house lab testing and real-world use. We conduct a multi-point performance analysis to score and rank crash test results and other functional metrics like the ease of use and installation. We've installed more car seats than anyone on the planet with testing that includes three testers installing in three different vehicles car seats across all categories from convertible and boosters, to infant seats.

The convertible car seats are subjected to more than 39 individual tests to evaluate their performance. The most important rating is the crash test analysis score based on the crash test results from MGA, which corresponds to 35% of the overall score. This metric is influenced by the head and chest sensor data recorded by the crash test dummies in each seat. Our reviews also rely on intense product research and observations from multiple testers to compare each product side-by-side with the competition.

We suggest you keep your baby in their infant car seat until they transition in the 9-12 month age range or as their height starts to push the infant seat's maximum length. You should check weight capacity too, but more often than not, the height limitwill force the switch to a convertible seat.

If you are looking for a convertible car seat, then your baby is at the age range where many parents are also thinking about a baby backpack to make it easier to walk long distances. If you live in a bike-friendly town, then a bike trailer can be a fabulous addition for both you and your baby. Other products that might be relevant for you now or soon include overnight diapers, a portable high chair, and a travel crib.

Analysis and Test Results


We include the details parents require to make an informed decision about which convertible car seat is the best option for their child and budget.

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. A study published in Injury Prevention in 2007 shows that the rear-facing position results in a 5.3 times lower risk of death or serious injury in a car accident compared to the forward-facing position for children age 1-2 years old. The Clek Foonf and the Graco Extend2Fit can remain rear-facing until the passenger weighs 50 lbs. 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.


Value


This group has budget-friendly options with winners and lower-priced seats to meet your needs and safety goals. With several award-winning seats offering reasonable prices and better-than-average crash results, you can find a convertible car seat with a potential additional margin of protection without draining the bank. The Evenflow Tribute LX and the Britax Allegiance earned 8s for crash test results and are among the least expensive in this review. The Graco Extend2Fit also has a reasonable price, the highest crash-test result analysis in the group, and can stay rear-facing longer (a potential safety +). The Britax Emblem is also a good value. While it does cost a little more than those already mentioned, it is still less spendy than the average car seat in our tests and is one of the higher-ranking selections.

Crash Test Performance


BabyGearLab contracts with the same crash test facility that the NHTSA uses to perform our convertible seat crash tests. We purchase two of each seat, and one is sent to MGA, where we pay for crash tests to be completed. MGA test the seats using the same protocol that NHTSA uses based on the FMVSS 213 safety standard.


After receiving the crash test data we commission, we perform a detailed analysis of the sensor data from each car seat's crash dummy to determine how they compare to the competition and the federal standard.

More Money Doesn't Equal Safer
According to our test results, while you might think that a more expensive seat will be safer, this isn't necessarily true. An example of this are the Britax ClickTight seats that provide easy installation features with higher prices but didn't perform as well during repeated crash testing as some of the other contenders. The cheaper Britax Emblem and Britax Allegiance both have better crash test sensor results than the ClickTight car seats proving that price isn't indicative of potential safety. Another example is the Graco Extend2Fit with the best-combined sensor results and a list price significantly lower than the ClickTight options.

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

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

This chart includes the % below the maximum allowed HIC result of each seat we tested in this review. The further below the Federal HIC maximum of 1000 indicates a better result, so a taller bar indicates potentially better protection.


Above, we compare the individual HIC result for each product we tested. This chart helps show the differences between the products and their results. A lower number is better.

The above image is a review of the percentage below the Federal maximum Chest (G) Clip result (60) achieved by the seats we tested in this review. Taller bars indicate better results and a potentially higher margin of protection. Below we compare the chest clip results of each seat, so you can see how your preferred seat compares to the competition. A lower number is preferred.


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 their own tests, and any information they divulge would not allow for a side-by-side comparison of test results. Occasionally, we use test data supplied by NHTSA to supplement our tests. NHTSA also uses the MGA testing facility, and we utilize the same testing process as NHTSA to make an apples-to-apples comparison.

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.

All of the Products We Tested Provide a Basic, Safe Level of Protection
All of the convertible car seats we test 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 a wide margin. These car seats can be considered as providing an additional level of protection based on the data from their crash test sensors.

Additional Safety Features


Some seats have additional features that manufacturers claim will improve the seat's safety; we did not consider these features or claims in our crash test score analysis. 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). Still, we encourage you to proceed with caution when deciding basedsolely 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 in comparison 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.

We rated each seat compared to the competition using a 1-10 scoring system using crash test report analysis. The scoring helps quantify the products that offer an additional margin of protection, in our opinion, over and above the basic level of protection found in all seats.

The Graco Extend2Fit earned our best crash test rating with 9 of 10, thanks to excellent Chest Clip (g) and HIC scores. The Nuna Rava has similar sensor results earning an 8 of 10. While neither have the best score for either sensor, they have the best combined scores for Chest and HIC results. The Britax Allegiance has the best (lowest) HIC result for the group, with a slightly better than average result for the Chest Clip; these results help it earn the group's second-best score with an 8. The Britax Emblem and Evenflo Tribute LX also earned 8s. The Clek Foonf has the best Chest Clip score in the group, but its HIC result is below average, which results in a crash-test score of 7.

Ease of Install Using LATCH


Studies show that more than 7 out of 10 car seats are incorrectly installed, 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.


The Lower Anchors and Tethers for Children (LATCH) installation method should make it easier to correctly install car seats with fewer 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).



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

The LATCH clips on the Boulevard are the simpler version that is somewhat harder to remove than the push button type that mimics a seatbelt.

The Clek Foonf (above left) uses a rigid LATCH connection for forward-facing installation. It is ridiculously easy and requires NO strap tightening. You push the rigid LATCH connectors onto the anchors, and that's it! The Clek Foonf is tied with the Britax Boulevard ClickTight ARB for the highest LATCH installation score as both products do not need manual strap tightening. The Britax Boulevard connectors (above right) are a clip style of LATCH that we feel is more challenging; the clip itself is harder to remove and requires twisting to remove them. The Evenflo Tribute LX has the lowest score in the group for LATCH installation with a 6 of 10.

The LATCH connectors on the Emblem have a one sides tightening strap which in our experience takes more strength to use than some of the unique LATCH straps with center connectors or self-ratcheting features.

Our favorite seat LATCH installation is the Clek because of the forward-facing rigid LATCH installation. The Britax Boulevard ClickTight ARB is also super easy, while the Britax Emblem (above) and Allegiance, and the Chicco NextFit and NextFit Zip are almost as straightforward. The Chicco NextFit has a unique LATCH design with a 2-step strap tightening system that is very easy to tighten, requiring no extreme strength.

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 to use, 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 location? 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 important 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 options that are easier to install using the vehicle belt. Also, you can locate an installation professional for assistance using the vehicle belt if you feel unsure.

LATCH Straps


The LATCH connectors and anchors are only part of the LATCH equation. Whether the straps are easy to tighten and loosen is also something to consider. As previously noted, the Clek Foonf doesn't have straps for forward-facing installation, and the Chicco NextFitand Chicco NextFit Zip have the "SuperCinch" method with a 2-step tightening system engineered to do the hard work for you.



The LATCH straps on the Evenflo Tribute LX are relatively easy to tighten, but we had some difficulty loosening the LATCH strap when trying to uninstall the seat. We preferred options that didn't require extreme strength or bodyweight to tighten the strap or struggle for a secure attachment.

Ease of Install — Vehicle Belt


No matter how or where you hope to install your new car seat, at some point, you must install it using the vehicle belt as LATCH connectors have weight restrictions that most children will outgrow. Also, many center seats don't have LATCH anchors, even though it is the safest location for seat installation. Most LATCH use weight limits are 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 correct installation or where to get help if you are unsure 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, all with forward and rear-facing lock-offs. Interestingly enough, all of these seats ranked near the top and have the highest installation scores using a vehicle belt. Only the Peg Perego Primo Viaggio Convertible scored as well without the help of an onboard lock-off. The Britax ClickTight car seats don't have traditional lock-offs, but the pressure of the seat bottom closure acts as a lock-off and prevents the car seat from sliding back and forth on the vehicle belt, something we often see in lock-off free seats.

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 every bit as secure feeling when installed with a belt as they were 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.

We believe lock-offs can help a seat feel more secure, but some lock-offs are more straightforward. The Clek Foonf lock-off (above left) is super easy to use, even though you need to lift the seat bottom to access the rear-facing lock-off. The Chicco NextFit (above right) is also easy with a lock-off conveniently located on the outside of the shell.

Credit: Abriah Wofford

In our tests, the Britax Boulevard ClickTight ARB is the easiest option to install using the belt, thanks to the "ClickTight" installation method. All you need to do is lift the seat bottom, thread the belt across, remove the slack (don't tighten), and close the seat bottom until it clicks. The seat bottom tightens and locks the seat in place for you. The Boulevard earned a 10 of 10 for this installation.

The Clek Foonf is one of the easier seats in our tests to install using the vehicle belt. The lock-off works smoothly, and the belt is easy to thread. It earned a 9, which is better than the LATCH score of most competitors. The Britax Advocate ClickTight ARB is also easy to install using the vehicle belt, earning a 9.

The seats lacking a lock-off did not score as well as those with a lock-off, with the exception of the Peg Perego Primo Viaggio Convertible. The Evenflo Tribute LX earned just 6 (the lowest result), but interestingly is still easier to install with the vehicle belt than using LATCH. The Chicco NextFit and the Peg Perego Primo Viaggio Convertible earned 8s.

Ease of Use


Convertible car seats have similar designs with few apparent differences that are not cosmetic. However, the options do diverge in ease of use, with some being significantly easier to use than other contenders, thanks to extra features or better functionality of features like buckles.


The Ease of Use metric includes the functionality of everyday features, including harness adjustment and chest clips, ease of tightening or loosening the harness, and fabric cover removal for cleaning. If using your chosen option is challenging, you may not use it as the manufacturer advised, or you could become chronically frustrated.

Buckles and Chest Clips


None of the buckle buttons in this lineup are easy to press with a simple thumb push. While buckles like the Evenflo Tribute were straightforward with sides that pop out with a push, others are so challenging you'll need two hands. Other buckles are stiff, but at least they don't require cussing to use.

The Chicco offers a unique chest clip that has two width settings. This feature made the chest clip harder to use, and didn't seem to improve its performance.

The chest clip is where the harness comes together above the buckle, across the chest. The Graco chest clips are the most challenging to operate during testing, with clips that require excessive squeezing of buttons that hurt to operate. None of the seats provide exceptional buckles and chest clips, but the Britax seats are average and easy to use, which is a good combination. Because buckles are more challenging, focusing on buckle use over the chest clips is best.

The Chicco NextFit has a unique chest clip with a two-setting adjustment for a more customizable fitting. While this design is interesting, we think it makes the clip's operation significantly more challenging. The Cybex Sirona M with SensorSafe 2.0 also has a unique chest clip that includes SensorSafe technology that relays various information to a device connected to the car and your smartphone. While also an intriguing device, it emits EMF, and each parent will need to decide if this feature is compelling enough to expose their child to EMF. The Cybex Sirona S has a strange chest clip as well, with a button that requires pressing to clip and unclip.

Harness Tightening and Loosening


Each seat has a harness tightening strap and a harness release button to loosen the straps. Some of these were harder to pull than others, and the buttons also vary in style and ease of use. The Britax Boulevard ClickTight ARB has the highest score for tightening and loosening. The Clek Foonf and Evenflo Tribute are also easy. The Chicco NextFit Zip has one of the shortest tightening straps in the group, and it took more effort to pull than some of the competition. None of the seats in this review have straps or buttons that are impossible to use.

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 (above left). 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 (above right). 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 seat from the car to reach the seat splitter plate. 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. With the rethread style, we worry parents will put off adjusting the harness when it needs it because it requires an empty seat and takes more effort. Given that injuries can occur when a harness is not fitted correctly, we prefer non-rethread assemblies.

Almost half of the car seats in our review have non-rethread harness adjustment methods. The simplest are the Britax Marathon ClickTight, Britax Boulevard ClickTight, Britax Advocate ClickTight, Britax One4Life ClickTight, Nuna Rava, and Cybex Sirona M with SensorSafe 2.0, which all have smooth moving harness assemblies. The Britax Emblem and Britax Allegiance are also straightforward.

LATCH Storage


LATCH storage isn't as crucial for convertible seats as it is for infant carriers, where they can inhibit carrier connection to the base. However, it is helpful if the straps aren't readily accessible to the passenger and can't result in potential injuries floating loose around the car seat. Some options have designated pockets for LATCH clips, while the most common storage method includes attaching the clips to points on the shell or each other.

The Chicco NextFit (above left) has useful pockets to stow LATCH components and the tether. It is one of the few seats we tested that retain the straps and clips. The Peg Perego Primo Viaggio Convertible, Britax Boulevard ClickTight ARB, Britax Advocate ClickTight ARB, and the Clek Foonf also feature clip storage retention that works well. The least helpful storage type is clip attachments on the seatback (above right) that leave straps dangling and accessible to children.

Cover Removal and Cleaning


Kids' car seats undergo a significant amount of 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 covers that are machine washable and 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. The Clek Foonf is the only option in our review that doesn't have a removable cover; it is spot clean only, and while you can purchase a cleaning kit from Clek, you will likely require a steam cleaner for bigger messes. The Evenflo Tribute LX is a top-performer for removing the cover and straightforward, parent-friendly cleaning. This straightforward cover removes quickly, is machine-washable and dryable, and fits back on the shell without a hiccup. This clean-up process is far better than most contenders that often include handwashing and air drying, such as the Britax ClickTight four-part cover. Probably the easiest and most unique cover is on the Chico NextFit Zip, which has a cover that zips off all the way around for easy removal for machine washing.

Comfort/Quality


For comfort and quality, we consider materials and overall construction. We consider 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.


The seats have similarities like a plastic shell, impact foam, comfort padding, and a fabric cover. However, some offer significantly thicker padding, softer or more durable fabric, steel frames, or foam that doesn't off-gas. Because this is somewhat subjective, the seats are compared side-by-side and ranked in relation to the competition.


The Chicco NextFit (above left), Nuna Rava, Britax One4Life ClickTight, Britax Advocate ClickTight ARB, Britax Marathon ClickTight ARB, and the Britax Boulevard ClickTight ARB are top for comfort and quality. They each offer additional padding with well-fitted fabric and considerations for everything. The Chicco fabric is softer, and the seat is sleek without a lot of useless nooks and crannies. Alternatively, the Evenflo Tribute (above right) is basic and functions well despite the lack of additional features and details with a more unfinished look overall. However, it has a machine washable cover and better crash-test analysis than many competitors. The Clek Foonf, Clek Fllo, Britax Emblem, and the Peg Perego Primo Viaggio Convertible also offer impressive features for comfort and quality.

Weight/Size


We measure the weight and width of each car seat we test, including the forward-facing and rear-facing configuration weight and the width at the widest point, as these can vary. While the seat weight is potentially not as critical as an infant seat's carrier weight, it can be important if you regularly travel or use public transportation (like Uber or Lyft). If your car seat remains in your car for the most part, then weight may not be an issue.


The Clek Foonf is the heaviest option in the review, with a rear-facing configuration of over 38 lbs using the anti-rebound bar and angle attachment; the forward-facing version is over 33 lbs. The Cybex Sirona S is also heavy at a flat 30 lbs in either configuration.

However, the Clek Foonf (above left) is one of the narrowest options at only 17 inches, which means you might be able to use three safety seats across your back seat or two and an adult. The Evenflo Tribute is also only 17 inches wide, but it is the lightest seat in the review at just over 9 lbs. The Evenflo, Clek fllo, and the Clek Foonf are the narrowest options in our tests. Unfortunately, the Evenflo required a towel in our rear-facing tests in at least one of our test vehicles, so you'll need to bring something to use as a bolster depending on the car when traveling (see the user manual). Most of the top seats are more substantial, likely related to the increased padding and steel (or alloy) frames. Many of the top-scoring seats weigh over 20 lbs, which is hefty when you think about carrying them for long distances. The widest option in the group is the Britax Advocate ClickTight ARB at 20 inches, and we think it will be extremely challenging to use it with more than two car seats in a row in most vehicles.
