We purchased and tested 15 highly regarded and popular convertible car seats and discovered that while many products look similar, and can pass the Federal crash test requirements, they are not equal, and all offer a very different user experience. This buying guide is designed to help parents assess and filter the variety of convertible car seats on the market by providing guidance on what you should look for in a car seat and why.
We also suggest parents read our review of convertible car seats to learn which models impressed us during testing and why. If you are having trouble understanding car seat installation, or want to make sure you aren't making any common installation mistakes, you should also read How to Avoid Infant Car Seat Installation Mistakes.
Why Buy a Convertible Car Seat?
While we feel it is the best for parents to purchase and use an infant car seat while your baby is small, you will need to acquire a convertible option after baby outgrows their infant style seat. This change happens when the baby reaches somewhere between 9-12 months of age depending on your particular car seat and how fast your baby grows. We suggest you keep your baby in their infant seat until they transition in the 9-12 months 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, it is the height limit that will force the switch to a convertible seat.
Height and Weight Limits
Most of the seats in this review claim to be suitable for children from 5 lbs up to 40-80 lbs and height of 40-57 inches tall depending on the seat. However, we think the design and features of an infant style seat are far better suited for younger babies, and we think parents should avoid convertible car seats until their baby reaches at least 9 months of age or has exceeded the maximum height or weight limit for their infant seat (height being the more probable limit to reach).
Choose a Seat that Lets Your Baby Stay Rear-facing Longer
Studies have shown that keeping children rear-facing longer is much safer than switching them to forward-facing. The longer a seat can sit rear facing, the better. All of the options in this review can remain rear facing until the baby is at least 40 lbs, with two seats offering a 45-pound limit. The Clek Foonf and Graco Extedn2Fit both work rear facing up to 50 lbs (a big selling point for these products).
A study of 15 years of traffic injury data published in 2007 about Injury Prevention concluded that placing children age 1-2 years of age in the rear-facing position resulted in 5.3 times lower risk of death or serious injury compared to a forward facing position. Please keep your baby rear-facing as long as possible.
So, are the specifications for the car seat's rear-facing capacity a concern? Or, are the front-facing limits more critical? Well, both are important, but if we had to pick one, we'd choose the rear-facing limit given the significant increase in potential safety of children sitting rear facing. The longer a child can sit rear-facing, the better. Even if your child needs to scrunch their knees and have less leg room, it is still safest to be rear facing as long as they are within the height and weight requirements of the seat.
Height Limits Typically Matter Most
A general rule of thumb for these seats is that many children might reach the height limit before the weight restriction. However, this is not a hard and fast rule, so parents should keep in mind the limits on their seat concerning the growth of their child as both are equally important in keeping children safe while riding in a vehicle.
Types of Car Seats
There are primarily two types of car seats, the infant car seat, and the convertible car seat. Both options work with infants, and they have similar features and functionality, but they are not the same. There are pros and cons to type, and we explore that in more detail in our infant car seat review (especially why we feel convertible seats are not appropriate for infants). However, all parents will need to use a convertible seat at some point.
Despite the manufacturer marketing that allows for the use of convertible seats for infants as small as 5 lbs, we think you should wait to use them until after your baby has outgrown their infant style seat. While parents might want to cut corners and save money by limiting the amount of baby gear they purchase, we do not think your child's safety seat is a good place to cut corners. We strongly recommend the purchase of an infant and a convertible seat.
Infant Car Seats
- Separate Bases/Detachable Seats — An infant seat has a carrier portion that can detach from the base that remains in the car. The carrier can be used to carry baby from one place to another and clicks onto the base for vehicle travel. Being able to transport baby from place to place while leaving the base installed, gives parents increased freedom and allows baby to remain sleeping while parents run errands. These carriers can also be attached to a compatible stroller for more convenience on the go. Many modern strollers offer car seat adapters, or you could try a car seat frame stroller. We find being able to click the carrier into a stroller the easiest choice.
- Canopy —
- Lower Weight and Height Restrictions — Even though some of the infant seats will work up to 40 lbs, their range is still smaller than the convertible car seat that often works from 5-65+ lbs depending on the product. This limited weight range is a result of the carrier being specifically for little bodies, as opposed to a design that tries to fit many sizes without fitting any of them well. It is this factor that makes an infant seat perfect for newborns and younger babies, and the type of car seat we recommend for infants.
Convertible Car Seats
We recommend that babies transition from an infant car seat to a convertible seat at about 9 to 12 months old or when they reach the height or weight limitations of their infant seat. The term "convertible" derives from the seat's ability to be used in a rear-facing position and then "convert" to a forward-facing seat for older/larger children. Being able to use a convertible seat with an infant may tempt you into considering a convertible option as your only car seat, but we urge you not to take a "one and done" approach to car seats.
We believe that infant car seats are the best choice for newborns because they are more convenient provide a design specifically with smaller bodies in mind. This type of seat fits infants better, including positioning them better for breathing and sleeping safely. We recommend switching to a convertible seat at 9-12 months age or when baby outgrows their infant seat, as identified in the owner's manual.
Know the Basics
While all the seats available for purchase in the US meet or exceed Federal safety requirements, they are not equal in their crash test results, design, ease of use, or functionality. We will cover the features and performance metrics commonly considered when looking at different seats.
As you might expect, crash tests results are a key metric in the performance of car seats, and thus help differentiate between products. Every car seat must be able to pass a Federal crash test safety standard, with random products chosen by the National Highway Transportation Safety Administration (NHTSA) for testing each year. Each selected seat goes through crash testing in a facility that is designed to simulate actual head-on collisions using a crash sled seat and crash test baby/toddler dummies. These tests collect data generated by G-force sensors located in the test dummies that measure and record the amount of force exerted on the dummy baby's head and chest. This test is a 30 mile an hour crash simulation.
The good news is the Federal requirements ensure that all the seats sold in the US provide at least a minimum level of protection. Therefore, all the products available for purchase can be considered safe.
While each seat meets the minimum Federal safety requirements, some have managed to pass the tests with better results than the others. In our review of convertible seats, you will see that we have combined crash test data we commissioned with similar data obtained from crash tests commissioned by NHTSA. The tests run in the same manner, at the same facility, so we can analyze them side-by-side to demonstrate how each seat compares to the others and the Federal Maximum for allowable G-forces.
Some seats performed better in crash tests, so we gave higher scores to those seats with the assumption that they offer an extra margin of protection based on crash test results. We believe this matters and deserves to be a factor parents consider when deciding which seat to purchase.
It is not enough for you to purchase and use a car seat. You must install and use the seat properly and consistently to help ensure safety. Injury or death can potentially occur in an auto accident if a car seat installation or the child restraints are not correct.
Side Impact Protection (SIP) Claims: Buyer Beware
The photos above show a few of the side impact features marketed by the manufacturers of some of the seats we reviewed. In order from left to right, they are the Clek Foonf with a steel frame for additional SIP, and the Peg Perego Primo Viaggio Convertible that claims "adjustable" SIP.
Because there is no agreed-upon definition of SIP we aren't sure exactly what all of the claims of SIP mean, and little information is provided to support or explain each manufacturer's claims. Clek Foonf does offer more information and transparency on their website than any other we were able to find, including video and results of their side impact crash tests, but overall, transparency is surprisingly lacking across brands.
Currently, there is only a suggested plan for a potentially regulated side impact protection (SIP) testing. However, at this time there is no regulation testing or common language agreement that determines what to test, how to test it, how to interpret results or how companies should define the terms, or what kind of claims they can make. All of the seats in this review claim SIP in the design of their seat or testing process, but the term itself is somewhat ambiguous, as it means something different depending on which manufacturer is making a claim. For example Maxi-Cosi cites independent tests they paid for to determine the efficacy of their design in the case of a side collision. While Graco also claims independent testing for SIP, but their definition and test results only apply to keeping your child contained in the harness in the event of a side collision. We think most parents would assume that keeping a child retained in the seat by the harness is a basic function of a car seat as opposed to a unique SIP feature. Therefore, we suggest that consumers remain skeptical about any SIP claims given that there is no set standard on what it means or how one claim compares to another.
Extra safety features are always a bonus, and we welcome useful and tested safety additions that improve products, but we think parents should be aware of what appears to be some "Safety Washing" happening in the industry concerning the marketing of side impact protection and other features that claim additional protection. Given that there is no industry standard for SIP and other features, and all the manufacturers seem to mean something different, it results in words that have no meaning in and of themselves. This issue requires that parents do further research to determine what manufacturers mean when they claim side impact protection, whether their design or special feature has undergone testing, and what the tests include. That is a big responsibility to dump on parents, and often the information is not available or accessible (trust us, we looked).
We feel manufacturers use SIP and other safety features as a marketing tool to increase product interest. We'd like to see an agreed upon standard for these claims that force manufacturers to focus on engineering designs that provide value and that parents can easily compare. In our effort to determine what manufacturer's means by SIP and other features for additional safety, and their testing process (if any), we had trouble finding compelling information or evidence to support most of their claims which results in an inability to compare the features or even discuss them with clarity.
For the time being, we came up short in our efforts to find credible information or evidence to support the claims.
Forward Facing Crumple Zone
The Clek Foonf claims to have a forward-facing crumple zone designed to help absorb the impact of a collision to help protect the child in the seat. It is the only product in the review that has this kind of design or makes this sort of claim; they are also one of the few to post their testing results online for transparency. The Britax seats all claim an "energy absorbing base," with something they call "safe cell." This feature may be similar to the Clek claim, but once again, without an agreed-upon definition of industry terminology, it is hard to say what one means or if and how testing was done to support the claim. We have no way of knowing how well these features work, or if they work predictably in an actual crash scenario as opposed to a simulated crash test.
Every seat consists of similar kinds of materials and basic design with a few standouts and variations. The majority of the seats have a hard plastic outer shell with a dense foam padding as the second layer. A few of the seats also have metal frame components or features that offer increased shell stability that potentially improve seat performance in the event of a crash (though this is difficult to prove in standard tests). The final component is primarily for comfort and includes a layer of padding and fabric that give the seat its overall look and helps position baby properly in the seat. Many seats also offer an infant insert pillow. This insert is a positioner that helps smaller bodies fit properly in the seat and within the harness. The insert fits above the fabric cover and is removable when your baby grows bigger, or it is no longer needed. Some of the seats also offer padding or "head wings" around the head area. Presumably, this is for impact protection and possibly comfort; some manufacturers explicitly state this is the purpose of the wings, while others refrain from saying anything outright. The lack of manufacturer clarification makes it difficult for us to tell if the feature is intended to truly improve safety, or give the illusion of improving safety.
We believe that the differences in seat construction that really matter are those that reflect in crash test performance, as well as those that impact baby's overall comfort.
The external hard shell is the first line of defense in an accident, as it provides structural support and contains the energy absorbing hard foam molded to the inside. The construction and design work similarly to a bike helmet, by using an exterior hard plastic shell combined with a layer of energy absorbing hard foam placed between the shell and your head.
There are two basic kinds of foam in a typical convertible seat.
- Hard Foam — In our review, every one of the convertible seats has foam as their primary energy absorbing material which helps keep your baby safe in a crash. This foam is either made of Expanded Polystyrene (EPS) (above left) or Expanded Polypropylene (EPP) (above right). EPS is the more common type and is somewhat of the industry standard and found in the majority of seats we tested. Alternatively, the Britax seats use EPP foam. We like the EPP better and feel it has a slight edge over EPS because it is somewhat forgiving when bent or pressed on, where EPS will break or deform, and it doesn't off-gas like EPS, which we prefer. The EPS foam, comparable to the foam found in most bike helmets, is common for impact protection applications. The greater difference between seats is how much foam they have and where it is inside the shell of the seat. A few seats have foam inside the entire shell, while others had more foam in the torso and head region with little to no foam in the bottom of the seat.
- Soft Foam — We tested some seats that provided a softer foam around the head portion of the seat. A good example of this is the Chicco NextFit or the Peg Perego Primo Viaggio Convertible, which both offer a significant amount of additional soft foam around the head area. Soft foam doesn't offer much regarding impact protection in a crash, but it does offer extra comfort in everyday use. Alternatively, the Maxi-Cosi Pria 70 has a soft foam head pad surrounded by a plastic bag they call "Air Side Impact Protection." The manufacturer claims this feature tested has been tested by an independent lab to determine its ability to decrease injuries related to side impact crashes. However, this type of functionality is not the norm, and most of the soft foam on seats are either for comfort or to mimic the look of impact resistance.
Anchoring the Car Seat
There are two different methods used to secure a car seat in a vehicle. We will provide you an overview of each, including the most common reasons to use one over the other, or when you might need to use one over the other based on manufacturer guidelines. You can find more information about installation in our article, How to Avoid Infant Car Seat Installation Mistakes.
To properly install your car seat you need to read not only the car seat user's manual but your vehicle user's manual as well. Why? The vehicle manual is the overriding authority on how to install the car seat and supersedes the car seat manual if the two directives conflict. The vehicle manual is especially important when determining how to install a car seat based on your child's weight. Some car seats require a change from LATCH anchors to seatbelt installation when your child reaches a certain weight. However, your vehicle manual will also have limitations on how much weight can be attached to the LATCH anchors. So if your car seat manual says the seat can be installed using LATCH up to 60 lbs of child weight, but your vehicle manual shows a limit of 50lbs, then you must switch to the seatbelt installation at 50 lbs, not 60.
- Installation using LATCH connectors — Beginning in 2002, the majority of cars in the United States have the mandatory LATCH (Lower Anchors and Tethers for CHildren) on the left and right rear seat positions (not the center seat). This type of connection was created to provide a simpler method of attaching car seats to vehicles. We recommend using LATCH when it is available since it is usually the best and easiest way to ensure a tight, secure connection.
- Installing with a Seat Belt — You can install all the seats using the vehicle seat belt through the designated pathways provided on the seat. Some products have a built-in lock-offs while others do not. We found the lock-off usually makes this process easier. Only a minority of vehicles offer LATCH connectors for the vehicle center seat, so a seat belt might be your only option if you want to use the center seat. Also, once your child reaches a certain weight, the seat belt installation often becomes your only install option, as the LATCH system will become unsafe due to the combined weight of baby and car seat (see tip above).
Placing the car seat in the center position can reduce injury by more than 40% compared to installing the seat in a side location.
During our installation testing, we found significant differences between car seats regarding ease of installation with a seat belt depending on the vehicle we were using. Parents who plan to use this location exclusively may want to install their seat of choice in this position to ensure that a good fit is possible before choosing to keep it (Amazon has a great and easy return policy).
Both methods of installation are possible whether the seat configuration is rear-facing or front-facing. Depending on the laws in your area, children need to be restrained rear-facing up to a certain age or weight range. We recommend you keep children rear facing as long as possible (within the guidelines of the seat) because it is safer for children in the event of an accident. The choice of how to install is somewhat up to you and what works best for your car, but all seats will eventually need seat belt installation because the LATCH method has weight restrictions.
Each seat we tested has a level indicator to help parents confirm when its installation angle is correct. While they don't all look or function the same, they all provide similar information and guidance.
Some of the level indicators are lines on the seat that are either molded into the plastic or imprinted on a sticker on the side of the shell. The level line should be parallel to the ground after installation and is best to observe by standing back from the vehicle. Some indicators look more like a traditional level you'd find in construction with liquid and a bubble, or a small ball that rolls inside a plastic casing that indicates the seat is installed at the correct angle range when it falls within a pre-marked area in its path. It is important that parents use the level as instructed in the user guide with their seat.
Shoulder Height Adjustment
Adjusting the shoulder height of the harness on a car seat may not sound like a big deal until you have to do it. Being able to alter the harness quickly and easily means your child will be using a correct fitting harness at all times. Avoiding changing the harness height because it is convoluted or difficult to operate, could lead to improper restraining in the seat. Not using the harness or seat correctly could lead to injury or possible death in the event of a crash, so this is an important feature to consider on any seat.
Rethreading harness straps to adjust shoulder height is the most difficult method of adjustment in the seats we reviewed. Rethreading requires that you remove the harness straps from a connector on the back of the seat, and unthread the straps from their current slots through the back of the seats to move them to higher slots. The process itself isn't that difficult, even though it is convoluted. However, you usually don't notice you need to adjust the straps until your baby is in the seat. This process means you will need to remove your baby from the seat and possibly the seat from the car to adjust. Then you will need to reinstall the seat before you place your baby inside and get on your way. We worry that some parents will procrastinate making adjustments for this reason. This hassle could lead to a cycle of forgetting to do it time and time again leaving your child driving around in a poorly fitting harness. Do NOT do this!!
The easiest to change, and thus our favorite seats, are those whose height can move without the need for rethreading. This design means no splitter plate, no moving the harness straps from one slot to another, no removing baby from the seat. This kind of adjustment can happen on the fly as soon as you notice the harness needs changing. It is a quick and relatively painless process that requires either pushing a button, pulling a tab or moving levers in and then pulling the headrest/shoulder portion of the seat up to the required height. The Peg Perego Primo Viaggio Convertible, Britax Boulevard ClickTight ARB, Britax Advocate ClickTight ARB and Britax Marathon ClickTight ARB, Essentials by Britax Emblem, and the Essentials by Britax Allegiance all have non-rethread harness systems that are easy to adjust and nicely designed. These were not the only options with this feature in the group, but they are the ones we liked the best.
Harness Tightening and Release
Once the shoulder straps are adjusted, and your child is in the seat and buckled in, the entire harness tightens by pulling on the strap that trails from the foot of the seat. This process should be easy, and in theory, it is, but not all tightening straps are as easy as others.
Most of the harnesses we tested loosen by pressing a button near the foot of seat, while others worked by lifting a small lever in the same location. The button or lever should be somewhat stiff to operate to prevent little hands from pressing the button. However, they shouldn't be so difficult to use that an adult can't do it with one finger. Some seats have buttons that are visible on top of the seat fabric, while others have the adjustment hidden under padding and fabric to help little ones avoid temptation (out of sight, out of mind). The Britax Boulevard ClickTight ARB, Britax Marathon ClickTight ARB and the Britax Advocate ClickTight ARB have an indicator click sound that tells you when the harness is tight enough, though we still recommend parents use their best judgment and check the harness before believing an external system.
The buckles on the majority of the seats we tested are so remarkably similar we can't help but wonder if some of them come from the same assembly line. Many were easy enough to use, and while there is a pressure metric they need to meet, some were too stiff and hard to operate. If you have any thumb strength or structural hand issues, this might be more important to you than it is for others. The Maxi–Cosi Pria 70 earned the highest score for buckle ease of use, while the Diono Radian RXT is the most difficult.
While the weight of the carrier in our review of infant seats was important because you need to transport the carriers from place to place, the weight of the convertible seats is less important in our minds because you won't be carrying them around that often. The Clek Foonf is a very heavy seat at 38 lbs and 6 ounces; it is cumbersome to carry and more than a handful. However, given that you will rarely be moving it or transporting it, we don't feel this is a deal breaker or high on the consideration list for most parents. The Britax Boulevard ClickTight ARB and Britax Advocate ClickTight ARB came in with the second and third heaviest weights for the group. Alternatively, if you will be moving your seat or using it for travel, you might be interested in the lighter weight seats like the Evenflo Tribute LX that is only 9 lbs 4 ounces.
Sometimes the biggest differences between seats are smaller details. In a product genre where so many of the seats are similar in structure and function, the details are the only thing that helps differentiate them from each other. With gear that is so heavily regulated, it could be difficult to tell one product from another, or for parents to decide why one is better than another without considering the features that make them stand out.
While the jury is out on the efficacy of the anti-rebound bar offering additional protection, general physics seems to support the claim that it does. This bar works on the rear-facing seat and prevents the seat from dramatic flipping back against the vehicle seat back in the event of a crash. It is the back and forth motion that causes head and neck trauma in a collision, so less movement theoretically means fewer injuries. Even though we like the idea of the bar, we think that currently there is not enough information available for caregivers to believe that the absence of this should be a deal breaker. For the time being, we think it is a nice addition to an otherwise high-scoring seat, like the bars found on the Clek Foonf, Britax Boulevard ClickTight ARB, Britax Marathon ClickTight ARB, and the Britax Advocate ClickTight ARB. However, we wouldn't overlook a high scoring product without a bar in favor of a lower scoring option that has one. Luckily, these seats earned higher scores in our review, so you can purchase a high scoring product that also has a rebound bar.
If you use the seat belt to anchor your seat to the vehicle instead of the LATCH connectors, it is important to have a spot to store the unused anchors. Unlike infant seats, where the anchors could get in the way of proper attachment of the carrier to the base, the anchors on the convertible seats are more of a nuisance than a potential hazard. Not all of the storage options are great, and we prefer the options that keep the anchors attached to the shell body, so they don't come loose. Chicco NextFit has interesting plastic side pockets, which are sort of hard to use but keep them out of sight. It probably isn't necessary though, and any seat that keeps them connected to the shell seems to work fine. Clek Foonf has rigid LATCH anchors that pull back under the seat and rear facing anchors that tuck under the seat bottom.
On each seat, there should be a spot to store the user's manual. You should have easy access to it in case you need it, but it shouldn't be where little ones can find it or where spilled items and vomit can reach it. Onboard storage helps keep answers at your fingertips to improve overall use and safety. It is important to use the storage space as intended, so you aren't caught without the manual when you need it. Some of the seats store the manual under the padding where the child would sit, which seems like a bad spot and one where it could easily get damaged, though this is better than locations where children can find the manual and destroy it before you notice. If you lose the manual or it does get damaged, most are available online or you can order a new one from the company. It is far better to do the extra work to get a manual than it is to guess on specific installation or design information about your seat.
How do I decide which convertible car seat is best for my child?
With so many options and features to choose from, the decision on which car seat to buy can feel daunting. We've broken the process down into steps that help you determine what to consider when deciding which option is best for you and your child. While there are several excellent high-scoring products in this review, your particular needs or limitations might find you choosing a different model that works best for you even if it didn't win an award in our tests.
Step 1: Consider Where the Seat Will Go --Installation
As previously discussed, where you plan to install the car seat may impact which seat you choose to purchase. Where and how you plan to use the seat might also influence you. Your usage pattern can make the difference between which option best meets your needs and which will be frustrating to use. Given that more than 80% of car seats have been shown to have at least one serious problem with installation, choosing a seat that is easy to install in the location or locations you choose will help keep baby safer.
If you reside in a major city and will need to transport your little one in a cab or Uber, you may want to look at some of the lighter weight seats. This would also be true if you travel frequently and plan to lug a seat through the airport or on a train. Some of these seats are heavy, and this should be a factor for parents who won't be installing the seat in their car and forgetting about it. The Evenflo Tribute earns high marks in crash testing, and at just over 9 lbs you will probably have an easier time carrying it than you would the Clek Foonf at over 38 lbs in its rear-facing configuration, or the Britax Boulevard ClickTight ARB at over 28 lbs.
Center or Side?
Will your seat be installed in the center seat or on the side? Some vehicles do not offer LATCH connection points for the center seat, so you will want to check your vehicle for anchor points. Alternatively, you can install the seat using the belt only, and we found during testing that many of the seats feel very secure installed using a lap-only belt, and some were even easier to install with the vehicle belt than with LATCH.
Research shows a 43% lower risk of injury for car seats secured in the center, but the center location is only safe if you properly anchor the seat. The research also shows that more than 80% of car seats have a minimum of one serious problem with installation. Therefore, we suggest parents take ease of installation as seriously as we do.
We think it is worth noting that 61% of us parents, place car seats on one of the side seats. The side seat is more convenient for getting the child in and out of the vehicle, and it is the only option for families with multiple children or those with vehicles built before 2002.
Making mistakes when installing a seat or securing the baby in the seat is common. Because of this, we have dedicated a separate article to this topic. It is crucial that car seats be correctly used for them to work properly. For this reason, we advocate parents consider ease of installation and ease of use as critical factors in their buying decision.
Step 2: Ease of Use
Because installing your seat is likely to be only an occasional process for most parents, it is the daily ease of use that will impact your experience and overall safety of the car seat. Getting your child into and out of the seat, as well as strapping them into the harness are activities you will need to perform on a daily basis. How difficult these activities are will quickly become more important to you than how difficult it is to get the seat anchored into the vehicle.
Ease of use varies from seat to seat with scores between 4 and 8 in our testing. Chances are you have a few seats on your list after considering installation locations and how easy it is to install. Finding the seat or seats in this list that also offers nice ease of use score should help narrow the options further. All of the Britax options, including the Essentials by Britax, earned a high score of 8 for ease of use. Check our ease of use ratings to narrow your list down. The Evenflo Tribute LX and Peg Perego Primo Viaggio Convertible scored 7s in this metric making them each a second place for ease of use.
Step 3: Crash Test Performance
All the seats in this review have passed the minimum requirements for crash tests as outlined by Federal guidelines. Therefore, all offer a basic level of protection, but some seats perform significantly better than others and can be considered as offering an extra margin of protection compared to other seats.
Many parents might consider crash test performance to be the most important factor in choosing a seat. However, we feel that because installation and ease of use impact a parent's ability to use the seat correctly (and therefore safely), and it also influences the overall crash safety of any seat, that you should consider it before the actual crash data comes into play. Given that over 80% of parents install or use their seat incorrectly, it matters little how safe a product is if you don't use it correctly. After finding a seat that is easy to install and use, then it is important to find one that will function well in the event of a crash after you install it correctly and strap baby in according to the instructions.
To evaluate the crash test data of each seat we reviewed, we analyzed their crash test results to compare how each seat performed in comparison to the federally required minimum score. Also, we assessed how well each seat performs compared to the other products in the review. Now that you have narrowed down your list to a few finalists, you can use our crash test analysis to choose the seat that offers an extra margin of protection for your final selection.
The foam used to construct car seats has an actual shelf life, so after a certain period, you should no longer use the seat, and it should be destroyed. If you choose to use a hand me down car seat, you need to ensure it has not already expired and that it won't expire in the 9 to 12 months that you will need it. Also, it is important to retire any car seat involved in an accident. Even if the seat appears to be uncompromised, you should still discard it.
Purchasing a convertible seat does not need to be a daunting experience despite the plethora of options on the market. With a few key considerations and a review of the details on how each seat compared to the rest, you have all the information you need to determine which seat will work best for your family. We believe the award winners can fill the niche for just about any need and budget, but if you find another seat in the group that looks more worthy for you, compare it to the top scoring or award-winning products in this review. The variety of options might seem overwhelming, but we have your back with information and a detailed analysis of many of the viable candidates so your decision can be as easy as 1,2,3.
Optional Reading: Car Seat Lingo
To help you understand all things car seat, we have provided a little terminology insight that you might come in contact with when reviewing car seat information. Knowing the lingo can help you stay the course and ensure that you understand the details of what you are reading. This knowledge is important for interpreting information easily.
The terms and definitions are from the National Child Passenger Safety (CPS) Certification Training Program manual, and while some definitions have been slightly changed to increase readability, the intent/meaning is the same. You can read these definitions here.
