Searching for the best convertible car seat with the crash test results is such an uphill task. This is because, although all manufacturers claim that their seats are safe, they do not provide actual crash test results conducted on their car seats.
When it comes to the safety of a car seat, the only requirement by law so far is that the car seat should meet Federal Motor Vehicle Safety Standard (FMVSS) No. 213.
So for this review, we have had to rely on findings of NHTSA (National Highway Traffic Safety Administration) ratings and other credible organizations such as Consumer Reports and Baby Gear Lab who conduct their own independent research. These organizations conduct detailed testing to see how easy it is to use and install the car seat and do crash testing to determine how the car seat will hold up in a frontal and side-impact.
That said, below is our list and reviews of the Best Convertible Car Seats with crash tests.
Reviews of the Best Convertible Car Seats Crash Tests 2021
Britax Emblem is among the best in class when it comes to your child’s safety. It was given outstanding crash test scores by the Baby Gear Lab, even more than Britax high-end models. NHTSA gave it a four-star rating for overall ease of use and for better comfort, this seat has adjustable non-rethread shoulder straps and comfort padding.
This car seat is a valuable investment that your child will use from 5 to 40 pounds in the rear-facing mode and 20 to 65 pounds forward-facing. It’s comfortable with high quality and super soft fabric, generous foam padding, and two recline positions.
In terms of safety features, the car seat is engineered with an impact stabilizing steel frame for superior strength and stability. It is also equipped with two layers of side impact protection and a quick-adjust foam-lined shell for head and neck protection. Plus, an impact-absorbing base that minimizes collision force.
Other great features include 10 headrest positions, a no-rethread harness, lower anchors and built-in lock-off for LATCH and seatbelt installation, and a removable machine washable cover.
Unlike Britax Boulevard ClickTight model that costs almost $150 more, Britax Emblem has a manual LATCH strap and required much more effort to install. The process itself isn’t long or complicated but if you prefer an easy-to-install option with Latch hooks and clips, you can get the ClickTight model with average crash test results, rated lower than Britax Emblem.
We have a full comparison of Britax Emblem and other Britax models such as Marathon, Allegiance, and Boulevard.

What to consider when purchasing Safest Convertible Car Seat crash test ratings
Choosing a convertible seat is an important undertaking, and a lot has to be taken into consideration. Here are some factors to consider:
Safety: Ensure that your car seat meets and exceeds federal safety and crash performance standards. All NHTSA-rated car seats are safe. The convertible car seats listed here have also been tested by credible independent bodies and also have great safety ratings by parents.
Ease of installation: a car seat may have all the best safety systems in place, but if you can’t install it correctly or secure your child properly, it will not provide desired safety for your child. To prevent improper installation, buy a car seat with a fail-safe installation system. Today, most cars are equipped with LATCH (Lower Anchors and Tethers for Children), which makes it a lot easier to install car seats properly.
Ease of use: check features that make it easy to install, adjust to other modes, and get your child in and out. You can gather this info from sites like NHTSA, Consumer Reports, and also by reading reviews of parents who have had experience using the seat.
Car compatibility: car seats will fit differently in different cars. So, measure your backseat dimensions and compare them to the seat dimensions to see if it will fit. This is especially important if you have a small car.
Height and weight limits: Every car seat model has its own limits. The best convertible car seats are those that allow extended rear-facing weight range. The APP recommends the past 2 years; up to 4 years is even better.
Longevity: Convertible cars are designed to last for years. The best ones expire after 10 years, but some also go for only 7 or 8 years. The rule is never to use a car seat after the expiration date, even if it seems in perfect condition. So, check how long you have before the seat expires.
Lifestyle: most people buy a convertible seat to keep in their car seat, but if you are a frequent traveler, the seat’s dimensions and weight will be an important factor for you.
