Discover the three best and worst extended rear-facing child car seats with our useful car seat guide – newly updated with the latest crash test results.
The most dangerous car accidents are generally frontal collisions, and they’re also the most common. Rear-facing car seats protect children from the forces of the crash which would otherwise send their delicate bodies, heads and necks forward with great force.
In our unique guide we bring together the test results for the top three, and bottom three, rear-facing car seats. This has now been updated with our latest crash test results.

Car seat reviews
Which? has tested hundreds of rear-facing child car seats over the years, from brands including BeSafe, Britax, Cybex, Joie and Maxi-Cosi, including many of the common Group 0+ infant carrier type car seats, which are suitable for babies.
We’ve found good and bad examples of both, so buying an extended-rear facing car seat doesn’t necessarily guarantee the safest car seat. And you can’t tell just by looking at a car seat how it will perform in a crash.
The table included in our guide makes it quick and easy to compare the three top-scoring extended rear-facing car seats, and check out which three are at the bottom of our table.
How we test car seats
Which? is the only car seat review website that actually tests car seats in two crash simulations: a front crash, equivalent to a head-on collision at around 40mph; and a side-impact crash.
Our tests reveal big differences between child car seats. Some protect babies and children well, but others expose them to the risk of serious injury.
We also check how easy car seats are to install. A car seat can only offer maximum protection when it’s installed correctly. For any that are too complicated, or where there’s a high risk of incorrect installation or misuse, we downgrade the total test score.
