Car Seat Compatibility Checker

If you’re shopping for a car seat, safety is everything. The good news is, all car seats sold today are designed to meet UK safety standards, and some models even go above and beyond with added features like side impact protection.
However, just because a car seat is deemed “safe,” that doesn’t necessarily mean it will be safe in every vehicle. If a car seat is installed incorrectly — or if it isn’t compatible with your car — your little one is at greater risk of being injured while the vehicle is moving.
In this guide, you’ll find everything you need to know about popular car seat brands and their fitting lists, so you can find the safest car seat model for your vehicle.
