What our testers said

“Britax is a very reliable and well made quality child seat. It is my trusted brand of 30 years of using car seats.” – Childminder

“It’s reassuring to know that it provides a lot of protection and allows the baby to sleep in the car.” – Aunt of 4 month old

What our experts think

The Britax Römer is a wonderfully high-quality car seat, with a sturdy and comfortable design. The 360° turn means that it can grow with your baby, by switching from rear-facing to front-facing. This also makes it easier to get your little one in and out of the car, especially as they get bigger and heavier!

The seat is really comfortable and supportive for your baby, with a good headrest. Our testers found a slight problem with neck dropping, but this can be remedied by ensuring the child is positioned correctly and checking them often. The cover is easy to remove for cleaning and there is an instruction video available to help you.

Overall this is a great car seat, secure for peace of mind, easy to use and clean for convenience. It’s a little chunkier than others, so will suit you best if you plan to keep it in one car and are happy to move your baby to a pushchair when out and about.
