Britax Baby Safe car seat cover?

Question

UK moms! I’m not in the UK, but have a friend coming from there later this month. I’m desperately looking for the above car seat cover but the only place I can find it is the Britax Roemer website! Any ideas if any baby stores around London would be able to get it for me pls?

Answer

If it’s from the original manufacturer then it’s fine. What’s not is the aftermarket stuff you find in generic stores that you add. This is a complete replacement

Answer

What country are you in? Did your car seat come from the UK?

Answer

I thought baby seat covers of any kind are unsafe? They affect the car seat's ability to protect your child and hold them securely in place in the event of a crash.
