Same as Constance. I have an extended rear facing axkid one. It's up to 25kg and 125cm so plenty of space to grow. I always thought they'd need something else when their legs gone too long, but honest they are more comfy with their legs up etc.
I’ve got a besafe stretch which is an extended rear facing seat. It goes up to 125cm/36kg, which ever comes first. Would highly recommend x
My daughter has the grace slim fit 3 in 1. I love it!! My son we got a different one but I’m gunna switch him that the frack one. It’s easy to get in and out and it’s comfy and lots of positions
We have a Britax romer safe way m or max way pro. They should last rear facing until 6/7 yrs old. Swedish plus tested and really reasonably priced!
We tried them out in John Lewis first… well worth a visit, no pressure to buy if you need to shop around.
Going for an axkid for extended rear facing!
We’ve got a few different seats across 3 cars, all ERF, but the axkid minikid 3 is my favorite (replaced by the 4 now) there’s an extended rear facing car seat group on Facebook you could join for more info x
Besafe stretch, our son loves it x
Mine are in extended rear facing seats which can last till they are 5+ I’ve got the axkid minikid for my tall 3.5 yr old and he’s got loads of room left to grow ❤️
