Britax adventure highback booster

[ram2014]

Hi
I got a britax adventure highback booster today and wondered if someone could help me.
The backrest slides back and forth, if that makes sense. It doesn't lock into place, like it does with my stage 1 seat when in recline mode. So of there was an accident the backrest would move with the child.
I don't know if my description makes sense, but hopefully it does.
Is this meant to happen with a highback booster or is it faulty?
There is no information at all that I can find on the manual about the backrest moving.
Hope someone can help as I am so stressed with these car seats and I don't even own a car!

I think it's normal. I have this car seat and mine's the same. I suppose the purpose of the booster is to raise the child so the car's seatbelt can do its job.

Okay brilliant, thanks.

Yep, I have two of them and both do that. I think it's just to give a good fit and allow for differently-sloping vehicle seats. Or seats like the ones in my Peugeot 5008 that you can recline slightly - if I recline the car's seats the Adventures fit well in their 'reclined' position too. It just helps a bit if we're en-route to an airport or driving to Cornwall and the kids want to sleep.

Normal and I think all boosters do this. Isofix ones possibly don't. The difference is not using their own straps but using the car seat belt. If you do a sudden stop, the child, seatbelt and car seat back will all move forwards, the belt is held in place by the seat guide, so in fact it's probably by design.

Don't worry :) It's a great seat if you don't drive.

We also have a Britax KidFix ISOFIX high backed booster and the back is 'loose' on that too. When you have attached to arms to the ISOFIX brackets in your car you push the bottom part of the booster into the seat until it's close in and has 'locked' but the back still moves slightly and will definitely move forward with the child in the event of a crash. I don't see a problem with that.
