thanks for your reply its rubbing the top of the rear door card, its damaging the leather trim along the top of the door card, where the top of the carseat is rubbing aganist it. i have tried putting a sponge there but it just flattens the sponge in a couple of days then just rubs again. i have tried putting some other things there too but where baby moves it then makes the thing i have placed there move.i think its becasuse the child seat has a large section at the top which supports the babies head, think the seat needs to go and we need to get another smaller one just wanted to see if anyone else has a child seat in the back and which one they would recommmend. thanks for your help emily
