We have a van (2001 dodge grand caravan) with built in fold down car seats. We've never used them, but I like knowing that they are an option for "back up" for situations like, being able to drive a friend's kids at a moment's notice without worrying about having a car seat available for them. But one thing I'm wondering about is, the back of them is just hard plastic. It looks terribly uncomfortable and I sure as heck wouldn't want to sit there. But there's some velcro pieces there that make it look like there's possibly supposed to be some sort of padding that attaches, but it vanished some time over the years (we just bought this van a couple months ago) Does anyone know if there's supposed to be something that slips in there, and if its possible to get a replacement? I'd almost ask if it would be okay to tuck a blanket in there to soften it up a bit in a pinch but I've seen more than a few threads talking about absolutely nothing goes between the straps and the child!
