Is there any foam in the rear sear or just springs or what? Mine squeaks alot when someone is in it and I just want to completely redo all of my seats and was sondering if there is more you can do to the rear seat than just covers.

Yes, there is foam and also cotton or polyester batting on top of them. There is also a burlap covering directly over the springs.

That has no bearing on squeaking springs, however.

If you are planning on replacing the covers, that is a good time to check into the springs.

There could either be one broke or the (bw) clips that connect the springs to the frame are loose.

When you get your old seat cover off, strip the rest of the foam, burlap etc. down to the bare frame/springs, and you should be able to find the problem that way. Make sure you keep track of where everything goes back together.

You might be able to reuse the (bw) clips, but if not any upholstery shop carries them and they are not expensive, and you may need to get hogrings as well if they aren't included with your new covers.

Hope this helps.
