I know there was a discussion on seats somewhere, but couldn’t find it.
We spent last couple days replacing the foam in our seats. I picked up some 5″ very dense foam from a local upholstery shop (the owner recomended this). I was concerned about the thickness but this guy knew his stuff. WOW what a difference, hopefully the end of ‘TBS’ (tired butt syndrome). We did a test drive before we torn the seats all apart, and after an hour drive no pain. Tomorrows another test a longer drive.
The hardest part was removing the carpet glue from the vinyl on the bottom, not sure what CMC used, but it was stuck and nothing really disolved it. Once all cleaned up it went easy. Foam cuts real easy with a electric carving knife, in case anyone needs that hint. Cut the foam, insert it into the seat cover, lay the plywood base on the foam and staple it all back together, oh you may need something heavy to press down on the plywood to depress the foam a bit to get the vinyl to stretch. About a hundred pound wife works pretty good. She actually stood on it and I stapled. Good balance is a plus too.
