I have done a search on rebuilding car seat foam. I rebuilt my drivers side a few weeks back. It came out okay but not 100%. I had to pack in a lot of foam to get the correct shape and it gets uncomfortable after about 20 miles of driving so I have to try it again.
I see there are a few mentions to using a "steam machine" on the foam to bring it back into shape. Has anyone ever used one and are they a success. I am trying to find one here. What do they look like. Are they like an electric kittle with a nossle on it.
