I was thinking about hot wire cutting some foam padding that would be bonded and sculpting to the seat. Then a leather / plastic coating.

Due to a workshop move, I no longer have room to store to the steel seats I fabricated. I need to get rid of them by next Saturday at the very latest from Plymouth Devon, or I will have no choice other than to put them in the the ever increasing scrap pile. I would rather they went to a good home if they can be of any use to someone and can continue this part of my project.
