Robert. Well, I'd say foam! Naturally the lighter the less support, so you may want to build up a few (3) layers of stuff just like the upholstery people do. Start off with a more dense which will be heavier and then to a medium and then to a light. That way you'll have the support on bottom and the top will be softer and more comfortable. If weight were not a consideration, and it always is, I'd say put a 1" piece of NASA foam on top. So comfortable you'll fall asleep at the wheel! But, alas, the stuff is heavy!!!
Good project to take some pics and write an article for your favorite magazine or Hartmut's web page.

Checking further, I lifted out the seat cushions, opened up the upolstery and found them stuffed with some really heavy terry cloth type material. We were guessing that the 2 seats felt like they weigh about 40 pounds together so they probably really weigh abot 20-25. What is a good, firm material that can be used in the seat cushions that doesn't deform a whole lot and is fairly light?
