Fleece is fine but as you say, its also very hot to sit on all day. Try one of those hemmoroid donuts made of plastic. They are a bit bouncy so the recipients bottom barely touch trhe seat and plenty of air gets through. They take the strain off the spine as well. Oh oh, he'll need a lapghan to keep his legs warm in the cooler weather as well. Perfect size for wheelchairs. Hummm, I better get cracking!
