[_paralyzed_]

The insurane has a lot to do with the price, so does the liability. Cushioning for the chair is a whole other ball of worms, it's better to have a flat base in standardized sizes to accept available cushions. Standards are in two inch increments, for example, I am in an 18x20 cushion, a very common size is the 16x16. My cushion cost $500. It has a gel lining and foam and a neoprene cover. It could definitely be made cheaper, but let's get the chair first!
