: I was in an auto accident over twenty years ago...... The M.D. felt a flat Thermarest type of seat was superior......

Ouch! Hate it when that happens. I surgeon friend mentioned that medical equipment companies sell a bag of liquid foam that you sit on and it gels and solidifies to the contours of your fanny. The surgeon friend gleefully asked the med supplier how much? About $350! Ouch I hate it when that happens. Perhaps there is a cheaper way to get the same result. I guess I will stick to the carving minicell technique for now. Hope you get some useful responses.
