what about aeron chairs? They "suspend" me in a good position, whereas other chairs cause soreness if I sit for long periods of time.
What I've noticed from years of "sitting jobs", is that you need to keep the hips, lower back firing/moving. Exercise balls helps a lot. I love siting on exercise balls, as they keep the hips, lower back engage. While sitting on my ball and working, I can rotate my hips in any direction, keeping my muscles stretched/firing. Even those "sitting discs" work well: http://www.amazon.com/FitBALL-Seating-Disc-12-Green/dp/B0011...
