I use a Bungee Chair, similar to: http://www.containerstore.com/shop/desks/deskChairs?productId=10022641 I had purchased a nice office chair from COSTCO previously, and as much as I love COSTCO, I absolutely hated the chair. I think it single handedly led to some RSI and constant headaches. After some research, picked up one of these and I'll probably never use another type of office chair.
