**I gave this 4 stars instead of 2 - while the chair didn't work out well for me, my co-worker really likes it.**
I wish I would have tried this out before purchasing.  It has very little padding on the seat which makes it uncomfortable about 2 hours into my day.  I sit for longer times when concentrating on designs and this chair makes my lower half tired after a short period.  Granted, I probably need to get up and move around the office far more than I do to help circulation.
