Title: Not as great as I expected
Review: I have hip and knee problems and was experiencing some discomfort in my regular office chair so I decided to give the balance ball chair a try. Personally, it caused an increase in my pain specifically in my hips and lower back. I think the problem may be the back support bar, which as another reviewer mentioned, is removable. I have been using just a plain large balance ball as my chair the past few weeks and like it much better, so you might want to give that a try before you purchase the whole chair get-up.
