Ball Chairs

Ball chairs can help pelvic anteversion and therefore stacksitting, and therefore be helpful. I'm not crazy about the notion of sitting on a moving ball, because I think sitting should be relaxing. A stable ball like this takes care of the rolling  around problem (that others seem to seek out!) No matter what the chair, there really isn't a substitute for knowing what to do with your body in the chair. People can sit poorly (swaying or even tucking) on any chair including a ball chair.

I just realized I answered this question here as well: http://gokhalewellness.com/forumtml
