Should You Work On A Ball Chair?

Nope:

Although you might expect that sitting on the ball would demand extra exertion to keep you upright and stable, when Dr. Callaghan and his colleagues had healthy young volunteers sit alternately on a ball, an office chair and a backless stool while machines measured muscle activity in their abdomens and lower backs, they found no meaningful differences in the seating options; sitting on a ball did not provide a mini-workout for the midsection.

Ball chairs do not improve posture, either. Research by Dr. Callaghan and others have shown that people generally slump just as much on a ball as in a normal chair and that back pain is not reduced. And, in part because sitting on a ball chair involves more contact area between the seating surface and your backside than a chair does — you sink into the ball somewhat — many new adopters of ball chairs report increased discomfort in their backsides.
