There must be a lot of uncomfortable people sitting at their desks right now, because we're noticing a trend moving away from conventional seating and into some rather odd-looking designs that are endorsed by members of the medical community. In fact, this BalanceBall chair is remarkably similar to Doctor Riter's ErgoChair we pointed out a few weeks ago, but this one's a little less ovoid and looks like it might even be more comfortable.

Like its ErgoChair counterpart, the BalanceBall chair is doctor-designed, put together by Dr. Randy Weinzoff who extols its virtues, claiming it improves spinal alignment and strengthens core muscles. Never mind all that guff, we just think its bouncy ball keeps your butt from aching after sitting there all day long. If it really can get rid of the dreaded fanny fatigue, its $80 price might be a small price to pay. — Charlie White
