A nice, bouncy, ball office chair. What’s not to like? It’s comfortable, good for posture and so on right?
Well, after digging into this argument quite a bit we found it’s quite possible that there is no such thing as an ergonomic ball chair as this article at ergobuyer.com seems to hint.
It may well be that any exercise ball chair benefits are canceled out in other ways, without even taking into consideration the chance of cracking your head open.
I hate to say this because I absolutely love exercise balls for… well… exercise, and would encourage you to buy a good quality ball. But be careful if you do decide on using one to sit on, the inherent instability can become more of a danger than benefit.
