How does it work exactly... besides you sit on it... I know.
I've seen a few friends convert over to these for office chairs and I just don't get how it would be comfortable, and well basically how you don't end up flat on your back or face stretching out or something.
If it helps with backpain, and gives you a slight ab work out during the day might be worth checking out. I've been more than a little lax on my workout routine with all the hours im clocking at my desk.
