This chair is developed by a chiropractor to help relieve back pain that comes from sitting at a desk for too many hours. It works by stimulating the same core muscles as used in a balance ball workout routine. Keeping these muscles moving helps to keep them from tightening and cramping up, so you don’t get lower back pain.

This means that while you are sitting at your chair you are strengthening your core muscles (those that help support your back), and it keeps your spine in a neutral aligned position (so you don’t put any extra pressure on it).

A nice thing about this chair is that during your break you can also remove the balance ball to do some workouts or stretches.

Note that you can get some of the benefits of sitting on this chair fro sitting on a balance ball (such as the shock absorbing and strengthening). So if you have a balance ball sit on the for a while (or go into a sports store and sit on theirs) and see how you like it before ordering one.

Also keep in mind that this isn’t designed for tall people (the instructions say it’s suitable for people 5′ to 5′11″ tall), so if you are over 6 feet you are out of luck. I’m short so I have no problems
