Title: Gimmick
Review: I am a grad student and spend a lot of time at my desk. I tried this product during finals and it was just as hard on my back as any office chair ever was. It also hurt my hips because there was less give than if it had been placed on the ground. I tried alternating between this chair and other ones to give my back a rest and to try to adjust to hardness of the ball. It continued to pain me, so I returned it. If you're into the idea of sitting on a balance ball to improve your posture or strengthen your core, just get a big ball. This product's height is problematic because it works against all the benefits of sitting on a ball: you don't have to balance yourself and it lifts you too far off the ground (your thighs should be parallel to the ground when you sit but they can't be with this thing). Also, it looks like a cheap commode, which is kind of embarrassing to have in your workspace.
