Title: plain ball is better
Review: I had this chair but switched to using a plain ball which was more comfortable. The chair and the ball were too short and didn't move easily. When I bought it they just had the black ball option and the whole chair was too small. The "backrest" wasn't doing anything.I ended up buying another (larger) ball. Even though it fit into the chair it was just easier, more comfortable and less hassle using a large ball by itself than using the chair. The plastic is cheap and the wheels don't move. The issue I found with all balls (in or out of a chair frame),is that standard desks can be too high (perhaps more so if you are a short person) and height adjust-ability is very limited with a ball chair. I ended up getting a desk where I could vary the height.
Is the review positive or negative?
