I just purchased this chair to replace a balance ball that i have been using as a desk chair for about a year. Frankly, i prefer the real thing. The ball without the chair 'frame' gives me more mobility, is more comfortable and is cheaper. For my money, i'd skip the frills and just sit on your ball. One caution, you do need to be mindful when you get up and down as you seat can/will fly out from under you at times. Makes life interesting! ( -:
