Best price and nice product
I was looking for ball parking system such as ball chair, ball base, and ball ring. This base is little bigger for my medium size fitness ball. But, the price was the best online. It does the job to park the ball, and so light to carry around, but steady on especially on carpet. I like the parked but still flexible ball's movement so that I can easily do the exercise on the ball sitting on the base. It hardly falls out of the base when you do exercise, and sits on it when it's supposed to be a chair.
