Review on Improve Posture And Balance With WALIKI Adult Size Stability Chair Ball For School & Office by Ham Channell

First thing you notice is such a strong chemical odor. It does not seem to dissipate over time. So I take it out and try to inflate with the hand pump. That was not working so switched to an electric pool pump. Got it to look round but not fully inflated, still had wrinkles from being folded. Worked for an hour to get more air into it without success. I tried sitting on it. Well it went down to about 10 inches off the ground. I have other exercise balls and this has never been an issue. Disappointing as I liked the 5 legs that keep it sitting where you want it to sit. So this was a failure was wanting it in my home office. I sat it in the garage due to the odor and next time I went out the garage smells toxic. It must go in trash soon.
