Review on Pharmedoc Exercise Ball Chair With Back Support For Home And Office W/Exercise Yoga Balance Ball, Pump, Removable Back & Lockable Wheels by Sean Powers

I have had this chair for a little over a year. Almost immediately the back "support” gave out and now it’s just a ball on wheels.The ball is still working well. It slowly loses air over weeks, but I keep a pump close by and it’s nothing considerable at once.The "chair” is really just a base with wheels. Almost immediately upon trying to lean back I flew backwards onto the floor. I heard a pop and the back support just wobbles now.Careful leaning back even without the base. I have made a fool of myself and went flying backwards onto the floor.I like it simply because having just a ball on the floor didn’t work. They kept getting punctured. The flat base doesn’t work because I need to move around. So, a base with wheels will do. I guess.I would love to find a ball with a truly supportive back and wheels!
