      Great purchase, arrived in timely manner and easy to put together. Chair alleviates pain from sitting in a desk all day. Excellent purchase, ball has to be refilled but not a major issue.

      The ball is not secure in the seat tray and if I sit back on the ball my feet are way off of the floor. Perhaps this chair is for a taller person. I will request to return it.

      This is a great desk chair since it has the wheels to roll in out of your desk. It is also nice to get the core strengthening while you are working on the computer. I really am pleased with this purchase!

      my favorite chair if I have to be sitting upright. I got the rolling casters for this chair. Staples has then routinely for not much. That way, doing “core” pelvic tilts to relax don’t have to quit @ the hip bone. You can curl & uncurl to your heart’s content, chin to heel, making it easier to prove to yourself that the work you’re doing is not destroying the rest of your life.
