I really like the idea of the Balance Ball Chair system and even ordered two in the belief that one would solve my husband's back aches from sitting at a painting easel. I only assembled one chair and used it for about three days. While working in my office and rolling between the computer, printer and file cabinet, the cheap plastic on the "legs" collapsed so that the casters ground to halt (scraping my new floor) and I sprawled on the floor. So I'm sending both back. Let me know if you ever decide to make the chair out of something more durable.
I could tell a major difference after only the second day! My posture is so much better, my back is not as stiff, and I can stay active at my desk all day long. Great product!
Today is my second day to use at work. This is such a comfortable chair. I am definitely going to have a good school year now. I am always up and down working in a school office. I am so pleased that I purchased this chair.
I bought this about two weeks ago, I got it delivered very quickly and I am extremely happy with this chair. Its very comfortable and easy to assemble.
I have used the ball chair for the past 5 years as my office chair, and love it. I just gave my original one to a colleague for her home office, and bought myself another one. Neck stiffness while sitting at my desk is but a distant memory...
