Funny, I just came up with this idea on my own today, thought I was a genius, and now I see people have been doing it for a long time But I love the freedom of rolling around in front of the PC. I’m 61, in excellent shape, meditate and do yoga everyday; it’s just that I work at my computer, and I have some serious back issues. I plan to give this ball chair a really good try. Already I’m experimenting with how I can stretch back and forward, side to side. This just HAS to be better for my back and my poor posture than that office chair. Thanks for the article.
