Go to an office supply store and try out chairs that fit you! There are so many different styles for different body types. Some have wider bases and are more comfortable for some. For good support, go for a 5 caster bottom. Make sure you try the height adjustmentsto make sure you can actually make them go up and down. Some of the chairs are much more difficult to adjust. Check out the chair back to make sure it can be properly adjusted for your back. :lol:
I think there was an article about ergonomics recently in the newsletter. I am sure I read some of these tips there and that there was more advice that I forgot! :?
