What is the best seat height for keyboarding?
A. It is most important that seat height should allow the upper body postures described in #7, #8, and #9. This upper body posture is most responsible for reducing risk of injury. Once this is accomplished, the feet should be flat on the floor. If the resulting seat height prevents the feet from resting flat on the floor, a foot rest is necessary. Even a phone book can serve as an inexpensive solution. This should allow the lower legs to be vertical and thighs horizontal.
