Worthwhile: Sit, Stay
(Worthwhile, April 01, 2006)
At last, we actually have a choice of what to sit on. Chair design has improved so dramatically over the past decade with form + function going to new heights. Those heavy leather executive chairs are so yesterday; in their place are sleek, supporting, adjustable models.
Properly adjusted seat height helps distribute body weight. Position your seat height to allow a knee angle of at least 90 degrees with your feet fully supported by the floor or a footrest.
