At what height should a drafting chair foot ring be set?

The foot ring should be positioned so your feet rest flat on it with your knees bent at roughly 90° and your thighs parallel to the floor. For most users sitting at a 36" counter-height surface, this places the foot ring between 12" and 16" from the floor. On chairs with an adjustable foot ring, set it by loosening the collar, sliding to the correct position, and retightening. If the foot ring is fixed and doesn't match your height, consider a different chair model. OfficeFurniture2go.com stocks adjustable foot ring models — call 1-800-460-0858.
