Should I choose a drafting stool with or without a foot ring?

For any situation where the seat will be elevated above standard desk height (above 18"–20" seat height), a foot ring is strongly recommended. Without foot support, dangling legs restrict blood circulation, add pressure to the underside of the thighs, and lead to fatigue within 30–45 minutes. A foot ring positions the feet at a natural angle that takes pressure off the legs. Backless stools used for short-duration standing-height tasks can sometimes work without a ring, but extended use always benefits from one. OfficeFurniture2go.com — call 1-800-460-0858.
