Micro Stool with hand operated adjustment from 18-1/2" to 26" seat height. This stool incorporates an adjustable wrap-around armrest that contours the body. The armrest is adjustable up and down, in or out, and can swing out of the way when not needed. The stool is completely adjustable with seat tilt and backrest re-positioning at a touch of a lever. The Waterfall seat design relieves pressure on your femoral arteries and the lumbar support aids in correct posture.
