Traditional office chairs may be comfortable but they are not good for your health. If you spend hours in them every day, you are going to develop serious health conditions. The Core Muscle Workout Stool is different. This unique piece spins and moves on its domed base to get you to use abs, legs, and back muscles. You get to maintain your stability and posture and get a low-impact core workout.
As long as you weigh under 300 lbs, this piece should work for you. Its position can be adjusted from 22.5″ to 31″. You can get one for under $200.
