This desk chair is designed by Sivan, so naturally it has countless benefits for your health—balance, rehabilitation, posture, and spine placement—just to name a few. The base has four rolling wheels, two that are adjustable to fit any person or any desk. Not only can you use this chair to sit upright, but you can also stretch and improve your circulation. Oh, and you can bounce too! Which sure beats sitting stiff as a board all day.
