Meet the Swopper Chair: an ergonomic chair that promotes better posture and makes your core stronger. It lets you move in all directions while you sit. By keeping balance on the sprung seat, you will keep your body in motion. Since the chair tilts towards your working surface, you don’t need to hunch your back.
The Swopper Chair moves your joints and keeps your muscles active. It also relieves pressure on the discs of your spine. The height and stem tension are adjustable. The bad news? These chairs are not cheap.
