Sitting all day killing your back? The SISSEL Sitfit cushion turns sitting into a mini-workout. It's an air-filled disc (33cm diameter) that makes you engage your core and back muscles to stay balanced, which promotes better posture and can reduce back pain. You can adjust the firmness by adding or releasing air with a pump (not included, but a standard ball pump tip works). It's not just for sitting—flip it over and use it as a wobble board for foot and ankle exercises! It's made from durable, phthalate-free material, supports up to 304 lbs, and comes with an exercise poster for ideas. Perfect for the office, home, or even for kids who need to move a bit while focusing. A simple tool for a healthier back.
