Movin' Sit Jr. is an inflatable dynamic air cushion which activates intrinsic trunk muscles to support the spine. It is great for kids with poor posture and those who have trouble sitting still. It can also be used upright in any chair as a back support or on the floor. Adjust inflation to comfort level.

The child size version the Movin' Sit Jr. is 11" X 11" and fits perfectly in most primary school chairs.
