Movin SitThe MOVIN'SIT is a wedge-shaped cushion which may be inflated slightly. The spine should have a natural S-curve, which is often flattened out when seated on normal chairs, or with habitual poor posture. The Movin'Sit tips the pelvis slightly, helping the spine maintain its correct curve. Because the wedge is slightly inflated, it is therefore unstable - just like the ball. So it gives almost any chair many of the benefits of active or dynamic sitting. If you already have a good natural S-curve in your spine, the DiscoSit might be more appropriate.
The Movin'Sit Air Cushion is an inflatable, dynamic cushion which activates intrinsic trunk muscles to support the spine.
It is contoured to support the thighs and buttocks to maximize comfort and stability. It can also be used upright in any chair as a back support or on the floor
