A balance or wobble cushion with two textured sides, one with a soft spiky surface for standing and the other with small dimples which are comfortable, but still effective, for sitting. It can be used to improve balance and coordination whilst standing. The disc is particularly effective for working on core and lower body strength and it is also recommended for use in stabilising and strengthening muscles and joints, especially ankles and knees. Placing it on a chair and sitting on the small dimpled side can improve posture, prevent slouching, strengthen core muscles and help reduce back pain. It has a wipe clean surface and is easy to inflate. Includes pump.
