The cosy Topstar Sitness High Ron stool brings movement and variety to sitting and standing. It combines sitting, standing and moving in one ergonomic stool. The plastic tyre base allows the Sitness office stool to move thanks to its elasticity and malleability. The back muscles are relieved and mobilised by its height adjustability - your back is exercised while sitting. The intervertebral discs are also relieved, the circulation is stimulated and this can increase the ability to concentrate and the willingness to perform. Whether at work, at home or in the health sector.
