Its iconic design indicates as soon as you look at it that something very special is hidden in the stool that can be felt immediately when you sit down. Its unique technology of free-fl oating compression and tension springs convey an unprecedented, almost fl oating sitting experience that lets you swing in 4 dimensions. 

This activates the back muscles while sitting and automatically ensures an upright sitting position. The fact that the whole thing is visibly fun and adds the highest fun factor to healthy sitting is just a positive side effect.
