Sitting on a SpinaliS chair seems quite similar to recreation
SpinaliS is significantly different from the chairs that I have used so far. SpinaliS requires active sitting and prevents improper posture while sitting. Sitting on a SpinaliS seems quite similar to recreation: the back muscles are constantly sitting slightly tense and active, movement is easier. After sitting for a long time I feel like I do after moderate recreation and not stiff and tired like after sitting in a long forced position. You need some time to get used to sitting on the SpinaliS, but you are aware of its positives very quickly.
SpinaliS is a revolutionary, high-quality product, which can significantly reduce the effects of extensive sitting. SpinaliS has improved my quality of life.
