SpinaliS is an excellent ergonomic solution. In the middle, the riding position, the seat with a spring requires constant adjustment of vertebral muscles and maintaining balance and thus upright posture with both continuous vertebral muscle activity. Sitting in the rear position (resting position), provides the best ergonomic solution to sit.

From personal experience I can confirm the great advantages of SpinaliS over other chairs. SpinaliS chairs work. For thirty years I have been suffering from pain in my lower back, and over the past 12 years I have had three strong attacks of lumbo ishialgia I have dealt with it by physical therapy and regular exercise. After my last attack, six months ago, I decide to have an operation on my intervertebral disks.

I have been using it for 5 months now I do not get back pain, which I had previously after prolonged sitting. Therefore I can recommend SpinaliS chair to anyone who suffers from pain in his lower back, and prevention to anyone in business who is exposed to prolonged sitting.
