Reduces pressure on the intervertebral disc
The intervertebral discs serve as shock absorbers placed between the vertebrae. In order to maintain a healthy spine, we need to maintain their elasticity. The pressure on these discs in a horizontal position is approx. 50 lb, in an upright position around 200 lb, and when sitting on an ordinary chair with a fixed seat, it increases dramatically. While sitting on SpinaliS chairs this pressure is reduced due to constant movement and position changes. On the other hand, sitting on a regular or ergonomic office chair with a fixed seat and having a poor posture leads to a high burden on the discs. The gelatinous nucleus pulposus gradually moves back bending towards the spinal cord, which is referred to as herniated disc or disc herniation.
