The backrest is height-adjustable by means of a sliding system. This type of mechanism is only found in high-end ergonomic chairs. By adjusting the height of the backrest, we can adapt it to the curvature of the back by reducing the stress on the lumbar and shoulder area.
Synchron Plus Mechanism
This type of mechanism is the most advanced on the market and recommended by all ergonomics specialists. The seat and backrest synchronously and automatically adapt to our movements. Therefore, when the backrest is tilted forwards or backwards, the seat tilt is also automatically adjusted at the same time, resulting in a dynamic and perfect posture. An anti-return safety system prevents hurting the spine.

Lumbar arch support
