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
The lumbar adjustment enables adjusting the pressure of the backrest in the lower back. Back injuries are one of the most common occupational health problems, so we recommend using a chair that incorporates this type of adjustment that allows us to create a more natural support that follows the curve of our back.
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.
