Synchron Plus Mechanism

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.

4D Armrests

4D Armrests

This type of armrest can only be found in high-end ergonomic chairs, allowing total adjustment of the height, width, angle and depth.

Adjustable seat

Adjustable seat

This function enables adjusting the depth of the seat adapting it to the length of each user´s legs, thereby obtaining a more comfortable and healthy position while we are working. This type of mechanism is normally used in high-end ergonomic chairs.

Mesh

Mesh

Mesh chairs are breathable, highly recommended in warm environments. There is a trend in the office industry towards this type of chair as they do not build up dust or dirt and are easier to clean than traditional chairs.

Lumbar arch support

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.
