Office chair ON


Range 170

Are you still sitting still? Then it’s time to switch to the ergonomic office chair ON®. Because it was the world’s first office chair with Trimension® technology – encouraging natural posture and enabling three-dimensional movement. It is good for body, soul and mind. What’s more, it’s recommended by leading health experts and has received many prestigious design awards. Three-dimensional movement. While seated.

In today’s busy office environment we all spend long periods of time in hunched positions at our desks. Bizarrely, despite being bad for our bodies we choose to adopt a lazy posture. What the human body actually requires is frequent and a varied range of movements. Wilkhahn understands this key principal of ergonomics which is why we have developed Trimension® for the ergonomic ON chair. This unique tested feature is a patented technology for three dimensional, synchro-adjusted dynamic seating.

Trimension® doesn’t just encourage forwards, backwards and sideways movements, but the pelvis to rotate too – which is so important for the spine’s stability. Two separately moveable swing plates, just like two thighs, lie at the core of the technology. Minimal shifts in weight are already translated into movement. The position of the pivotal points and the way they work are exactly like knee and hip joints. As a result, the body’s equilibrium remains in perfect balance – no matter what posture it adopts or the way it moves. This new dimension in seating quickly becomes something that’s -taken for granted. Backache is effectively prevented and the metabolism, muscles and joints are stimulated.

The ON® product family offers three backrest heights, three types of armrests, and three types of upholstery. In terms of function and design, ON® covers all requirements. All task-chair and conference models, plus four-legged and cantilever chairs in attractive finishes and covers, tick all the boxes in terms of function and design. Simply seamless solutions.

Three backrest heights (medium, high, high with headrest) and three types of upholstery offer plenty of scope for design to achieve those subtle differences.
