ON is the first task chair that enables perfect, three-dimensionally supported sitting thanks to a new type of synchronously supporting 3D kinematics - Trimension. In today's hectic office environment, we all spend a lot of time hunched over at our desks. Strangely, we opt for a comfortable posture despite the negative effects on our bodies. However, what the human body actually needs is frequent and varied movement. Wilkhahn has understood this important principle of ergonomics and has therefore developed Trimension® for the ergonomic ON chair. This unique, tested function is a patented technology for three-dimensional, synchronized dynamic sitting. Trimension® not only promotes forward, backward and sideways movements, but also the rotation of the pelvis - which is so important for the stability of the spine. Two separately movable swivel plates, just like two thighs, form the core of the technology. Even minimal shifts in weight are converted into movement. The position of the pivot points and their mode of operation correspond exactly to those of the knee and hip joints. As a result, the body's balance is perfectly maintained - regardless of posture and movement. This new dimension of sitting quickly becomes a matter of course. Back pain is effectively prevented and the metabolism, muscles and joints are stimulated.
