Office swivel chair Wilkhahn

ON is the first swivel chair that enables perfect, three-dimensionally supported sitting thanks to a new type of synchronously supporting 3-D kinematics - Trimension.

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.
