Swivel chair ON 174/7 from Wilkhahn

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, synchronously adapted dynamic sitting. The innovative mechanism with independently movable swivel arms, the three-dimensionally movable Flexframe consisting of a torsionally elastic, slim upholstered seat shell and an elastic backrest frame as well as the Fiberflex backrest cover ensure outstanding sitting comfort.
