About ON chair from 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.
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.
- ON thus creates significantly greater and more natural range of motion in the lateral tilt and rotation of the pelvis and shoulders.
- ON stimulates metabolism, improves spinal elasticity and muscle coordination, and increases activity without tiring the body.
- The innovative mechanism with independently movable swivel arms, the three-dimensionally movable flexframe consisting of a torsionally flexible, slim upholstered seat shell and elastic back frame, as well as the backrest covering made of Fiberflex ensure excellent seating comfort.
- A wide range of models and combinationsleave nothing to be desired in terms of function and design. They ensure seating solutions from a single mold and from a single source.

Design Story
Founded in 1907 near Hanover, Wilkhahn began as a traditional furniture manufacturer before evolving into a pioneer of contemporary workplace design. In the decades following World War II, the company embraced modernism and developed a philosophy centered around functionality, movement, and long term quality.
Wilkhahn became especially influential through its focus on ergonomics and dynamic sitting. Rather than designing static office chairs, the company explored how furniture could support natural movement and improve wellbeing during long hours of work. This approach led to innovations like the Wilkhahn ON Chair, whose three dimensional movement system helped redefine modern ergonomic seating.
Unlike many corporate furniture brands, Wilkhahn placed equal importance on engineering and visual restraint. Its furniture often features clean architectural lines, premium materials, and subtle detailing that reflects a distinctly German approach to design: precise, intelligent, and understated.
Today, Wilkhahn furniture is found in executive offices, creative workspaces, and institutions around the world. The brand remains closely associated with the evolution of the modern workplace, where comfort, movement, and design are increasingly seen as inseparable.
