IN

The IN range features the patented Trimension® kinematics, which allow the body to experience fluid, three-dimensional movement. With two independently moving swivel arms, hip-level ball joints, and thrust joints at the knee axis, this technology mimics the natural rhythm of walking—activating the body without causing fatigue.

Far more than a chair for the back and joints, IN stimulates the entire organism from the ankles up to the cervical spine. This activation not only prevents musculoskeletal disorders but also boosts metabolism, reduces stress, and enhances overall productivity—an essential element for modern workplace wellbeing. The synergy of direct transmission, a torsionally flexible high-tech seat-back element, and the innovative 3D-Formstrick knit creates outstanding comfort and dynamic support. Even the smallest shifts in weight translate into smooth, intuitive posture changes, ensuring mobility feels natural and effortless.

With impeccable craftsmanship, premium materials, and a distinctive dynamic design, the IN chair sets new standards in both performance and aesthetics. Built for longevity, it comes with a warranty of at least five years, reflecting Wilkhahn’s commitment to durability and quality.
