IN - 184 range

Psychologists, physiotherapists and orthopaedists all agree that physical activity’s vital if we want to stay fit and healthy. But it’s the whole of our body that’s important and not just our backs and joints. Getting enough exercise helps us manage stress, feel happier and be more productive. And productivity is a top priority for corporate healthcare programmes. Wilkhahn has devoted decades to making people less desk-bound.

It all began with a pioneering study entitled "From posture-based to motion-based seating", which led to products that are still considered the best and most attractive office chairs in the world. Recent research highlighting the minimum amount of physical activity required encourages us to continue on this path. And advances in materials and process technology have opened the door to a whole new dimension of dynamic sitting with our patented 3D kinematics called Trimension®. Our engineers and designers have created IN and brought this groundbreaking technology to the back office. Perfectly synchronized 3D dynamics combined with exceptional comfort stimulate the body, increase concentration and make work a relaxing experience.

IN at a glance

IN teaches seating to walk! The patented Trimension® kinematics provide maximum three-dimensional seating dynamics with two independently moving swivel arms, two ball joints at hip level and two thrust joints at the knee axis.

This technology mirrors the fluid motion of walking without causing fatigue. Activation of the entire organism from the ankles to the cervical spine prevents musculoskeletal disorders, stimulates metabolism and increases performance.

The synergy of direct transmission, torsionally flexible high-tech seat back element and back covering made of 3D-Formstrick (form-fit knit) creates remarkable dynamics and unparalleled seating comfort.

Even the smallest shifts in weight lead to fluid changes in posture that are perceived as highly natural and comfortable. The interaction between user and chair is completely intuitive, making mobility a frequently used and versatile characteristic of use.

The ingeniously simple implementation of Trimension® kinematics provides a dynamic appearance.

In addition to the impeccable quality of workmanship and the high-quality surface and material properties, which meet the highest standards, we guarantee their indestructibility and therefore generally provide a warranty of at least 5 years.
