Office Chair - IN 01 | Wilkhahn

The IN office task chair stands apart for its athletic design, use of innovative materials and processes plus its exceptional three-dimensional flexibility. To make offices more motion-driven spaces the chair’s patented Trimension© technology allows forwards and backward tilts, as well as rotational movements. Leading experts worldwide consider these to be important factors in ensuring people stay healthy and productive. The concept encourages changes in posture. It’s been implemented in an especially compact and affordable way in order to tap into a broader range of projects. After its launch over a year ago, the chair’s now debuting at Orgatec with a white through-dyed seat and back element for the first time.

The engineers and designers developed several technological strokes of genius for IN which interact perfectly. The two swivel arms are part of the 3D synchronous-adjustment mechanism and have a direct impact on the spring in the middle whose counter pressure can be adjusted by turning a knob. With a forward tilt that can be activated, the upshot is a huge range of motion in all directions. The highly flexible and supportive seat shell and back are connected with the mechanism via “hip” and “knee” joints and help the body maintain its center of gravity. This high-tech item is made as one single piece using the two-component technology that’s customary in the automotive industry. Finally, the cover on the backrest, made of 3D Formstrick (form-fit knit), delivers ideal support. This technology is used in developing trainers in order to integrate different strengths and thicknesses into the material directly. The combination of these features adds up to a remarkably dynamic and comfortable experience. Only the slightest shifts in weight are required to produce three-dimensional movements where the chair follows the body like a second skin.

Form Meets Function

There’s a good reason why IN’s design mirrors the high-tech concepts applied in amateur sports. Because the materials and manufacturing methods also define the athletic-dynamic look. The backrest frame with its “broad shoulders” and “small waist” merges fluidly with the shape of the seat shell. The lumbar support incorporated in the backrest cover is distinctive and the two swivel arms with the accentuated Trimension joints define the look of the chair from the rear. The design of the chair’s lines, edges, and finishes is extremely precise. The craftsmanship and the die-cast aluminum synchro-adjustment mechanism suggest hard-wearing, superior quality. The color concept for the back and aluminum frames underscores the fresh, athletic image, which is also boosted by the new white backrest elements.

Feature Range

The list of options includes everything required and ranges from 3D armrests, height-adjustable lumbar support to the patented seat-depth extension. Alternatively, the backrest cover is offered as a double-ply version with added foam. The covers on the seat cushion also come in the new, especially hard-wearing Racer fabric, in form-fit knit to match the back and in selected fabrics from the Wilkhahn collection. Innovative development, an integrated design concept, and a multipurpose chair for nearly all body sizes and weights (45 to 140 kilos) have a positive impact on the cost.
