cast aluminumpolypropylenepolyurethane

Product Overview:IN office chair by Wilkhahn offers dynamic seating comfort and ergonomic design for maximum freedom of movement and healthy working. 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.Sporty ergonomic office task chair designed for active sitting. 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.Activation of the entire organism from the ankles to the cervical spine prevents musculoskeletal disorders, stimulates metabolism and increases performance.High-quality surface and material properties, which meet the highest standards, with a warranty of at least 5 years.New look: IN with new shape knitThe new “ReForm” shape knit, available in ten colors, gives IN a highly attractive and sustainable “face-lift”. Thanks to the two-tone yarns made from 100% recycled polyester, one or the other color comes to the fore depending on the knitting pattern. The different color zones further emphasize the sporty character of the swivel chair.Available from March 2025Frame: Five-star base made of black through-dyed, fiberglass-reinforced polyamide, optionally of die-cast aluminum, coated, polished or highluster polished.
