IN Ergonomic Swivel Office Chair by Wilkhahn offers dynamic comfort and ergonomic design for maximum freedom of movement and healthy working. The patented Trimension® kinematics with two independently moving rocker arms, two spherical joints at hip height, and two push joints at the knee axis ensure maximum three-dimensional dynamics while sitting, reflecting the fluid movement of walking without causing fatigue.Activates the entire body, from ankles to cervical spine, preventing musculoskeletal disorders, stimulating metabolism, and increasing performance.The synergy of direct drive, high-tech torsion-resistant backrest element, and 3D molded knit backrest cover creates extraordinary dynamism and incomparable seating comfort.Even the smallest weight shifts lead to fluid posture changes, perceived as very natural and comfortable. The interaction between person and chair is completely intuitive, making mobility a versatile and frequently used feature.The ingeniously simple implementation of Trimension® kinematics ensures a sporty appearance. In addition to impeccable workmanship and high-quality finish of surfaces and materials, which meet the strictest standards, indestructibility is guaranteed, with at least a 5-year warranty.New Look: IN with New Molded KnitThe new 'ReForm' molded knit fabric, available in ten colors, gives IN a very attractive and sustainable facelift.
