The Wilkhahn brand of professional furniture seeks to bring movement into office spaces. Psychologists, physiotherapists and orthopaedists agree that movement is a vital need. There is more at stake than back pain, the proper functioning of the intervertebral discs and the healthy strain on various joints. Thus, the Wilkhahn team of engineers and designers has taken a new step with the IN chair by developing a more accessible version of the Trimension system, designed specifically for administrative departments. It combines a highly advanced 3D permanent contact system with a high level of comfort. The result of IN is well-being, concentration, a relaxed posture conducive to efficiency and freedom of movement in this new office chair from Wilkhahn.
