At the core of a HÃG chair our unique Balanced Movement Mechanism works to intuitively keep you in balanced motion. A HÃG chair inspires you to vary your postures. A centrally placed tilting point intuitively keeps you in balanced and continuous motion. As the seat and the backrest are linked together, the seat front rises when you lean backwards and stimulates your ankle movement. The seat lowers as you lean forward to work. Sitting in a HÃG SoFi creates a sense of privacy as well as space for collaboration. At the core the Balanced Movement Mechanism answers to your slightest move and keeps you in balanced and continuous motion. The innovative HÃG Slide Back features a comfortable armrest. Levers and handles are intuitively placed, easy to find and to adjust.
