After five years of development, ON sets a new milestone in dynamic seating. At the core lies Trimension®, a three-dimensional supporting kinematics that precisely follows the positions of and scope of movement in the knee and hip joints. It activates a whole range of completely natural and relaxed movements. The new dimension is a perceptible part of the design and has been implemented in the easiest way conceivable. The chair's visual form follows intuitive function. By pressing two buttons to rapidly adjust the counter pressure, ON is immediately ready to go. Three backrest heights and types of upholstery ensure a varied range of models.
