The ON Chair, which is a reflection of the German design school, defies the intense work tempo by keeping the user away from anatomical problems while sitting in the desired position, thanks to the three-way stretching and one-button locking features offered by the trimension technology. Attracting attention with its plain and strong design language, ON Chair office chair is the “comfort” point of busy workers in crowded offices. The armrests, whose height can be changed with a single button, also have contact surfaces that can be changed in depth and angle. It is designed for six different positions that can be locked after the back part is adjusted.
