In order to make the DU armchair as ergonomic as possible, the contours of a human body were measured precisely using a 3D scanner. The readings served as the basis for the chair design so that the backrest, for example, curves to fit one’s body snugly. This classic-looking chair is made of walnut. The seat consists of a metal construction combined with leather, a special stitching technique has been used to conceal the seam. Legs and seat are screwed together to provide the necessary stability.
