The DU 30 armchair has a shaped single shell in steel mesh with moulded polyurethane foam padding. Legs in bent and welded iron tubing with a textured, wrinkled black finish (BLACK RAL 9005). Equipped with a lower ‘backbone’, the shell is directly screwed to each pair of legs. The padding is in moulded polyurethane foam and the upholstery is in Pelle Frau® leather, distinctive for its central stitching which begins at the bottom of the backrest, where gentle folds are formed, and continues right along the seat. The front is embellished with hand stitching.
