560 Back-Wing is a chair designed by Patricia Urquiola for the Cassina brand. The sensoriality of the skin is combined with the essence of wood for a seat with a strong impact design.The structure of the chair is in solid natural ash wood, stained oak or stained black. Large sections of the legs and crosspieces highlight its solid shape. The leather upholstery lies gently and folds on the structure giving the chair a great comfort. The Back-Wing upholstery is elegantly finished, with no visible seams, and with a leather cord that delimits and precisely defines the perimeter profile of the chair.
