556 Sengu is a modular sofa by Patricia Urquiola for Cassina. The structure composed of a belted steel frame elegantly finished with two wooden beams in black stained oak or Canaletto walnut and cushions with 100% recycled fiber, made from PET mainly recovered from the sea, has been incorporated in the padding of the cushions and upholstered in fabric or leather.Sengu is a modular sofa characterized by plentiful and enveloping cushions emphasized by the wooden beams of the base. Increased ergonomics thanks to the soft fold of the backrest and armrests with external quilting. Evidently Japanese inspiration, a recurring theme in Cassina products, especially in those of Charlotte Perriand. Patricia Urquiola with this sofa designs sofa modules that stand out for the variety of different compositions that can be created, never conventional, and with a highly contemporary style. The natural colors are enhanced by the quality of the materials used: oak or Canaletto walnut wood for the base mixed with the cushions upholstered with sought-after fabrics. Sengu is a sofa designed to rediscover conviviality thanks to open and generous shapes. You can create refined combinations with the original 557 Sengu coffee table from the same collection.
