Absolute comfort, thanks to its generous volumes, and a delicate design with simple geometries, characterize this sofa designed to rediscover a convivial dimension thanks to its open shapes. Inspired by the Orient, a recurring theme in the Cassina Collections and expressed in particular in Charlotte Perriand’s work, Sengu Sofa stands out for its different and never conventional compositions, all with natural materials and colors. Its structure, composed of a belted steel frame elegantly finished with two wooden beams, evokes Japanese memories; the sofa’s ergonomics are heightened by the soft fold of the backrests and armrests that are characterized by external quilting. This same detail is also repeated on the back cushions that complete the sofa. Thanks to the study carried out by Cassina LAB, a collaboration between the Cassina Research and Development Centre and Polidesign at the Milan Polytechnic, a 100% recycled fiber, made from PET mainly recovered from the sea, has been incorporated in the padding of the cushions.
