Cassina duc three-seater sofa in original burgundy velvet, 1970s design by mario bellini mario bellini's 1976 duc design is based on the combination of cutting-edge materials and innovative structural technology. The distinctive panel structure assembled with zippers was a revolutionary solution for the time. both the panels and cushions are upholstered in smooth burgundy/aubergine velvet with camel/gold trim. The panels are held together with zippers, a characteristic of the entire duc line. The padded cushion covers are removable. one leg features the cassina meda adhesive label. the sofa is solid and stable, still relevant today, and comes in a very rare and elegant color. There is a small hole in the upholstery on the right side (see photo).

His works are permanently exhibited at the moma in new york. dimensions: w x d x h: 248 x 90 x 73 cm weight: 40-80 kg this piece has an attribution mark, i am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
