Extremely rare 932 'Quartet' sofa designed by architect Mario Bellini and manufactured by Cassina in Italy in 1964. Very early model made up of five separate pieces. It's quite challenging to come across one in this large and impressive size. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
