This is an LC2 petit modele 3-seater sofa, designed by Le Corbusier, Pierre Jeanneret, and Charlotte Perriand. This example was produced circa 2006 by Cassina. It was purchased by a Swiss insurance company and was seemingly only very lightly used, as it shows only minimal wear from use. This LC2 was specified in classic black leather and was likely a more premium leather, as the feel is much nicer than Cassina's typical leather. The sofa's chromed steel frame presents well and shines beautifully. This example is signed and engraved with Cassina Labels. It also retains original labels underneath at shown. See photos for condition. This one actually still has its original brochure as well from Cassina.   

The sofa measures 71 inches long by 26.5 inches tall and 27.5 inches deep.
