One of the most influential of 20th century architects, Chareli-Edouard Jeanneret, who chose to be know as "Le Corbusier”, was also responsible for some of the Modern Movements best-known furniture. In this category are his classics known as LC2 Sofa and Loveseat and the LC3 "grand confort” Sofa and Loveseat. We use high gauge tubular stainless steel on each frame. The frame is polished to a mirror-like finish with mitered frame corners ground to a soft radius. Besides the polished frame, we also offer 4 colors of metallic powder coated finishes, or choose your own! We use top-grain, aniline-dyed leather on all visible cushion surfaces. Inside each cushion is high density, HR (High Resilient), Multi-Density polyurethane foam surrounded by Dacron batting. On the LC2 seat cushion, there is a layer of goose down/feathers on the seat top. On the LC3, the seat cushion has an extra layer of Dacron fiberfill. The LC3-relaxed uses both foam and goose down/feathers on the side and seat cushions for the most comfortable of the Cassina style chair.
