Le Corbusier's LC2 has a look that remains unchanged as its design and production has achieved perfection. The concept of loose cushions moulded by its support system is the main idea behind the Cassina LC2. Its cushions, comprised of a polyurethane core wrapped with polyurethane foam and polyester padding or padding in feather, are held in place by a polished, trivalent steel frame, allowing the loose cushions to combine and form the seating component of the furniture piece.
