The 503 Soft Props Sofa is an innovatively developed system. It is generated from a nucleus of two modules that can be combined together to create a galaxy of configurations, distinctive both for independence and versatility. The visible tube outlines the perimeter of the seats, creating a protective boundary, which defines space within space; some outer sections of the tube are covered with polyurethane foam, with an aesthetic as well as practical function. The individual modules come together naturally to compose the classic two-seater sofa, an island, a chaise longue or even a bed. The system is completed by low side tables, with or without a drawer, to be joined to the padded elements, and by a separate side table, in different finishes.
