These bed sofas named Sax designed by Rafa Garcia for Sancal. Sax start from three basic principles: essence, austerity and geometry. These designs have been prepared by the blocks with straight and compact central module that combines bold design for the arms. The result is an irresistibly convertible modular. But apart from being a modular composition, it is also an auxiliary bed that can be combined with the poufs, tables and with the optional cushions of the collection.
The mechanism of action is very simple: you only need to lift the seat a bit and pull outwards. These movements expel the brakes that avoid spontaneous movement in the rest position. [Via]
