Abstract

An assemblable and disassemblable, convertible sofa characterized by the concealment and, therefore, the visual absence of fasteners after the sofa has been assembled. Where two parts are to be joined, a metallic insert having internal and external threads is inserted into one of the parts to be joined. A screw passes through the other part to be joined and matingly engages the internal threads of the insert. In the assembled condition of the sofa, the arm rests are secured to a base frame by means of fasteners that extend in an outward direction from an internal portion of the base assembly of the sofa. The back wall of the sofa is similarly assembled. A sliding board is mounted on the top wall of the base assembly and is movable between the opened and closed positions of the sofa. In one embodiment of the invention, the sliding board is manually pulled forward from the closed to the open position and also manually reversed, while in an alternative embodiment of the invention, hydraulic means are used to move the sliding board between the opened and closed position.
