Expandable/convertible sofa chair

Abstract

An expandable and convertible sofa chair consisting of a base, backrest, two armrests, four small corner cushions, four long edge cushions, centre cushion, two straight connector cushions, two L shaped connector cushions, four feet, four decorative front/back side plates, tabletop plate, centre support board, and four locking mechanisms. The base is a hollowed out square box with a bottom and thick walls that house several cavities symmetrically aligned to mate with the parts that have extruding prongs. When two units are placed side by side the four small corner cushions are removed and replaced with two connector cushions twice the size. The armrests of the touching walls are replaced with long edge cushions and all are locked into place by a locking mechanism at the bottom of the base walls, creating a loveseat. Repeating this procedure creates several different styles, shapes and sizes of furnishings.
