This multi-purpose furniture piece comprising:two rungs having their ends affixed to the free ends of each two legs located at one longitudinal side,a wall rigidly connected to the seat plane and to the rungs so as to extend perpendicular to the seat plane and parallel to the transverse sides thereof substantially intermediate therebetween,and an end plane affixed to a transverse side of the seat plane and/or to the legs located at this transverse side and being of a smaller dimension in the direction of the legs than the length of said legs.

Abstract: A convertible table is comprised of a central planar section and two end sections. The end sections are hingedly secured to the central planar section for rotation thereabout. Each end section has a pair of legs fixedly secured thereto. The legs are not capable of movement with respect to the end sections, but rotate with the end sections.Utilizing the aforementioned approach, a number of table designs are possible. For example, to facilitate folding, the pair of legs attached to one end section may have a greater distance therebetween than does the pair of legs attached to the other end section. In this manner, when the end sections are folded to a position perpendicular to the central planar section, a coffee table, or cocktail table or the like having a lower overall height is formed. The end sections support the central planar section and also form two sides of the table. The legs form the other two sides of the table and may also support the central planar section.
