Abstract
Abstract A piece of furniture in which two side walls are joined to respective spaced edges of a back wall extending in a common direction so as to define a channel, and a partition perpendicular to the back and side walls bisects the channel, may constitute a chair for a child when the partition is horizontal to provide a seat, or a table when the piece rests on one of the side walls. Two such pieces can be interengaged to form an approximately cube-shaped hassock if each partition is partly slotted to receive the partition of the other piece.
