A furniture and display system (1) having right side structure (2) and left side structure (1) that may be configured to be used as a chair or display in a retail setting. A rear panel (4, 10) of at least one of the two side structures has two panels which form a space to allow the rear panel of a corresponding side structure to be inserted therein to form an elongated shelf or seat. The design of the two pieces allows the side structures to be nested and/or placed together in multiple configurations.
