A composed element, such as a piece of furniture, wherein the composed element comprises at least a rear wall, as well as a number of constructional parts forming a whole in which the rear wall has to be provided. The rear wall forms the rear side of the composed element and includes one or more rear wall parts. The composed element comprises seats for installing at least one of the rear wall parts, which are configured such that the rear wall part can be slid into the seats starting from the rear side of the composed element from a position differing from the final plane in which the rear wall part will be situated in the final condition.

A cabinet structure is provided. The cabinet structure includes two side frames, and at least one vertical sectional bar connecting the side frames via at least two frame elements. The frame elements include first and second frame elements. The first frame element includes a connecting face that has a frontal cavity and a plurality of guide elements. The second frame element includes a receiving face configured to receive the guide elements of the first frame element, and a through hole aligned with the frontal cavity of the first frame. The frame elements also include a securing element configured to be screwed into the frontal cavity via the through hole to forge a secure interlocking fitting of the first and second frame elements.

A corner fitting includes a sleeve body having a hollow inner space and configured to coaxially fit over a pipe member of a predetermined size. An edge of the sleeve body at a second distal end has a corner cut portion, a protruding tab, and two recesses, the protruding tab being diametrically opposed to the corner cut portion in the radial direction of the sleeve body, and the recesses being diametrically opposed to each other in the radial direction of the sleeve body. The corner cut portion is configured and shaped such that the sleeve body fits together with an identical sleeve body on the pipe member of the predetermined size with the corner cut portions of the two sleeve bodies contacting each other and with the pipe being nested between the protruding tabs of the second distal ends of the two sleeve bodies.
