Abstract: Interfitting furniture formed by the coupling together of a least two elementary pieces of furniture, each of which comprises a supporting portion and all the supporting portions are at the same height above floor level and each of them is formed by a plurality of elongated members, each of which defines with the adjacent ones a space which is substantially occupied by the corresponding elongated members of the supporting portion of other elementary pieces of furniture. Each of the elementary pieces, when slid apart for separate use, provides a furniture article having the same type of functionality as the more massive composite furniture article of which it, when reversibly assembled with one or more like or similar elementary pieces, forms a part.
