A piece of furniture, in particular in the form of a piece of display furniture and preferably in the form of a piece of display furniture for displaying goods, further preferably a piece of modular-construction furniture in the form of a rack or cabinet, comprising a plurality of furniture elements, designed preferably as display-furniture elements, in the form of surface-area elements (1, 2) and connecting elements (4), it being possible for the latter to be fitted on narrow sides of the surface-area elements (1, 2), wherein the connection on the narrow sides, it being possible for said connection to be released without the use of tools, takes place via a tongue structure which can be introduced into a groove structure, preferably via a tongue which can be introduced into a groove or via a multiple tongue, designed at least in the form of a double tongue, which can be introduced into a multiple groove, designed at least in the form of a double groove, and wherein the furniture elements (1, 2, 4) are secured via the groove/tongue connection in a direction transverse to the surface-area extent of the surface-area element (1, 2) and, in addition, counter to the direction of introduction via the interaction of at least one magnet (6), arranged on one furniture element, and of a further magnetically attractable part, arranged on the adjacent furniture element, such that two surface-area elements (2, 1) which are arranged one beside the other or directly at a corner are connected via just one connecting element (4).

A modular frame for seats or furnishing elements provided with a supporting surface includes a plurality of section bars that are adapted to be rigidly constrained to one another so as to define the frame of the supporting surface. The cross section of the section bars is at least partially hollow and substantially triangular and is provided with an opening configured to allow a conveniently shaped terminal part of fixing elements to be longitudinally inserted in the section bar in order to join at least two section bars.

In a first aspect of the invention, this is achieved by a joining system for furniture parts comprising female coupling recess formed in a first furniture part, a male coupling tongue projecting from an adjoining second furniture part, said female coupling recess being adapted to receive the male coupling tongue, said male coupling tongue comprising a first locking element configured for a snap joint interlocking engagement with a matching second locking element in said female coupling recess, the male coupling tongue being configured to be more flexible than the female coupling recess. The joining system comprises an upper guiding surface arranged on a first side of the female coupling recess on the first furniture part, forming an essentially non-resilient guide for the male coupling tongue upon insertion thereof, limiting movement of said male coupling tongue in a direction towards said first side of the female coupling recess. The joining system comprises a lower guiding surface arranged on a second side of the female coupling recess on the first furniture part, located opposite to said first side thereof, said lower guiding surface is configured to force the male coupling tongue to resiliently deflect whilst in engagement with said upper guiding surface upon further insertion thereof in a deflection movement towards said first side of the female coupling recess, until the first locking element of the male coupling tongue snaps together with the matching second locking element of the female coupling recess.

The invention relates to a piece of furniture made from a plurality of interconnectable planar elements (1, 2), in particular designed as a piece of children's furniture, such as a play house, wherein at least two of the adjacent planar elements (1, 2) are connectable by at least one plug connection, and wherein said plug connection is formed by a protrusion (3) which is formed on the end face of a first planar element (1) and which has an opening (4) extending crosswise to the flat side of the planar element (1), a recess (5) in a second planar element (2) into which the protrusion (3) of the first planar element (1) is insertable, and a securing element (6) which is interlockingly insertable into the opening (4) of the protrusion (3).
