An improved joint is provided for modular furniture. The joint includes a locking tab and slot. The tab is held in the slot such that the tab cannot be moved out of a locking section of the slot without elastically bending the tabbed panel to prevent inadvertent disassembly of the item of furniture. The tab and slot configuration may also provide increased stiffness and rigidity to the piece of furniture while allowing the piece of furniture to be assembled without fasteners such as screws or nails.

A furniture unit includes at least one substrate having an upper surface, a lower surface, a proximal peripheral surface, a distal peripheral surface, a first seam, and a second seam. The lower surface is opposite the upper surface. The proximal peripheral surface extends from the upper surface to the lower surface. The distal peripheral surface is opposite the proximal peripheral surface and extends from the upper surface to the lower surface. The second seam is spaced apart from the first seam. The first and second seams extend in a direction parallel to the proximal peripheral surface. The proximal peripheral surface engages the lower surface such that the substrate defines a first hollow support.

Load-bearing furniture (such as beds, tables, desks, benches, and the like) made from lightweight, foldable material, comprised of base supports with beveled crenellations along certain top edges of the supports, designed to securely receive beams formed in the shape of flanged triangular prisms, said beams optionally featuring ventilation holes to facilitate air circulation through beam cavities.

A support assembly for easy assembly and reliable operation is disclosed. Support assembly includes a plurality of support members, with at least one support member including connecting slot and at least one other support member having a complementary slot. Each slot features at least two tapered faces or walls to provide a wedge effect that ensures a tight reliable fit when the two members are fitted together.

A cabinet includes a plurality of vertically spaced-apart shelves adapted to hold product for display in a retail location. The cabinet is formed from a flat blank which is folded to form the cabinet. The cabinet further includes an interior structure to provide strength and rigidity. Multiple cabinets can be coupled together in a system to create multiple configuration displays.

A structural system and method of assembly comprising structural members with slots, and interior structural members. Specific structural members are sequentially interconnected in rigid alignment. A first structural member is positioned with two upward facing slots. Additional structural members are added by engaging downward facing slots of the additional structure members with upward facing slots of the prior structural member. The structural members further include engagement features in cooperating slots. A protruding features engages a recess to retain the engaged structural members. The features may be a partial sphere and a matching recess which may be disassembly, or a tapered protrusion having a squared-off rear edge which resists disassembly, or one of a variety of shapes.
