Abstract: This modular furniture is formed from components of varying size and configuration which can be connected together to form different furniture combinations. Each component includes two pairs of opposed panels, which are provided with chamfered side edges and adjacent grooves. The panels are interconnected by corner-forming rails having angularly related legs terminating in elongate lips which are received within associated panel grooves to hold the chamfered edges of the panels together in a box-like formation. The legs of the rails provide cooperating outstanding bearing faces spaced from the panels, and adjacent panels of corresponding components are connected by fasteners tending to draw the panels toward each other. The components can be modified to be fitted with individual covers.
