Modular system for platform and shelving structures. In an assembled configuration, a module has a central vertical member hingedly-coupled to a second vertical member extending perpendicular to a first side of the central member, and a horizontal member hingedly-coupled to the central member and extending perpendicular to a second side of the central vertical member. The upper edges of the central vertical member and the second vertical member of a first module provide support to a horizontal member of a second module, whereby various structures can be formed from a plurality of modules. Each module is stowable by rotating the second vertical member and the horizontal member about their hinged edges toward the central vertical member. One or more of the members can include key portions adapted to interlock with a member of an adjacent module when in an assembled configuration.
