Abstract: A shelving system is provided which includes a polygonal shelf assembly, shelf supporting assemblies and post. The polygonal shelf assembly includes at least three bracket receiving sections. At least three shelf supporting assemblies are provided for supporting the polygonal shelf assembly. At least three posts are provided for releasably coupling to the at least three shelf supporting assemblies for supporting a polygonal shelf assembly. Each of the shelf supporting assemblies includes a collar and a support bracket. The support brackets have a shelf receiving section. When assembled, each of the collars are frictionally coupled to the at least three posts and each of the support brackets are frictionally engaged to the collars. The at least three bracket receiving sections of the polygonal shelf assemblies are then releasably coupled to the shelf receiving sections of the support brackets to form a shelving system that may be easily assembled and disassembled.
