A shelving system may comprise a pair of support brackets and a shelf platform supportable by the brackets. The platform includes a supporting portion, a rear flange on the supporting portion, and a front flange on the supporting portion. The shelf platform may be configured to be supported by the support brackets when a portion of the brackets extend upwardly from the platform and when a portion of the brackets extend downwardly from the platform. Optionally, a work platform is pivotable between usage and storage positions, and the brackets are pivotable between a deployed position supporting the platform in the usage position and a storage position allowing the platform to move to the storage position. Optionally, a mounting rail and at least one hook removably mountable on the rail may be provided. The hook may have a stabilizer tab that stabilizes the hook with respect to the rail.
