A reversibly positionable shelving unit housed within a cabinet enclosure and consisting of a frame with opposed top, bottom, and intermediate supports, each with a laterally disposed support post engaging channel formed therein. An upright spine or support post is rigidly secured to and extends between the top and bottom supports, and is disposed adjacent one lateral edge surface of the supports medially between opposed front and rear edge plate surfaces, with the outer surfaces of the supports having track followers coupled thereto. Camming support means are coupled to each support, and adapted to releasably, frictionally and grippingly engage the edge of the spine to lock the shelves in cantilevered support with the spine. Matching upper and lower guide slots are formed in the enclosure for engaging the follower means, with a linear bearing secured to the lower panel and in engagement with the undersurface of the bottom-most support.
