Abstract: The present invention is for a novel pivotable shelving system utilizing (in some embodiments) one or more D-shaped shelves that may pivot such that when it is in a cabinet and the flat portion of the D shape is at a front edge of the cabinet, when the shelf is rotated, a portion of the shelf extends beyond the front of the cabinet. Other improvements in some embodiments include devices having multiple swiveling spinners which may each operate/pivot independently as well as multiple shelves of varied geometry to enable taller items to be placed on the lower shelf and extent above an upper shelf.
