Abstract: A shelf support including a rod portion and a seating portion extending therefrom is provided. The rod portion is adapted for fixing to a support wall. The seating portion includes a spiral-shaped outer surface which constitutes a plurality of support surfaces for supporting a bottom portion of a shelf, where, when the rod portion is fixed to the support wall and the bottom portion of the shelf is disposed above the seating portion, rotation of the shelf support causes a portion of the spiral-shaped outer surface to engage the bottom portion of the shelf.
