The invention provides a commodity shelf, which is characterized in that a first frame, a second frame and a plurality of poles are movably connected to form a plurality of movable and deformable parallelograms, the adjacent parallelograms among the plurality of the parallelograms share the pole or the first frame or the second frame, so that the plurality of parallelograms can be linked in a interlink manner; the commodity shelf can deform between a stereoscopic article storage state and a flat plate article storage state; under the stereoscopic article storage state, a plurality of square holes for storing articles are formed by the first frame, the second frame and the plurality of poles; and under the flat plate article storage state, a single-layer flat plate serving as a shelf is formed by folding the first frame, the second frame and the plurality of poles.
