Abstract

A twistable and stackable shelf includes storage members, an elastic member, a first supporting pipe, a second supporting pipe, a first connecting member, and a second connecting member. Each of the first and second connecting member includes an end portion defining an inserting hole and an inserting portion defining a bottom groove and fluidly connected to the inserting hole. Two ends of the elastic member are inserted into the inserting holes and extend to the bottom grooves; two hooking members are arranged in the bottom grooves. The first and second supporting pipes form a vertical arrangement through the first and second connecting members and support the plurality of the storage members in a vertical direction. Or, the first and second supporting pipes form a horizontal arrangement through the first and second connecting members, and the storage members are twisted and stacked in the vertical direction.
