A roller box assembly includes a roller box and a bedding product contained in the roller box. The roller box includes a cardboard box portion, a pair of fixed-axis wheels, and a handle. The fixed-axis wheels are disposed along a corner edge of a bottom portion of the box portion. The handle portion is attached to the top portion of the box portion. In one embodiment, the bedding product is a mattress that has been compressed and rolled into a cylinder shape. A retail customer can purchase the bedding product at a retail store, and can then transport the purchased product out of the store by pulling the box from the handle such that the box rolls on its rollers.
