Abstract: A basket with a bottom and peripheral walls defining a cargo space therein. At least three legs are mounted to the underside of the bottom and each leg has a wheel assembly at the distal end. The legs are hollow and the internal diameter increases from the distal end so that the other end, mounted to the underside, cooperatively coincides with openings on the bottom. The legs are removably insertable through the openings and housed within each other so that the baskets can be stacked up in a volumetrically efficient fashion. Removable covers are mounted on the openings, when the basket is in use, to prevent objects from falling inside.
