A movable shelving unit for moving over ground surfaces in two different modes of operation consisting of a shelving unit and a movable base. The movable base includes a first set of wheels and a second set of wheels, each set of wheels having a first position wherein none of the wheels comprising the wheelset contacts a ground surface and a second position wherein each of the wheels comprising the respective wheelset contacts the ground surface. The movable base also contains a mode selector for moving the various wheelsets between the first and second positions. A brake mechanism is included to reduce movement of a wheelset. The shelving unit can be collapsible to allow for easier transportation and storage. The first wheelset is for moving the shelving unit over rough ground surfaces and the second wheelset is for smooth ground surfaces.
