An article of luggage exhibits improved mobility characteristics by mounting two sets of wheels to its bottom surface and a slidable and pivotable handle to its top surface. A first set of wheels projects from the bottom surface to a height greater than the projection of a second set of wheels so that the article is highly maneuverable when the article is in its upright orientation supported by the first set of wheels. The second wheels project from the bottom surface at a location more closely proximate a transverse edge of the bottom surface than the first wheels so that when the article is tilted about the second wheels, it may be stably maneuvered by a user during fast-paced movement or cornering.
