A stand for supporting an object. The stand includes a base, a support member coupled to the base, and a movement mechanism adapted to allow the object to move along a range of travel relative to the base. The base includes a planar surface for resting on a support surface. The planar surface includes a first portion and a second portion. The first portion includes a pad for providing frictional resistance between the base and the support surface on which the base is placed. The second portion includes at least first and second wheels, for rotating the base about the pad such that the object is rotated about the pad when the base is rotated about the pad.
