A caster assembly (30) that can be used with furniture to support the furniture and to make the furniture mobile. The caster assembly has a housing (34) with a stem (32) that extends upwardly to be attached to the particular piece of furniture. Within the housing is a plurality of spherical rollers (36) that are supported within the housing so as to be rotatable about their center points (52) and therefore can rotate in any direction as the furniture is moved. In the preferred embodiment, there are three spherical rollers that are all equidistant from the center line or longitudinal axis of the stem so that the weight of the furniture that bears down upon the stem is supported equally by the spherical rollers contacting the floor. As a further feature, a glide cup (38) is provided that can be readily attached and detached from the bottom of the housing and, when attached, the glide cup covers the spherical rollers and presents a flat, planar surface that contacts the floor. |
