<p>A furniture member swivel base includes a hollow first ring having L-shaped walls, including an outer wall vertically oriented and a ball contact wall horizontally oriented in an operating position. A hollow second ring includes ball bearing cavities proximate a second ring outer perimeter. The second ring is positioned below the first ring in the operating position. A ball bearing is rotatably received in each of the ball bearing support cavities and extends partially above the second ring to rotatably support the ball contact wall and permit the first ring to rotate with respect to the second ring. The first ring is fixed to the furniture member so the furniture member is supported on the first ring. The furniture member and the first ring are rotatable about an axis oriented transverse to the second ring with the second ring non-rotatably in contact with a floor surface.</p> |
