Abstract: An apparatus for facilitating adjustment of an adjustable foot comprises a base and an anti-friction element which allows the fully loaded foot to rotate with respect to the base. The apparatus may be attached to the foot, or it may be inserted under the foot but otherwise detached from it. In use, the base rests upon the floor and supports the anti-friction element and the foot; and the anti-friction element is positioned between the base and the foot. When a foot is placed upon the apparatus, the foot may be adjusted to affect the pitch of the table surface by applying torque to the foot. The foot rotates while the base remains stationary. A foot receiving plate, which is supported on the anti-friction element and in use rotates with the foot, can also be included in the apparatus. In one embodiment, the foot receiving plate includes support tiers, each of which is sized to accommodate a different size foot.
