Claim:
A caster-post-and-sleeve assembly use in a system supporting platform-like objects on posts, the caster-post-and-sleeve assembly comprising: a caster including a wheel and an elongated stem attached to the wheel, the stem being inserted into a central aperture of a post end of a post for attaching the caster to the post, and a post-supporting sleeve slidably coupling the post to the caster, the post-supporting sleeve including an inside diameter greater than an outside diameter of a post end, the post-supporting sleeve further including a first end, a second end, and an end piece coupled to the second end, the end piece having a central opening therein, the diameter of the central opening being not less than the diameter of the central aperture of the post end, such that, when the post is inserted into the first end of the post-supporting sleeve the post end of the post contacts the end piece, and such that when the elongated stem of the caster is inserted through the central opening in the end piece of the post-supporting sleeve and through a central aperture of the post end of the post so inserted into the post-supporting sleeve, the post-supporting sleeve supports the post end and inhibits deformation of the post end in a radially outward direction from the longitudinal axis of the post.
