Abstract

Abstract An upright furniture support for use in a freestanding article of furniture wherein one or more elements such as horizontal shelves or vertical display boards are mounted between a pair of such supports. Each support includes an upright hollow metal tube of square cross section and a base comprising a solid metal post of square cross section press fitted within the lower end of the tube and having beveled vertical edges, and a pair of rigid elongated members fixedly secured to and projecting in opposite directions horizontally from the lower end portion of the post for engaging the floor. The two elongated members may be downwardly opening channel members which are welded to the lower end of the post and have sidewall portions extending toward each other over the side surfaces of the post.
