A support structure for a display stand includes a pair of oppositely facing primary coupling units attached to opposite ends of a horizontal center support bar, and four vertical display stand legs which are attached to and extend downwardly from the coupling units. Each of the coupling units includes a horizontal base tube, a pair of lateral tubes which extend parallel to one another downwardly and perpendicularly away from the base tube, and a horizontal central tube positioned between the lateral tubes, which extends away from the base tube and which is perpendicular to both the base and lateral tubes. A nut is attached to the exterior of each coupling unit tube near any open end, and an L-bolt is threaded through the nut and an adjacent aperture through the tube to extend into the interior of the tube for fastening the tube to other bars, fittings, plugs or the like.
