An adjustable leg assembly comprises an outer tube and an inner tube subassembly. The inner tube assembly comprises an inner tube, a floor support at one end of the inner tube, an expandable bushing at an opposite end of the inner tube, a rod extending through the inner tube and secured to the bushing and threadedly engaged with the floor support. The inner tube subassembly is inserted into the outer tube such that the bushing is confined within the outer tube and can be expanded into and retracted from contact with the outer tube by turning the floor support relative to the inner tube. In the preferred embodiment illustrated in the drawings, the floor support is a glide/tightener that provides a floor glide to support the leg assembly and that provides a tightener that is threadedly engaged with the bushing rod.
