An adjustable pillar includes a foundation structure and a hollow pillar housing. The foundation structure includes vertical rods. The upper ends of the rods are threaded. The lower end of the housing is open. The open base end forms an opening into the lower end of the cavity. The open base end and the lower end of the cavity are sized to receive therein the upper ends of the rods. A base is sized to fit substantially snugly telescopically into the open lower end of the housing. A weight bearing member is mounted inside the lower end of the hollow housing. Apertures in the member mate with the upper ends of the rods.
