A height adjustable pedestal comprises a base, a height adjustment column disposed above the base and supported thereon, and a table top or chair seat support disposed above the height adjustment column. The height adjustment column comprises at least two spring actuated telescoping height adjustment mechanisms. The height adjustment column typically additionally includes at least one stand tube each having a first and a second end. The first end includes an opening or hole through which a telescoping height adjustment mechanism passes. The second end of each stand tube is proximate to the base. At least one support, disposed vertically above or below the base of the pedestal, for securing the stand tubes together, may also be included. Telescoping height adjustment mechanisms used in the pedestal are typically gas springs. Supports for securing the stand tubes together may comprise a platform. Such platforms include attachment means to attach the platform to the base. Each of the stand tubes in this version extend vertically from the platform and is supported therefrom. Supports for securing the stand tubes together may also comprise at least one attachment bracket. Such attachment brackets are vertically separated from the base.
