Display pedestals comprise at least one generally planar horizontal support member which is hollow, and at least one vertical column. The top surface and/or the bottom surface of the support member has least one depression or at least one projection, and at least one vertical column fits to the depression or projection. The interior volume of the hollow support member is filled with air or with a foamed polymeric or metallic material.
