ABSTRACT:
Any number of generally identical shelves can be formed from any pair of generally identical semicircular shelf halves by removably attaching the shelf halves along the straight edge which subtends the semicircle. Each shelf half has an aperture in the straight edge concentric with the semicircle so that the shelf halves can be removably attached while encircling an umbrella table pole. A higher shelf is supported above a lower shelf by a triplet of generally identical struts removably attached to the top side of a lower shelf and removably attached to the bottom side of a higher shelf in tripod formation. A triplet of generally identical arm struts can be removably attached to the top side of the highest shelf in tripod formation so that accessories such as lights or flowers can be hung from the arm strut horizontal arm which projects away from the pole. The lowest shelf can be supported above the umbrella table surface by a space frame base, for example in the form of a right circular cylinder, or can be supported by the arm struts by attaching a triplet of arm struts to the bottom side of the lowest shelf in tripod formation so that the arms of the arm struts are positioned on and supported by the umbrella table surface.
