Abstract
A portable, sectioned, rotatable platform member has four distinct portions, a central portion, a substantially flat table portion, a curved apron portion, and an edge wall portion. The platform member is supported by vertical rotatable bearing surfaces which are positioned under the substantially flat table portion of the platform member. Additionally, horizontal, rotatable, guide surfaces are located under the platform member to position the platform member and allow for its free rotatability.
