Abstract: A support device that attaches to a vertical pole so that objects can be supported along the length of a vertical pole. The support device includes a platform that has a midpoint and a peripheral edge. The platform defines a slot that extends from the peripheral edge to the midpoint, wherein the slot has a width at least as wide as the vertical pole onto which the platform attaches. A clamp element is selectively positionable within the slot. A bias mechanism is provided for biasing the clamp element into the slot toward the midpoint of the platform. A napkin holding mechanism is also provided. The napkin holding mechanism extends below the platform and holds napkins in a manner that enables single napkins to be readily removed as needed.
