A retractable stand comprises a base and two ribbons. Each ribbon has a coiled portion and an uncoiled portion. The uncoiled portions of the ribbons have a curved cross-sectional shape and are positioned in opposing relation to each other. Preferably, the curved cross-sectional shape of each uncoiled portion defines a convex surface and a concave surface, and the convex surfaces are in facing relation to each other. In one embodiment, the retractable stand further comprises a foot brace secured to free ends of the ribbons. Preferably, the foot brace includes an arm movable relative to the ribbons. The present invention further provides a method of supporting a device above a surface using the above retractable stand. The method includes uncoiling the two ribbons, resting the brace on the surface, and supporting the device on the retractable stand. Preferably, the step of uncoiling includes moving the brace away from the base.
