    Abstract: A combination portable dolly and collapsible stool for transporting photography equipment and the like, and for providing an elevated platform for taking photographs. The legs of the stool are pivotally mounted at opposite ends of a rectangular box platform and are braced by members (which may be U-shaped) that are pivotally secured to vertical portions of the stool legs and which have free ends that are secured by a latching means in either extended leg bracing position or in collapsed carrying position.Rollers are mounted on the exterior of the legs adjacent the pivots so that when the legs are collapsed the rollers support the base platform as a dolly. In such collapsed condition, the legs rest within each other and are secured together by an interlocking means.
