A support arm is adjustable in length and is affixed to the center of a bottom cross arm to form a T-shaped structure. A pair of clamping devices are affixed to the opposite ends of the bottom cross arm and to the opposite ends of a top cross arm of the same length. The clamping devices in closed position support the cross arms in next-adjacent relation to clamp a rug between them with the rug resting on the support arm. In open position, the clamping devices support the cross arms in spaced parallel relation to position the rug therebetween. A plurality of mounting members are affixed to the bottom cross arm and the support arm.
