A sliding dolly that is particularly adapted to loading and unloading awkward and heavy packages, mattresses, or box springs from a truck. There is a, a dolly back frame, and a dolly shelf. There is also a means for supporting the dolly over a floor or other surface. This support means may be a slider and or roller assembly. In the preferred embodiment, both the back frame and the roller assembly are joined to the shelf. The back frame is joined to and depends from the slider. The slider permits the attached back frame, shelf, and roller assembly to move along the slider. The slider is typically fastened along one of the sides of a truck near the comer where the top and sides meet. The roller assembly has one or more casters that reduce the friction of moving the sliding dolly along the side of the truck by holding the dolly back frame and shelf away from the side of the truck. A mattress, box spring or other heavy and large or awkward package is placed on the shelf, and then the truck driver or person unloading the truck would simply slide the sliding dolly to the rear of the truck where the mattress or other object being carried would be transferred to a fork lift or other mechanism for unloading or transferring the goods in the warehouse.
