A collapsible dolly assembly includes a pair of frames that are each selectively urged between a deployed position and a collapsed position. A pair of rear wheels is rotatably coupled to the frame to roll along a support surface. A pair of front wheels is rotatably coupled to the frame to roll along the support surface. A dolly is hingedly coupled to the frame to support an object thereby facilitating the object to be transported along the support surface. A pair of skid units is movably coupled to an associated one of the frames. Each of the skid units is selectively positioned in a deployed position. In this way each of the skid units frictionally engages a staircase thereby facilitating the object to be urged upwardly and downwardly along the staircase. A braking unit is movably coupled to the frame to selectively engage the staircase when the skid unit is positioned in the deployed position. Thus, the braking unit retains the object at a selected point along the staircase.
