Abstract: An apparatus for use with umbrella types of folding strollers includes a platform with two casters disposed under opposite rear corners thereof. A pair of members are attached to the platform and extend vertically a predetermined distance from two opposite front corners. The pair of members each include a ninety degree radius turn and continue to extend in a direction away from the rear of the platform. The pair of members each terminate in a loop, at least one of the loops having an axial offset wherein an end thereof is disposed further away from a center of the apparatus than is the remainder of the loop. A rod with an offset weight at a first end is provided. The main longitudinal axis of the rod includes a jog at an opposite second end. The rod can be inserted through the loop having the axial offset only if the offset weight is held vertically above the main longitudinal axis of the rod.
