ABSTRACT:
A furniture dolly comprises a cross-shaped frame having swivel casters at three corners thereof in normal contact with the floor and a fourth upraised swivel caster for negotiating obstructions. The dolly includes an upper furniture receiving ledge including a shelf onto which one end of an item of furniture can be placed by one man, after which the furniture is suitably moved in a desired direction with the upraised fourth caster extending forwardly. Should an obstruction be encountered, the upraised caster passes thereover and then acts as a brace while the remainder of the dolly is urged thereover.
