Abstract: A sprung caster wheel assembly includes a base member supporting an object thereon and a swivel member mounted for rotation about a vertical swivel axis below the base member. Two spaced apart pivot arms are pivotally coupled to the swivel member for pivotal movement about a first lateral axis and rotatably support a wheel between the free ends thereof. The wheel rotates about a second lateral axis parallel to the first lateral axis and offset to one side of the vertical swivel axis. A torsion spring is helically wound about the first lateral axis and is coupled between the pivot arm and the swivel member to provide a sprung suspension to the base member supported above the wheel.
