A trolley having two castor wheel assemblies mounted to a trolley frame. The castor wheel assemblies are mounted toward a rear of the trolley frame whereas another pair of conventional castors are mounted to the front of the trolley frame. The castor wheel assemblies are not identical insofar as swiveling of the assemblies is limited in a direction inwardly of the trolley only. It has been found that limited swiveling of one of the castor wheel assemblies only such as at an offset angle provides more efficient guided steering of the trolley.
