What kind of casters come on a mobile pedestal?

Most pedestals use twin-wheel polyurethane casters — smooth rolling on hard floors without scratching the surface. For carpet, harder nylon casters are easier to push around. Look for at least one or two locking casters so the unit stays put when you don't want it rolling. Larger casters (3 inches) handle uneven flooring better than smaller ones.
