ABSTRACT:
A low profile roller includes a wheel mounted on a hollow hub and having a roller ball mounted within the hollow hub. The roller is configured to function in a first, low profile operating mode when the roller ball is in contact with a support surface and in a second, high profile mode when the wheel is in contact with the support surface. A base for a movable support platform includes a base frame and a pivot sleeve rotatably mounted to the base frame and non-rotatably mounted to an arm connected to the hub. The pivot sleeve is configured to rotate the low profile roller from between the first mode and the second mode. A butterfly foot pedal is operably connected to the pivot sleeve.
