Abstract
A roller-supported base and guide track arrangement for use with stacked storage bins. The stacked bins are removably supported on the wheeled base which has front wheels which are adapted to directly rollingly engage the floor, typically a carpeted floor. The wheeled base also has rear wheels which are rollingly supported and guided on freestanding guide tracks which are positioned directly on the carpeted floor adjacent opposite sides of the base for controlling movement of the base solely due to engagement with the rear wheels thereof. The guide tracks comprise horizontally elongate upright loops which maintain a guided rolling engagement with the rear wheels.
