A slide assembly for a drawer inside a refrigerator employs both side and central rollers which control both horizontal and vertical movement of the drawer through a first set of rollers employed at front and rear portions at each side of the drawer to control vertical movement within side tracks while the drawer is moved between an extended position and a retracted position. A second set of rollers is mounted along axes which are arranged 90 degrees relative to the first set of rollers and underneath the drawer. This second set of rollers control side-by-side movement of the drawer as it is opened and closed. In one embodiment, the second set of rollers is mounted in a refrigerated compartment and travel within a track or guideway mounted on the bottom of the drawer.
