Abstract: A file cabinet comprises a case mounted on four caster wheels for mobility. A stabilizing wheel is mounted on the underside of a lower drawer behind the front edge. When the drawer is open, the wheel engages the floor and supports the forward end portion of the lower drawer independently of the case. When the drawer is closed, the stabilizing wheel nests within a forwardly open slot in the bottom wall of the case and is automatically elevated out of engagement with the floor. In an alternate form, the stabilizing wheel provides floor support for the drawer in its closed position.
