A slide-out room for recreational vehicles, sleeper cabs of trucks, and similar mobile living quarters is supported for movement through an aperture in the side wall of the mobile living quarters by a set of four linkages, two of which are mounted between each side of the slide-out room in the corresponding side of the aperture of the side wall of the unit. When the slide-out room is fully retracted within the mobile living quarters, one of the linkages on each side of the slide-out room is fully extended and the other is fully collapsed. As the slide-out room is moved toward the fully-extended position, the other linkage gradually expands and the one linkage collapses, so in the fully extended, as well as the fully retracted position, the slide-out room is supported and aligned for movement through the aperture in the vehicle slide-out room, and the slide-out room is continuously supported as it travels between the extended and retracted positions. Accordingly, the slide-out room is suspended above the floor of the main living quarters and does not slide on the floor of the main living quarters, so that actuation power requirements are minimized. The linkages are designed to maintain the floor of the slide-out room level during its movement between the extended and retracted positions.
