A retractable bunk or bed is disclosed. The retractable bunk can be used in a sleeper compartment so as to optimize space within the cab. The innovation can include a shaft around which a suitably strong, yet flexible, material bunk can be wound. Thus, in a closed or “hidden” state, the material can be rolled up around the shaft and stowed, for example behind a door or within a compartment as desired. In an open position, the material is extended in a horizontal manner and affixed to retain the “bunk” position.
