Abstract: An extendable bed mechanism connected to a sofa bed to allow conversion between a sofa and a bed in an easy, facilitated manner. The mechanism is relatively inexpensive and light weight and comprises a movable panel, two pairs of brackets and two sets of wheels or rollers for supporting the panel, preventing wobble and allowing minimum physical effort. A simple locking handle is also provided for restraining the panel in an extended or a retracted position. It is contemplated that Voraspring brand expanded polymer will be used for the cushions-mattress; in combination this assures a superior sleeping surface.
