Abstract: A sofa has a first frame fixed to first and second side members and a mattress with a first section secured to the first frame and a second section located over the first section by a hinge to define a seat that is rotated about the hinge to define a first sleeping surface. A second frame is pivotally attached to the first and second side members with a second mattress attached thereto to define a back for the sofa. A rail is secured to the second frame and engages a beam that extends between the first and second side member to set an incline for the back. The rail is rotated to define a barrier when the second frame is positioned a horizontal plane to define a second sleeping surface. Legs that extend from the second frame engage the side members to retain the second mattress in the horizontal plane.
