A rotational mechanism for extending a sofa sleeper from an upright sitting position to a fully reclining and fully extended sleep position, having: a first rotatable member configured to rotate about a first axis; a second rotatable member configured to rotate about a second axis; a link mechanism attached to both the first and second rotatable members, the link mechanism being moveable along a length of both of the first and second rotatable members; and a drive mechanism configured to position the moveable link at positions along the length of at least one of the rotatable members such that movement of the link mechanism causes both the first and second rotatable mechanisms to rotate.
