US Patent 7845718 Bed formed from face to face chairs

The present invention is a device which quickly and inexpensively transforms two, face to face aircraft passenger seats into a horizontal bed surface adapted to provide a user with a flat surface upon which a user may lie on their back, side or stomach. A collapsible foundation block is adapted to form a space filling function as to a space between two face to face seats that are secured to a floor structure forming a horizontal surface. The foundation block is preferably inflatable and is supported from a floor surface between the two face to face seats, whereafter a supporting structure of the foundation block rises to a top surface generally parallel to the floor. The elevation of the top surface is approximately a level of a top surface of seat cushions of the two facing seats.
