Self Locking Futon Frame Information
                   John Pendley

 • The futon’s linkage design locks the frame
   in only two positions. Any time the futon is
   in between the couch or bed position, it is
   free moving.
 • The serpentine slots increase the rigidity of
   the futon frame. A roller element connects
   these serpentine slots with the frame’s
   linkage.
