A seating unit for accommodating an adult in a seated position and having a child restraint seat convertible from a position stored within the back of the adult seat to a position for holding and restraining a child. The child restraint seat has a generally U-shaped restraint bar member which extends horizontally from the seat back in the open position and which pivots about the ends of the legs to a vertical closed position, wherein the restraint bar lays flush with the forward surface of the seat back and the bight portion of the U shape forms the top edge of the seat back. The child seat also has a seat cushion portion which pivots about its lower edge to lay horizontally in the opened position upon the adult seat and which pivots vertically to lay flush in the seat back and nest between the legs of the restraint bar in the closed position.
