A seating unit for accommodating an adult in a seated position has 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 an 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. The child seat also has a seat cushion portion which pivots about its lower end to lay horizontally in the open position upon the adult seat and which pivots vertically to nest between the legs of the restraint bar and lay flush in the seat back in the closed position. A top cushion extends between the stored restraint bar and the top of a high back style seat. The top cushion is flipped over the top of the seat back for child use.
