The child seat includes a seat-back portion having at least one fastener pair on the lower surface thereof for securing the seat-back portion about a horizontal member of the back section of the seating area. Each fastener pair has first and second cooperating strips extending substantially lengthwise along the seat-back portion, and the first and second strips have lengths sufficient to adapt to the height of the back section. The child seat also includes a restraint attached to the seat-back portion and a belt adapted to cooperate with the restraint for restricting forward and lateral movement of a child placed in the seating area. The length of the seat-back portion is sufficient to adapt to the height of the back section of the seating area.
