Abstract: A combination backpack configured to be worn about the torso of a user, and a child seat for a vehicle, includes a first closable pocket portion having a front face, which is configured to retain a cushion therein. Two shoulder straps each attached to upper and lower ends of opposite sides of the front face of the first pocket portion are configured to be worn about the torso of the user when used as a backpack. The combination includes a second closable pocket portion adjacent the first pocket portion, a rigid seatback support configured to be retained in the second closable pocket portion, and a child harness assembly releasably attached to the seatback support. When the second pocket is in an open position and the front face of the first pocket is placed on a vehicle seat, the cushion functions as a seat bottom for the child seat and the seatback support functions as a back support for the child seat.
