Abstract: A car seat assembly includes a first base coupled to a vehicle seat. The first base is structured to have a pair of wheel wells. A seat is provided to support a child. A second base is provided. The seat is coupled to the second base. A pair of legs is coupled to the base. Each of the legs is structured to form a scissor such that each of the legs is positionable between an extended position and a retracted position. A plurality of wheels is each rotatably coupled to an associated one of the legs. Each of the wheels engages a respective one of the wheel wells such that the second base is removably coupled to the first base. Each of the wheels abuts a support surface such that the seat may be rolled along the support surface after the second base is removed from the first base.
