There is an option of back seats for a C150 so I guess there probably also is for a C152.
Cessna even ran 1960 style ads showing how much space a 150 had with a Mom, Dad, and two All American children ready to pile in with their suitcases. Suspect it was shot with a wide angle lens and the door removed.
They didn't go as far as to say it would get off the ground though.
