Query: wagon seat

I have a basic metal radio flyer wagon. I bought this seat for my 14 month old son who loves to ride in the wagon. I feel much safer with him having something to lean on in the wagon. The only issue is that it doen not have a seatbelt. I have to use a belt and put it about my son and the seat back to keep him in the wagon.
