Cooled (or air conditioned) seats work by confining cooled air directly in the seat where the passenger is seated.

Check your car seatâs instruction manual or look at the information label on the side of the car seat to find out its weight limit. Most convertible seats (those which can go both rear-facing and forward-facing) have rear-facing weight limits of 35 or 40 pounds, although some newer models go up to 45 or 50 pounds.
