A child support device (200) includes a seat (204) and a panel (208) included in or adjacent to the seat. The panel includes a first panel portion (212) including a panel edge (216) defining a panel opening. The first panel portion has a first heat transfer coefficient. A location of the panel opening corresponds to a heat transfer region in which an expected heat received from a child in the seat is greater than a heat reception threshold, A second panel portion is in the panel opening and attached to the panel edge. The second panel portion includes a layered mesh having a second heat transfer coefficient greater than the first heat transfer coefficient and greater than a threshold heat transfer coefficient at which a temperature of the second panel portion while receiving the expected heat is greater than a room temperature by less than a threshold difference, wherein the threshold difference is at most five degrees Fahrenheit.
