US Patent 11103081 Climate controlled mattress system

A climate control system provides the desired climate conditions of temperature and humidity at a contact surface of a multi-layered structure. The climate control system includes a heating mechanism disposed between one or more foam layers of structure and configured to deliver heat to the contact surface and a separate cooling mechanism disposed in the foam layers. The cooling mechanism includes at least one fan assembly, air channels and reticulated foam layers configured to draw air away from the contact surface toward the bottom of the structure. An operational control system is used to control the heating mechanism and cooling mechanism to achieve the desired climate conditions on the contact surface in accordance with a desired time-based climate control algorithm.
