Abstract: A personal heating and cooling system comprising a chair, a pad comprising a length of flexible tubing and at least one heating element housed in an interior area of the pad, a pump configured to pump a volume of coolant (e.g., water) through the length of the flexible tubing, an intake trunk coupled to the pump and configured to deliver a volume of water from a reservoir (e.g., from a thermal insulated cooler) and a battery pack operably engaged with the pump and the at least one heating element. In certain embodiments, the pad may be integral to the chair and comprise seat and back portions of the chair. In certain embodiments, the pad may be removably coupled to the chair or other seating surface or may be laid flat.
