A device for supporting a person may include a thermoelectric generator configured to receive heat provided from the person. The device may further include a first heat conductor overlapping the first thermoelectric generator and configured to conduct the heat to the thermoelectric generator. The device may further include a second heat conductor overlapping the first heat conductor and configured to conduct the heat to the first heat conductor. The first heat conductor may be disposed between the first thermoelectric generator and the second heat conductor. The second heat conductor may be softer than the first heat conductor. The device may further include a heat sink thermally connected to the first thermoelectric generator.
