In accordance with principles described herein, portable heated seats, and methods and systems for using the same, are provided that overcome some (or all) of the problems commonly associated with existing seats. These portable heated seats are easily transportable, and are preferably provided with cushion material to compensate for various seating conditions that may otherwise be faced by a user. One or more heating elements, preferably made of flexible graphite felt, are also provided in each portable heated seat. The heat settings of the one or more heating elements are controlled by one or more on/off switches, open loop temperature regulators, pressure push switches, sensor switches, and/or fuse circuits. A backrest (similarly heated or not heated) may also be used in association with the portable heated seat. Various alternative embodiments are also disclosed.
