1. A mattress assembly, comprising:
a plurality of gas-filled chambers each having a top surface, the top surfaces of the chambers collectively composing a top surface of the mattress assembly;
a plurality of composite sensors, each composite sensor of the plurality of composite sensors being associated with a corresponding one of the plurality of the chambers, each composite sensor comprising:
a pressure sensor arranged to measure a pressure at a wall of the corresponding chamber; and
a temperature sensor arranged to measure a temperature of the corresponding chamber;
a plurality of chamber regulators, each chamber regulator being in fluid communication with a corresponding one of the plurality of chambers, each chamber regulator being configured, during operation of the mattress assembly, to pump gas at a first temperature and gas at a second temperature to the corresponding chamber, the first temperature being greater than the second temperature, wherein each chamber regulator comprises a first compartment and a second compartment separated from the first compartment by a divider, the first compartment containing gas at the first temperature and the second compartment containing gas at the second temperature; and
a controller in communication with the composite sensors and the chamber regulators, the controller being programmed to:
receive, from at least one composite sensor of the plurality of composite sensors, state data comprising pressure and temperature information for the chamber corresponding to the at least one composite sensor;
determine, based upon the received state data, an information about a patient's position relative to the corresponding chamber; and
based on the patient's position, control the chamber regulator for the corresponding chamber to modify a pressure and/or a temperature of the corresponding chamber.
