The unique ThermaPhase GelTM technology incorporates the thermoregulation of phase change material into open-cell viscoelastic gel-foam technology, providing improved temperature regulation. Studies have demonstrated that the optimal skin temperature of a person that provides most comfortable and restful sleep is 87o to 90oF (30-32oC). This temperature is maintained through the infinitely reversible phase change of the ThermaPhase material, as it can absorb or liberate heat when it is in contact with a body having a surface temperature higher or lower than the target temperature.
ThermaPhase GelTM combines highly conductive, open-cell visco with the added heat capacity and conductivity of gel to produce a very powerful heat transfer system. Upon reaching an ideal sleeping temperature, the phase change material undergoes a molecular transformation. This change of phase results in an extremely high heat capacity that works to maintain the temperature at the optimal level.
ThermaPhase GelTM can act as a giant heat sink or source depending on temperature conditions, with its heat capacity peaking at the most comfortable temperature for sleeping. Compared with conventional visco foam, ThermaPhase GelTM material has up to 7-times greater dynamic thermal conductivity and over 650-times greater heat capacity in the target range. Depending on the amount loaded into foam, ThermaPhase material can increase the foam’s thermal capacity 10-35 times.
The distribution of phase change material throughout the foam and the fast conductivity of the open-cell visco and gel combination enable ThermaPhase GelTM material to meet the temperature needs of different regions of the body. Body heat can be absorbed from high-temperature areas like the torso and rapidly transferred to the cooler extremities. This results in a uniform distribution of heat throughout the mattress to maintain a comfortable temperature for restful sleep.
