Layer 1: ZenGEL™ - Cooling Comfort

The top 2.5” layer of foam is composed of ZenGELTM Phase Change Open Cell GEL Infused Viscoelastic Memory Foam (Shew, that’s a lot of technology!).

Enhanced Thermoregulation (3 cooling technologies combined)
ZenGELTM technology incorporates the thermoregulation of phase change material into open-cell viscoelastic gel-foam technology, providing improved temperature regulation.  Many mattresses on the market today do not feature any of these technologies- we have them all covered right here in the first layer of foam. Coincidence?  No, we have been working diligently over the last decade to combine these technologies into an extremely effective sleeping surface.

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 ZenGELTM 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.

Rapid Thermal Conduction (Quickly cools you)
ZenGEL™ 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.

High Heat Capacity (Can pull more of the heat from your body)
ZenGELTM
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, ZenGELTM 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, ZenGELTM material can increase the foam’s thermal capacity 10-35 times.

Variable Temperature Control (cools AND warms you when needed)
The distribution of phase change material throughout the foam and the fast conductivity of the open-cell visco and gel combination enable ZenGEL™ 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.
