Comfort	Specifically designed mattress to keep even the warmest of sleepers cool. You don't have to be a hot sleeper to love iComfort. You just have to like your sleep environment to be refreshingly comfy. Three cooling upgrades available: Cooling Upgrade (CF2000): 11.5" Additional cooling and firmer support. Max Cooling Upgrade (CF3000): 12.5" Cooler and more breathable. Max Cooling & Pressure Relief Upgrade (CF4000): 13.5" Feels and sleeps cooler, with air support layer to take pressure off joints. Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body. Gel Active® Max Foam (used only in CF2000 model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep. UltraCold System (used in the CF3000 and CF4000 models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.	Our top layer, the ThermaPhase comfort layer, is the culmination of years of development. Our comfort layer combines two different phase-change materials that target temperatures on both ends of the optimal sleep zone. Upon reaching an ideal sleeping temperature, the phase change material undergoes a molecular transformation that works to maintain the temperature at the optimal level. This results in a mattress that will keep you cool when its warm, and will help keep you warm when its cold. There is not a more technologically advanced, or more comfortable mattress available, period. Our ThermaPhase comfort layer, is the culmination of years of development. We combined two different phase-change materials that react to temperature fluctuation. The result is a "Smart" mattress that will react to heat and actively cool the sleeping surface. OR if sleeping conditions become too cold, the Thermaphase molecules will redistribute absorbed heat to help keep you warm.
Support	Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever. Carbon Fiber Memory Foam provides exceptional strength for back and neck support. Air Support Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.	Each layer was engineered with varying levels of density and weight capacity to provide dynamic support. Our top 3 layers are a patent pending hybrid-foam package that we call Z3. The Z3 package utilizes various pressure ratings that only engage when necessary, providing the right amount of support and comfort for any size user, and optimal pressure point relief for back and joint pain.
