Serta's iComfort has revolutionized Memory Foam Mattresses. No longer does the comfort of a Memory Foam Mattress, with its cushioning and support as well as pressure relief, have to bare the side affect of an over heated sleep. iComfort has created a Memory Foam Mattress that features layers of specialty Memory Foam that creates a cooler sleep surface, including Carbon Fiber Memory Foam and EverCool® Supreme Memory Foam. A new Max Cold™ Cover with the UltraCold System™, gives you a cool to the touch fabric, creating a mattress you can't wait to snuggle into. These Ultra Plush Mattresses are luxuriously comfortable and ideal for a side sleeper or a back sleeper who prefers a plusher feel.
