The coolest mattress you've ever slept in your life is from 100% natural Talalay Latex. Multiple layers of different densities maximize the physical characteristics of the Talalay Latex and provide extremely comfortable sleep. The Celsion Talalay Latex on the upper surface of the mattress minimizes pressure, providing ideal support for the most sensitive parts of boby such as waist and neck. With the thermoregulatory properties of Celsion Talalay Latex, body temperature is kept constant throughout sleep.
