The Cooltex Bed features a mattress originally started off as an experiment, which saw our foam supplier mixing memory with latex. The result of this experiment resulted in a foam with very special properties. The 2″ Laytech foam in this mattress has properties of both latex and memory. When sat/lying on it, it feels and behaves like memory, very supportive and comfortable, but at the same time DOES NOT absorb heat like a memory, instead it stays cool, more along with your body heat, just like latex. At the heart of the mattress is an orthopaedic spring to add more support and comfort.
