No. All of our mattresses are designed with coolling features build in to regulate body temperature so that you can fall asleep faster and stay asleep longer and we do not use foams that cause body temperature to rise .Sleep science dictates that sleeping at a cooler temperature allows for longer periods of REM sleep, which increases the production of natural growth hormone that our body makes to aid in muscle recovery. Lowering your body temperature by 3 degrees, provides the most optimum environment for you to fall asleep faster and stay asleep longer and the longer you are in REM sleep, the more restorative your sleep will be. Our mattresses are designed to sleep cool in order to provide the greatest health benefits to our customers. We use specialty foams like copper infused, wool for natural temperature regulation and moisture wicking and cooling celiant and tencel based covers. Our mattresses are recommended by doctors and chiropractors because of our dedication to designing products that maike sense based on the science of sleep.
