Did you know that 37.5 degrees Celsius is your body's perfect temperature? Our new and exclusive 37.5 Technology Bedding continuously adjusts to maintain a micro-climate of personal comfort for you. It dynamically maintains the relative humidity inside the bedding micro-climate surrounding you at 37.5% & also keeps your core body temperature around 37.5 Celsius (which is the human body's peak performance state) all night long - so you can sleep deeper and wake up rested and refreshed. It does this using activated carbon particles derived from volcanic mineral & natural coconut shell fibers. These particles are embedded in the bedding permanently and cannot be washed out. The system adapts to how you sleep and works non-stop to keep you cool if you feel too warm and warms you up if you feel too cold. The smooth and soft 300-thread count cover is made from a blend of 80% cotton and 20% 37.5 infused polyester and has a lofty, cool fill of luxurious down alternative fill of 60% micro-denier and 40% 37.5 infused polyester fibers. The BED GLOVE skirt is an all direction stretchable knit made up of 92% Polyester and 8% Spandex that fits snugly around your mattress and is good for mattresses up to 18" deep.
