The mattress also features a removable and washable quilted Outlast® mattress cover. Outlast® is a technologically advanced material that was originally developed for NASA astronauts to control extreme temperature fluctuations during space flight. The Outlast® fabric is designed to draw heat away when your temperature rises, the heat energy is stored, and then released when you begin to cool down, keeping your body not too hot, not too cold, but just right during the night. This regulation of body temperature means you're less likely to wake during the night, which ensures the deepest sleep possible. The temperature sensitive memory foam layer provides comfort and support to your shoulders, back and hips, and works in harmony with your body to ensure that you are sleeping in the correct anatomical position, meaning you can wake feeling refreshed and free of any minor aches and pains. Memory foam also offers relief for your pressure points, which encourages healthy blood circulation, as well as reducing the need to toss and turn during the night, meaning a deeper and more restful sleep. The Double Outlast® Classic Memory Foam Mattress is hypoallergenic and antibacterial, and also inhibits the development of dust mites, meaning it's the perfect sleep environment for sufferers of allergies and asthma. Manufactured in the UK with quality raw materials and detailed finishing, you can purchase your mattress with the confidence of a 5 year manufacturer's warranty from one of the UK's leading memory foam mattress manufacturers.
