The Slumberdown Cool Summer Duvet is designed for unpredictable summers. With its adaptive technology, this duvet takes heat away when you're too warm and gives it back when you cool down. Crafted to improve comfort through the night for more restful sleep, the temperature-sensitive fabric regulates your temperature by absorbing heat when you are too hot and gradually releasing it as you cool down, ensuring an optimal temperature. Its innovative coverless design eliminates bed-making worries. Made from hypoallergenic materials, it's safe for allergy sufferers. This duvet is washing machine and tumble dryer friendly, making maintenance easy. Simply wash on a gentle cycle at 40 degrees before a cool tumble dry. The cooling technology remains fully effective even after repeated laundering. For the ultimate cool sleep experience, combine with matching fitted sheets and pillowcases, and bid farewell to hot, uncomfortable nights.
