Upgrade your sleep with the Boyd Sleep Gellux® Cooling Gel Foam Mattress Topper. This plush mattress topper is made from advanced comfort foam to provide cushioning and ergonomic support. Patented Gellux® technology combines the benefits of cooling gel with a responsive foam. Because Boyd Sleep toppers are liquid gel-infused, they wick away body heat to help you sleep cool all night. A special Multi-Zone sculpted foam design promotes airflow and gives you support where your body needs it most. In addition, Air Flow perforations in the foam increase air circulation to prevent body heat build-up through the night. Firm mattress keeping you awake?
