If you find memory foam too warm to sleep on, try this new ?cool blue? air flow mattress topper. It combines all the benefits of temperature-sensitive memory foam with two clever innovations. First, it?s made from a new cooling gel memory foam that constantly adapts to the shape of your body in each new sleeping position, but won?t make you overheat like ordinary memory foam tends to do. Second, it has 5 sculpted zones that provide specific levels of support to various areas of your body. The rises and dips help to increase airflow and dissipate heat while minimising disturbance to your partner when you move around in the night.
