Latex is a naturally breathable and self-ventilating material that does not cause overheating. It is constructed with millions of interconnected air bubbles that allow instant air circulation and keep the mattress topper fresh and cool all night. Latex is not a heat-sensitive product and does not react to body temperature. We recommend using natural cotton bed sheets and duvets to create a pleasant microclimate in your bed. The mattress topper will promote comfort, rejuvenation, and deep, restful sleep.
