The Airflow Series™ of mattresses employ three primary components to create quality mattresses which are unrivaled for breathability. It all starts with our state of the art, heat-dissipating air flow fabrics which are used on all exterior surfaces of the mattress for maximum breathability. Then, the sleeping surface is enveloped in our proprietary ZephyerGel™ for maximum air flow. Finally, the interior of each mattress includes AirFlow materials which allow for the exchange of fresh, cool air throughout the interior of the mattress. The result is an Airflow Series™ mattress which will keep you cool, dry, and extremely comfortable throughout the night.
