For those looking for airy, breathable comfort, this strategically perforated Air Pillow(Tm) is well-ventilated to help regulate sleep temperature. The carefully perforated viscose charcoal memory foam provides a fresh, breathable benefit that improves airflow between you and the pillow, keeping you 3 degrees cooler than other fabrics and optimizing the pillow s sleep temperature. Our viscose charcoal naturally eradicates unwanted odors by dehumidifying the air and wicking away moisture from the pillow fibers and fabrics.
