For those looking for airy, breathable comfort, this strategically perforated Air Pillow™ 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.
