Not all foam is created equal. And when your head hits this pillow, you'll understand exactly what this means. While all foam offers good support and durability, it can also trap heat, making a warm night tormentingly tropical. This all-new breathable foam features a unique cell structure that gives nearly double the airflow of ordinary memory foam—without sacrificing support or shapability. Breathe easy all night long and get a solid 8 hours of sleep with the Solid8 Aircell Breathable Foam Pillow.
