Three layers of supportive and cooling foam with a uniquely huggable feel. Designed and tested by our in-house ergonomist, our foam pillow is proven to align your head and neck for proper support. The supportive inner layer contours to your head and neck in all sleep positions, while plush outer layers offer cushion comfort. Purposefully designed to prevent you from overheating, tiny channels in the foam circulate air out and away. Plus, an extra breathable jersey knit cover helps you sleep cool throughout the night. Unlike other foam pillows, this one combines low- and high-density foams for a luxuriously squishy feel that keeps you blissfully comfy night after night (after night, after night…).
