Meet the most supportive, comfortable pillow available! Our memory foam is shredded so that, unlike traditional memory foam, it will not flatten, shift or clump. When you buy products containing certified foam, you can be confident that the foam inside meets certipur-us® standards for content, emissions, and durability, and has been analyzed by independent, accredited testing laboratories. This pillow is packed with additional features including rayon from bamboo and polyester blend cover and customizable fill. The 60% polyester/ 40% sustainable rayon from bamboo cover is woven with wicking channels that can further be treated with the coolest comfort advanced wicking system. Fabrics treated with the coolest comfort dry four times faster than 100% cotton, helping balance body temperature by wicking moisture away from your skin. The result is a cooler, dryer, more comfortable sleeping experience, regardless of the season. Our unique construction and extra filling (0.5lbs, included) allow you to easily add or remove filling to customize this pillow to your personal size, shape and preferred sleep position.
