The Hearth & Harbor Cool Bamboo Rayon Pillow is filled with shredded memory foam that contours to your body, which features better airflow and adjustable loft. A zipper on the inner shell allows you to add or remove foam clusters for individualized comfort. Our pillows provide you with the relief, support and comfort you need for a good night’s sleep, by keeping your head, neck, shoulders and upper body aligned and supported in every sleep position. Woven from bamboo-derived rayon, the breathable, velvety soft pillow cover is removable and machine washable, allowing you to clean spills and stains as well as remove dust and pet hair.
