This memory firm support pillow is made from shredded rayon from bamboo that keeps you cool. It features a hypoallergenic rayon from bamboo removable cover zipped around the eco-friendly and naturally cool shredded rayon from bamboo fill. Not only comfortable, it's also antimicrobial, bed bug- and dust mite- resistant, providing an allergen barrier. Best of all, we love that this pillow is machine washable and can be tightly rolled for easy care, cleaning, and storage.
