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