The Coop Home Goods pillow is stuffed with shredded Visco elastic memory foam and microfiber that can be adjusted to your preference for the perfect amount of neck support. The cover is made from machine washable Lulltra fabric in polyester-rayon, which provides breathability and superior softness. The entire pillow is dust-mite resistant and hypoallergenic, making it an excellent choice for those who suffer from allergies. One unique aspect of this pillow is its stretchy inner liner, which can be unzipped to adjust loft but also allows you to shape the pillow to support your unique sleeping position. With more than 17,000 reviews on Amazon with an average of 4.3 out of 5 stars, we highly recommend this option from Coop Home Goods.
