Your pillows are made with a combination of two kinds of superior memory foam fill! Unlike our competitors, this makes for a more restful and quality sleep! All of our pillow casings are made of 100% cotton Muslin fiber! They are machine washable and can be tumble dried. These are 'beefy' and 'overstuffed' pillows with high loft. Not like those 'flat ones' that other manufacturers sell. Take advantage of our superior product and our 90 day money back guarantee!
