Have you ever bought a zippered pillow cover that you really liked and then bought a pillow insert the same size as the pillow cover? Did the pillow go flat after a few months of everyday use? The reason for this is the pillow insert is the same size as the pillow cover. We suggest when buying a pillow insert, buy one two inches longer in the length and width than the pillow cover. Your pillow will be plush and firm. All of our pillows at My Chic Farmhouse have a pillow insert of 22” while the pillow cover is 20.” The Totally Chic Pillow by Chez Moi is an example and can be found here when you click on the link. Happy decorating with pillows!
