Polyfill Pillow Inserts and Pillow Forms

Pillow Decor offers a wide range of stock polyfill insert sizes and can also provide custom sizes upon request. Also referred to as pillow forms, all our polyfill inserts are made from 100% new material and are hypoallergenic.

If you are buying one of our pillow covers, we have already preselected what we believe to be the best fitting insert options for each cover. If you are buying for a pillow cover that you own, we generally recommend buying a pillow insert one size larger than your pillow cover (for example, an 18" x 18" insert for a 17" x 17" cover). To measure a pillow cover, lay the empty pillow cover on a flat surface and pull the side seam taut against a tape measure. For more information on sizing, read: Making Sense of Pillow Sizes.

Please email or call us if you have any questions about which size of pillow insert will work best for your pillow cover.
