The Bestier cooling shredded memory foam pillow combines adjustable comfort with a dual-sided removable cover. The cool-touch side is made of 34% Ice-Silk Fabric and 66% polyester, while the reverse side is made of 36% bamboo-derived rayon and 64% polyester for a different surface feel. Open the outer cover and inner liner zippers to access the shredded memory foam, then add or remove small amounts of fill to adjust the loft and support to your preference. [PACKAGE SENTENCE] The memory foam is CertiPUR-US certified. [INSERT OEKO-TEX WORDING AFTER CERTIFICATE SCOPE IS CONFIRMED.] For cleaning, remove and machine wash the outer cover only; do not machine wash the inner pillow or foam fill. The pillow is compressed for shipping. After opening, pat and fluff it, distribute the fill evenly, and allow enough time for full expansion before use. Recovery time may vary after extended compression. Because comfort preferences vary, adjust the fill in small steps and test the pillow before making further changes.
