How to care for it

Basic Care: Remove pillow from the cover before washing. Both items should be machine wash cold water on a gentle cycle with a mild detergent, and with like colors only. For best results use a front load washer. Only use non-chlorine bleach when needed. Tumble dry low heat until completely dry. Remove from dryer immediately and fluff after drying. Do not iron.

Pro Tip: You should wash your pillow 2-4 times a year. For best results use a front load washer. When drying, use wool dryer balls to reduce dry time and improve fluffing.
