Using patented technology developed for NASA, these are the mattress pad and pillow protectors that help prevent nighttime chills or overheating. Embedded in the covers are millions of invisible microcapsules that absorb excess heat when one is hot and release the stored heat when one is cold, ensuring a comfortable temperature throughout the night. Ideal for couples with varying body temperatures, the microcapsules adjust independently, allowing it to respond to each sleeper’s individual micro-climate. With a 300-thread count 100% cotton cover, 100% polyester skirt, and 100% polyurethane backing. Includes one mattress pad and two pillow covers. Machine washable and dryable. Imported. White.
