The Smartfil Technology Pillow is every eco-friendly buyer's dream! The smartfil technology transforms collected recycled plastics into small pellets that are heated and spun into very fine, soft-thread, eco-friendly premium polyester fiber. The polyester fiber is then filled into a embossed, soft touch microfiber fabric shell that has a gusset style construction for long-term durability. The fibers offer anti-microbial protection and act as a shield preventing bacterial growth, leaving you with a clean and fresh sleeping environment. This product is easy to care for - simply machine wash and dry on delicate to achieve your preferred level of freshness.
