Fabric composition: 100% Microfiber which keeps it breathable, dry, and softer. Pillow interior design: The pillow interior is filled with 80% original shredded memory foam and 20% Climaloft polyester fiber. It has high-quality resilience and is not easy to deform. Open the pillow zipper and increase or decrease the number of broken sponges to adjust the height for a more comfortable sleep. Easy to clean: Open the zipper, remove the memory foam, ventilate it, and clean the fabric part to keep the liner clean and hygienic. Say goodbye to the entire pillow in the washing machine.
