The Purple Pillow is made from the same material in much the same way. It is a stretchy, durable, non-toxic, food-grade material that is arranged in a grid made of hundreds of little triangular cells. It allows your head to rest comfortably on top of the pillow while the cells give way and mold to your contours.What is pillow fabric?
Pillows consist of a filler material enclosed in a fabric cover or shell. Covers are made of cloth, such as silk, known as the pillow case or pillow slip. Some pillows have a fancier cover called a sham which is closed on all sides and usually has a slit in the back through which the pillow is placed.
