Pillow stuffing is a material used to fill pillows and other soft furnishings. It can be made from a variety of materials, including DOWN, EIDER, KAPOK, and FEATHERS. DOWN is a soft, fluffy material found on the underside of birds such as ducks and geese. EIDER is a type of duck that produces a particularly soft DOWN. KAPOK is a silky fiber obtained from the seed pods of the KAPOK tree. Finally, FEATHERS are the light, stiff quills found on the wings and tail of birds. All of these materials can be used to make pillow stuffing for a comfortable and luxurious sleep experience.
