This pillow is made from soft silky kapok covered in organic cotton sateen. Kapok is a silky fiber, and feels much like milkweed or down. It is harvested from the seed pods of a kapok tree (the tree is never cut down). This natural pillow will compress with use but can be placed dry in a hot dryer for 10 minutes to help plump the pillow. This is our softest feeling pillow. Comes with a zipper so you can add or remove filling.
