Kapok fiber (also known as Java cotton, ceiba, or Java kapok) is a natural stuffing for pillows, bedding, and upholstery that are made from the fibers of a kapok tree (Ceiba pentandra). Kapok is a large tree that can be found in tropical forests. To harvest the fiber, the pods of the tree are opened and the seed and fiber are removed. They are then stirred in a basket where the seeds fall to the bottom and are removed from the fiber. This fiber can be used as a natural plant-based alternative to down feather pillow stuffing. Kapok pillows are soft, plush, and compress easily. The fiber is so soft and airy that it is also referred to as silk cotton. It will not mold or mildew, just like all our fills. Its feel is similar to the light weight feeling of down, but without the allergies and the loss of loft that go with feathers. The silk is luxurious to the touch and washable. Kapok fiber is moisture-resistant due to its natural wax coating, quick-drying, resilient, buoyant, and airy. This makes kapok fiber excellent buoyant material for life preservers and insulation material for sound and heat. Kapok fiber is also hypoallergenic, meaning that it is an ideal solution for those that need an allergen-free bedroom. Its moisture-resistant characteristics make the fiber resistant to harmful microorganisms that can cause mold and mildew. Kapok fiber is an excellent pillow filling choice for those that need a natural alternative to conventional pillow filling materials such as polyester fiber, foam, and down feathers. With a zipper cover, it is easy to add more or remove fill to customize the pillow to your liking for that just-right feel. Kapok pillows can be fluffed and retain their shape well.
