Wild-Harvested Kapok Pillow Fill Refill

Wild-harvested kapok grows inside seed pods on Ceiba pentandra trees in Indonesian rainforests. Workers harvest the pods, separate fiber from seeds, clean it, and ship it. The fiber moves from the tree pod to your pillow without passing through a single chemical process because the raw material is soft, hypoallergenic, and suitable for pillow filling without modification.

When the loft eventually drops in a Circadian Wild-Harvested Kapok Pillow, this refill brings it back without replacing the pillow. This refill is the same wild-harvested kapok fiber used in every Circadian Wild-Harvested Kapok Pillow, sold by weight so you can restore the loft you started with. Open the pillow's side zipper, add kapok by hand until the height feels right, seal it back up. Kapok is the lightest natural fiber on earth, so a small amount adds noticeable loft.

Origin and processing

Wild-harvested in Indonesia from naturally fallen Ceiba pentandra pods. Naturally hypoallergenic, naturally dust-mite resistant, free of every common allergen and chemical sensitizer found in synthetic fills. Wild-harvested fiber sits outside the GOTS system because the trees aren't farmed, so we use "organic cotton cover" only when describing the pillow, not the kapok itself.

What you get

Sealed bag in 1.5 lb or 3 lb. Because kapok is the lightest natural fiber on earth, even the 1.5 lb bag expands to a meaningful top-up. The 3 lb is enough to fully refresh any pillow from Standard to King, with plenty extra to top up a Body pillow.

How to use it

Open the side zipper on your Circadian Kapok Pillow and add kapok by handful, fluffing as you go because the fiber compresses in the bag and lofts when released. Standard pillows typically need a top-up every 12 to 18 months because kapok settles faster than cotton or wool. Regular fluffing (a quick shake a few times per week) extends the time between refills.

Why kapok feels different

Each kapok fiber is a hollow microtube, 80 to 90 percent air by volume, with walls only 1 to 2 microns thick. That hollow structure is why kapok feels like down and why it's the lightest natural fiber on earth. The fiber's cell wall has a natural waxy coating that repels liquid water, which is why kapok resists mold and mildew without any treatment.
