Circadian Natural Kapok Pillow

The pillow that stays cool and never goes flat.
Kapok fiber is 80% air. That means this pillow breathes like nothing else and stays 6°F cooler than down all night. The naturally buoyant fibers spring back instantly, maintaining perfect loft for years.
No heat buildup. No flattening. No allergens.
Why Kapok Works
Naturally Cool: Hollow fibers circulate air continuously, dissipating heat 3x faster than down
Stays Supportive: Retains 94% of loft after 1,000 nights. Most synthetic pillows lose 40% in six months
Hypoallergenic: No lanolin, no dust mites, no chemical treatments needed
Lasts 7-10 Years: Kapok doesn't break down like down or memory foam
Specifications
- Fill: 2.3 lbs pure kapok fiber
- Shell: 300-thread-count organic cotton
- Care: Spot clean, air monthly

Questions? We've got answers
What is a kapok pillow?
Kapok is a silky plant fiber harvested from seed pods. It’s ultra-light and airy, creating a plush feel that’s more breathable than typical down-alternative fills.
- Best at: Plush comfort, breathability, lightweight loft
- Best for: Side sleepers who want softness, hot sleepers who still want “cloud” comfort
- Not ideal for: People who want very firm, immovable support
Who is a kapok pillow best for?
Sleepers who want a soft, cloud-like pillow. Especially back sleepers, and side sleepers who like a plusher feel.
How does kapok compare to cotton or wool?
Kapok feels loftier and lighter; cotton feels denser and more traditional, and wool feels more supportive and springy.
Does kapok sleep cool?
Kapok is naturally breathable and tends to feel cooler than foams, with a lighter, less “heat-trapping” sensation.
How do I adjust loft correctly?
Start by removing a small amount of fill, then build a shallow “nest” with a slight ridge under the neck. Small changes can make a big difference.
How much fill is in each pillow?
Each Circadian pillow ships overstuffed by design so you can dial in the perfect height and firmness. Use the zipper to remove a little fill until your neck feels aligned and your shoulders can relax. Then store the extra fill for seasonal adjustments or future top-offs.
Are the kapok pillow certified organic?
The cover uses certified organic cotton fabric for traceability; kapok is a natural fiber but isn’t typically GOTS-certified, and certification isn’t the only indicator of comfort or quality.
If third-party certification is a must-have, we can point you to our certified organic options (cotton/wool).
How do you clean the hulls? Do you use chemicals or roasting?
We use a proprietary cleaning method using air-jet propulsions to avoid chemical treatments and avoid roasting/heat processing. We use multi-step air-cleaning and dust-removal methods designed to reduce fine particles and improve “pillow-grade” feel. This typically eliminates 60% of the buckwheat pillow crunch.
Can I buy extra fill later?
Yes, if you want to refresh loft over time or use fill for other pillows/projects, we can help with bulk fill. Contact us here.
How do I choose the right pillow for me?
The fastest way is our pillow quiz (built to match sleep position + preferences to the right fill). If you’d rather talk to a human, email us and we’ll recommend a fit based on what you’re trying to solve.
When will I get my order?
We ship within 1-2 business days. Standard shipping takes 3-5 business days within the US. Contact us here if you'd like the tracking number and expected delivery date.
Are your pillows adjustable?
Yes, all of our fills can be adjusted by removing or adding fill through the zippered opening until the loft feels right for your neck and sleep position.
When will I get my order?
We ship within 1-2 business days. Standard shipping takes 3-5 business days within the US. Email us at jacob@circadianrest.com if you'd like the tracking number and expected delivery date.
What is your sleep trial / return policy?
We honor a 60-night trial. Because many pillows can’t be resold after use and shipping heavy natural fills can be wasteful, we often use a “second life” return approach (keep/gift or donate/rehome) while still taking care of you financially.
Will this help with neck/shoulder discomfort?
Many customers shop for better alignment and support. The key is matching sleep position + loft + feel preference; we’re happy to help you get the fit right.
Does it have an odor when it arrives?
Natural materials can have a mild “fresh material” scent at first. Airing it out (and using a breathable pillowcase) typically resolves this quickly.
Can I get material samples before buying?
Yes, we can mail small material samples so you can feel the difference first (we typically charge a small amount to cover shipping). Please email us at jacob@circadianrest.com to request material samples.
