60-Night Trial
Temperature regulation takes a few nights to notice because you’re looking for the absence of a problem (no clammy skin, no waking up overheated). Give it at least a week. If after 60 nights you’re still waking up hot, send it back. Full refund, no questions.
Free Shipping & Returns
Free shipping and free returns during your trial period. Most orders arrive in 4 to 7 days. Thermoregulation is something you experience over time, not something you can evaluate from a product photo. That’s why the trial exists.
GOTS Certified Organic
The entire pillow carries GOTS certification: the wool fill, the organic cotton cover, and the production process. The wool comes from sheep raised without synthetic pesticides. The cotton is grown and dyed without chemicals. Everything was independently audited under OTCO approval number OT-024293.
Adjustable Fill (Zipper Access)
Wool compresses more slowly than cotton, but over months it will settle. When that happens, open the zipper and add more wool to restore the loft. The adjustment is gentler than with denser fills because wool fibers are naturally springy and a small amount of added fill makes a noticeable difference.
Designed in DC · Handmade in New Jersey
Every Circadian pillow is designed in Washington, DC, where all product specs and material sourcing originate. Each wool pillow is filled and sewn by hand at our New Jersey workshop. Wool requires careful distribution inside the pillow because it's a lofty, springy material that can clump if handled carelessly. Our workshop team fills each one slowly and checks the balance before closing it.
Naturally Hypoallergenic
Wool fiber resists dust mites without any chemical treatment. The lanolin and structure of the wool create an environment that dust mites avoid. For people with dust mite allergies, this is passive, permanent protection that doesn’t wear off or wash out, because it’s a property of the material itself, not something applied to it.
Every hot sleeper has tried the cooling products. Cooling gel pillows, cooling pillow pads, cooling pillowcases with fancy-sounding fabrics. They work for about fifteen to twenty minutes. The gel absorbs your body heat, reaches your temperature, and then you're back where you started: lying on a warm surface with no way to cool it down.
Wool approaches the problem differently. Instead of trying to stay cool (which is a losing battle against 98.6 degrees of body heat), wool manages the moisture that makes you feel hot. The fiber pulls sweat and humidity away from your skin, absorbing up to 30% of its own weight in moisture while remaining dry on the surface. Your skin stays dry, your perception of temperature drops, and you stop waking up clammy and overheated. The pillow didn't get colder. The moisture that was making you uncomfortable just isn't pooling against your face anymore.
This is the pillow for night sweaters specifically. If you wake up with a damp pillow or a damp face, wool changes that experience within a week. The sweat still happens, but it wicks into the fiber instead of sitting on your skin. And because wool stays dry on the surface, the pillow also resists dust mites naturally. Moist environments attract dust mites. Wool keeps the surface dry, so the mites don't establish themselves.
Most wool products you've tried that felt scratchy weren't low-quality in any other sense. They just used short-staple fiber, where individual strands are short enough to poke out from the surface and irritate your skin. The fill in this pillow uses long-staple wool, where each fiber is long enough to lie flat instead of standing up. Your face rests against it the way a well-made wool sweater rests against your neck, without the prickling that makes people assume wool always feels rough. Longer fibers also resist pilling and hold their loft better over months of nightly use, because there's more structural integrity in each strand.
The one thing to know upfront: fresh organic wool has a faint lanolin scent. It's subtle, earthy, and fades within the first week. Some people notice it, some don't. By the second week, the smell is gone entirely.
Every layer is GOTS certified organic (the fill, the cover, the thread), verified under GOTS license GOTS-10229 by Oregon Tilth. The certification is public because we think you should be able to check.
Spine alignment · Organic Wool
Three sleepers, three pillow heights.
Your spine stays neutral when the pillow fills the gap between head and mattress. That gap is different for back, side, and stomach sleepers.
Best for
All sleepers
Wool works for every sleep position. Side sleepers keep the loft tall, back sleepers pull some fill, stomach sleepers pull more. The temperature regulation does the same work in any position, which is why hot sleepers and night sweaters end up on this one.
Stomach
A high pillow tips your head back and overextends your neck. Most stomach sleepers want very little loft, or none.
Remove most of the fill so your head and shoulders sit close to level with the mattress.
Back
Supports the natural curve of your neck so your chin sits level and the small space behind your neck is filled in.
Remove fill a handful at a time until your head sits level with your shoulders.
Side
Fills the gap between shoulder and ear so your spine runs in a single horizontal line from skull to hip.
Keep most of the fill until your ear, shoulder, and hip stack along one straight line.

★★★★★
Better than my $250 Avocado
Sold my Avocado pillow on Facebook Marketplace after a week on this one. The wool fill is more responsive and breathable. And it was $170 cheaper. Not even close.
★★★★★
Four seasons pillow
Cool in summer, warm in winter. I've never had a pillow that works year round before. Usually I swap between a cool pillow and a warm one. This one just stays comfortable regardless.
★★★★★
Temperature regulation is legit
Was skeptical about the temperature claims but wool actually does regulate heat. I used to flip to the cool side constantly. Don't need to anymore. It's not cold, it's just never hot.
★★★★★
Night sweats gone
I've had night sweats for years. Tried cooling gel pillows, bamboo covers, even a pillow with a fan in it (yeah). Wool just wicks the moisture away. I still sweat but the pillow doesn't feel wet. Game changer.
5
I'm a hot sleeper and my wife is freezing year round. We could never agree on bedding. Switched to the wool pillow and the night sweats just stopped. It's not cold to the touch, it just doesn't trap heat the way foam did.
Dust mite allergy without a special cover
Got tested for allergies and dust mites were off the chart. Read that wool is naturally hypoallergenic and tried this without any allergen cover. Morning sneezing gone within a week.
Faint scent for about a week
There's a mild sheepy smell when you open it. Not unpleasant, just present. Gone by night five. After that it just smells like a clean pillow.
Inside the pillow
Long-staple organic wool. Wavy, alive, breathable.
The wool inside this pillow is long-staple, GOTS Certified Organic wool. That phrase carries the entire design.
Each fiber is naturally wavy and 3 to 5 inches long, twice the length of standard short-staple wool.
Long-staple wool spins into yarns with fewer exposed fiber ends, so the pillow surface feels soft against your face instead of scratchy. The wavy structure creates air pockets throughout the fill, giving wool its loft and its insulating capacity. The lanolin coating on each fiber pulls moisture into the wool's core while keeping the surface dry, so wool absorbs up to 30 percent of its weight in moisture before it feels damp. That is the reason hot sleepers stop waking up clammy in the first week.

From the founder
Built because nothing on the market worked.
I'm Jacob, founder of Circadian. Every pillow I tried either flattened in three months or hid a list of chemicals you'd need a glossary to read, so we built one that doesn't do either.

What's not in the pillow.
Most wool pillows are short-staple wool blended with polyester for cost. The wool gets scoured with harsh detergents, dyed with chrome-based compounds, and moth-treated with synthetic insecticides. GOTS Certified Organic means none of those steps touched this pillow. The wool is long-staple, scoured with biodegradable detergent, left undyed in its natural cream-to-tan color, and never treated with synthetic chemicals. The lanolin coating that makes wool naturally hypoallergenic is still on every fiber.
Questions? We've got answers
What's the best pillow for night sweats?
An organic wool pillow is one of the most effective options for night sweats because wool fibers actively wick moisture away from your skin rather than just trying to stay cool. The Circadian organic wool pillow absorbs up to 30% of its weight in moisture while remaining dry to the touch, so your face and neck stay dry even when you're perspiring during sleep.
How does a wool pillow regulate temperature?
Wool regulates temperature through moisture management, not surface cooling. When you sweat or generate humidity, wool fibers pull that moisture away from your skin and absorb it into their core. The surface of the wool stays dry, which keeps your skin from feeling clammy. This process works continuously throughout the night, unlike cooling gels that equalize with your body temperature within 20 minutes.
Does an organic wool pillow smell?
A new organic wool pillow has a faint lanolin scent that some people describe as earthy or sheepy. The scent is subtle and fades completely within three to seven days of regular use. After the first week, the pillow is essentially odorless. This is noticeably milder than the chemical off-gassing smell from memory foam pillows.
Is the Circadian wool pillow good for dust mite allergies?
Yes. Wool is naturally resistant to dust mites because the fiber’s structure and natural lanolin content create an environment that dust mites avoid. This resistance is a permanent property of the material, not a chemical treatment that washes off over time. For people with dust mite allergies, a wool pillow provides ongoing protection without any special covers or treatments.
Is an organic wool pillow vegan?
No. Wool comes from sheep. If you’re looking for a vegan-friendly natural pillow with temperature benefits, the natural kapok pillow is plant-based and hypoallergenic, though it manages temperature through breathability rather than active moisture wicking.
How does a wool pillow compare to a cooling gel pillow?
Cooling gel pillows work by absorbing heat, which means they start cool and gradually warm to match your body temperature. Most gel pillows feel warm within 15 to 20 minutes. A wool pillow works by managing moisture instead of heat. It wicks sweat and humidity away from your skin so the surface stays dry, which is what makes you perceive coolness. Wool’s approach works all night rather than wearing off.
Can you wash an organic wool pillow?
The organic cotton cover can be removed through the zipper and washed in cool water with gentle detergent. The wool fill itself should not be washed with water, as this can felt and damage the fiber. Wool is partially self-cleaning because lanolin inhibits bacterial growth. Occasionally airing the fill in indirect sunlight is enough to keep it fresh.
How long does an organic wool pillow last?
With proper care, an organic wool pillow lasts several years. Wool fiber is naturally resilient and bounces back more readily than cotton. The adjustable zipper lets you add fill as the wool gradually compresses, extending the pillow’s usable life. Most wool pillow owners get three to five years before the fill needs significant replenishing.
Is the Circadian wool pillow good for people with allergies?
The pillow is a strong choice for people with dust mite and chemical sensitivities. The GOTS certified organic wool and organic cotton cover mean no synthetic pesticides, dyes, or chemical treatments are present. Wool’s natural dust mite resistance adds another layer of protection. If you have a specific wool or lanolin allergy (which is uncommon but real), this pillow would not be suitable.
What type of sleeper is a wool pillow best for?
Wool works well for all sleeping positions because the fill is adjustable. Hot sleepers and night sweaters benefit most from wool’s moisture-wicking properties. The pillow provides moderate support (firmer than kapok, softer than buckwheat), making it a good middle-ground option for people who want temperature regulation without sacrificing comfort.
How does an organic wool pillow compare to an organic cotton pillow?
Both are GOTS certified organic with adjustable zippers. Cotton is denser and provides firmer support, making it better for people who want a solid, stable pillow. Wool is springier and lighter with stronger temperature regulation and natural dust mite resistance. If your primary concern is heat or night sweats, wool is the better choice. If you want a familiar, firm feel with the strongest certification story, cotton is the better fit.
