Two of our best pillows, back to back.
The buckwheat side locks into a cool, firm cradle that keeps your neck aligned all night. The wool side wicks moisture and sleeps soft, quiet and easy on allergies. Flip whenever you like, and tune each side with its own zipper.
The list most pillow makers hope you never read. None of it is in a Circadian pillow.
One pillow that answers two different nights.
Buckwheat hulls on one face for the nights your neck needs holding. Organic wool on the other for the nights you want it soft and quiet. A sewn cotton divider keeps them apart, so you flip rather than compromise.
- Fill
- Buckwheat hulls on one face, organic wool on the other
- Cover
- Organic cotton, with a cotton divider sewn between the chambers
- Weight
- About 10 lb, the heaviest pillow we make
- Adjust
- A zipper per side, and neither one affects the other
- Made
- Nobody made this one until you ordered it. Filled, weighed, balanced and closed by hand in New Jersey
- Refills
- Both fills sold separately, so it starts over instead of ending
Thousands of hulls that move, then lock.
The hulls shift as you settle and then interlock, so your head stops sinking and your neck stays where you put it. We polish every hull smooth, which is why the fill moves with a soft rustle instead of a crunch, and cuts the sound by up to 68 percent. Air moves freely between them, so this is the cooler of the two faces.
Wool that keeps the air at your face dry.
Wool wicks up to a third of its own weight in moisture while staying dry to the touch, so you wake up dry instead of clammy. The long fibers give it a springy, cushioned feel that holds its height, and the dryness the wool holds keeps dust mites out of the pillow without anything being added to it.

What the certificate covers
Organic wool on one side and an organic cotton cover. Buckwheat hulls are an agricultural byproduct, so no organic standard covers them. How it was made
Hulls air-jet polished and UV-sterilised. Wool scoured with biodegradable detergent, lanolin retained, left undyed. What we do not claim
We do not claim GOTS on this pillow and we do not call it an organic pillow. The wool side and the cover are certified; the hulls are not, and a pillow is only as certified as its least certified part. | |||||

Green Child Magazine
“Circadian’s buckwheat hulls are pre-polished, and were tested to be up to 68% quieter than standard buckwheat hulls.”
Amity Hook-Sopko, Green Child Magazine
Those are the hulls in the firm chamber of the pillow you own. Her piece covers the hybrid separately, and this is the line she stopped to verify.
Read the pieceThe ones people filmed themselves.
Not our shoot. Tap any one to go to the post it came from.
Two materials, two continents, one bench.
The hulls and the wool arrive at the same New Jersey workbench from opposite ends of the world, and neither one was grown to be a pillow.
A buckwheat farm in the United States
The hull is the shell around the grain, and it is inedible, so it has to come off before anyone can eat the groat. Every hull in your pillow is something the food system was always going to discard.
A certified organic farm in New Zealand
The wool side is the same wool that goes into our standalone wool pillow. It is scoured with biodegradable detergent, left undyed in its natural color, and the lanolin is still on every fiber.
A bench in New Jersey
The hybrid takes longer to build than anything else we make. Each one is filled, weighed, balanced and closed by hand, because the divider has to sit right or neither chamber works.
One zipper, and what you do to one side does not touch the other.
The divider is sewn in, so hulls stay on the hull side and wool stays on the wool side. Take one down and the other stays exactly where you left it.
Pick your side.
Buckwheat for firm support that holds your neck in line. Wool for a softer, quieter feel.
Mound the hulls.
Push them into a low mound in the middle and rest your head into it. They mold around your neck and hold that shape all night.
Tune each chamber.
Pour out hulls to soften the firm side. Lift out a layer of wool to lower the soft side. It arrives full on both faces.
Give it three nights.
The first night on hulls feels unfamiliar to almost everyone, and almost everyone stops noticing by the third.
Keep what you took out.
Store it dry. If you go too far, put back exactly what you removed.
How much you keep depends on how you sleep.
Both chambers arrive full. The right amount is whatever keeps your ear, shoulder and hip in one line.
Spine alignment · Buckwool Hybrid
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.
Buckwool works for every sleep position because each side does a different job. The buckwheat side gives firm cervical support for back and side sleepers. The wool side is softer, and you set its height for stomach sleeping. Each chamber adjusts independently through the side zipper.
A high pillow tips your head back and overextends your neck. Most stomach sleepers want a very low pillow, or none.
Press the buckwool hybrid flat so your head and shoulders sit close to level with the mattress.
Supports the natural curve of your neck so your chin sits level and the small space behind your neck is filled in.
Mold the buckwool hybrid until your head sits level with your shoulders.
Fills the gap between shoulder and ear so your spine runs in a single horizontal line from skull to hip.
Mold the buckwool hybrid until your ear, shoulder, and hip stack along one straight line.
Keep most of both fills
You have the widest gap to fill between ear and shoulder. Start on buckwheat with the hulls mounded high, and only pour out once your head is clearly propped rather than supported.
Pour out a cup or two
You need the curve of your neck supported without your chin being pushed toward your chest. Take hulls out a cup at a time and stop when your chin sits level.
Empty most of the hull side
Stomach sleeping wants almost nothing under your head. Pour most of the hulls out, or sleep on the wool side and lift a layer out of it.
Spot clean, never soak.
Empty the hulls first
Pour them into a dry container before the cover goes near water. Wet hulls do not recover.
Never machine wash the wool
Sponge spots with cool water and let it air dry.
Air it in the sun
A few hours of sunlight every few weeks refreshes the wool and the lanolin oil.
Both fills last for years. Refill the hulls or add a layer of wool through the zippers as they settle, and the pillow starts over instead of going in the bin.
The ones we hear most.
Start on the side that matches the problem you bought it for. Neck pain or sinking, start on buckwheat. Waking up warm or clammy, start on wool. Then flip whenever the night calls for it.
There is a soft rustle when you move, closer to dry leaves than to gravel. We polish every hull smooth first, which cuts that sound by up to 68 percent against unpolished hulls. Most people stop hearing it within a week.
Yes. Empty the hulls into a dry container first, wash the cover cold, air dry it, then refill. Never machine wash the wool.
Buckwheat hulls are dense, and there is a full wool chamber on the other side. It is the heaviest pillow we make, which is also why it stays exactly where you put it.
What goes well with this one.
The organic wool duvet
Wool moves moisture instead of trapping it, which is why one duvet works in January and again in July. GOTS Certified Organic on the fill and the shell both.
See the wool duvetThe organic cotton pillow
Cotton settles into a lower, denser shape than wool, which suits stomach sleepers and anyone who has been sleeping without a pillow. GOTS Certified Organic on the fill and the cover both.
