Buckwheat Pillow
Takes the exact shape of your neck and locks there, so your head never sinks out of line through the night.
Best for firm, mouldable cervical hold
Natural pillows for neck pain
Most pillows feel supportive the moment you lie down, then pack down under the weight of your head, so an hour in your neck is bent away from your spine and the strain sets in. These fills keep their shape and lock to the curve of your neck.

Buckwheat, for most people. The hulls flex under your head, interlock into the shape of your neck, and hold it there, which is the firm and steady hold that keeps your head level with your spine. If a hard surface against your cheek is what put you off firm pillows, the Buckwool Hybrid gives you the same hold with organic wool on the reverse. What matters more than the fill is the height: set it so your head sits level with your shoulders, and leave it there.
Each card says how the pillow holds your neck and who it suits. Every one opens at a full-length zipper, so you can set your head level with your spine and leave it there.

Takes the exact shape of your neck and locks there, so your head never sinks out of line through the night.
Best for firm, mouldable cervical hold

A firm buckwheat side for the bad nights and a softer wool side for the easy ones, each set on its own.
Best for neck pain that changes night to night

Springs back as you move instead of flattening, so it holds your head up with a softer feel than buckwheat.
Best for people who want holding without hardness

Our most tightly packed fiber, so it stays put under your head for years instead of packing down in months.
Best for a steady pillow with nothing to break in

Springy enough to cradle your neck without pinning it, for sleepers who want holding without a hard surface.
Best for lighter hold, and warm sleepers

Low and soft, for stomach and combination sleepers whose necks bend back on anything tall.
Best for sleepers who need the least height
Why your neck aches by morning
A pillow can feel perfect the second you lie down and still leave you sore. What matters is what it does at hour three, once your head has pressed the fiber flat.
1
You lie down, your neck is level, and nothing about the pillow warns you what the next six hours will do.
2
Foam and down pack down under the weight of your head and let it settle lower than it started.
3
Your head drops below the line of your spine, and the muscles hold that angle rather than resting.
4
It is eight hours of a slightly wrong angle. Nothing hurts at three in the morning, and everything hurts at seven.
Give your head a base that holds instead of sinking and your neck keeps the neutral line it wants all night. The muscles rest, and the morning stiffness people come to expect tends to ease over the first week or two.
Firmest hold
Buckwheat is the fill physical therapists point to, and the reason is simple. The hulls flex under your head, then interlock into the exact shape of your neck and hold there, so your head does not slowly sink the way it does into foam. You set the height once and it stays put until morning.
At about eight pounds the pillow stays planted on the bed, part of why the hold feels so steady, and the hulls run 3 to 5 years before they want topping up. They pack in loosely, so air moves through them, which is how you get a firm pillow that does not trap heat. We polish them smooth before they go in, which cuts the rustle by up to 68 percent.
Two firmnesses
Some nights your neck wants a firm hold that pins it in place, and some nights it wants a soft place to land. The Buckwool Hybrid gives you both in one pillow. A firm buckwheat side that locks your neck, and an organic wool side that cushions it, kept apart by an inner cotton wall so each side sets on its own.
You turn it over based on how your neck feels that night, instead of owning two pillows and swapping them in and out of the same case.
Hold with give
Latex gives you a hold that moves with you. Our slow-pour Dunlop is dense and springy, tapped from rubber trees in Sri Lanka and poured slowly so the density evens out top to bottom, and it keeps holding for up to a decade without matting.
It carries your head at the height you set and pushes back as you turn, rather than flattening into a dent the way foam does. You get the held-up feeling of a firm pillow with a more forgiving surface than buckwheat, and the latex itself is tested to OEKO-TEX Standard 100 Class 1, the strictest grade there is.
They all keep their shape better than foam. What differs is how hard the surface feels and how fast it answers when you move.
| Fill | How it holds your neck | Who it suits |
|---|---|---|
| Buckwheat | Hulls flex, then interlock and lock the shape | The firmest, steadiest hold, and side sleepers with broad shoulders |
| Buckwool Hybrid | Buckwheat hold one side, cushioned wool the other | Necks that ache some mornings and not others |
| Tree-Tapped Latex | Pushes back and returns as you move | People leaving memory foam who still want give |
| Organic Cotton | Dense enough that it settles evenly over years | Back sleepers who want steady and silent |
| Organic Wool | Springy cushioning that carries without pinning | Lighter hold, and anyone who sleeps warm |
| Wild-Harvested Kapok | Low and soft, the least height of any fill here | Stomach sleepers whose necks bend back on anything tall |
| Memory foam | Softens under body heat and lets you settle lower | The pillow most people on this page are replacing |
Buckwheat. The firmest, steadiest hold we make, and it will not let your head drop out of line while you sleep.
Buckwheat Pillow ›The Buckwool Hybrid keeps the buckwheat hold on one side and gives you organic wool on the other. Flip it to suit the night.
Buckwool Hybrid Pillow ›Latex. You keep the held-up feeling that made you buy foam and lose the sinking that made you give up on it.
Tree-Tapped Latex Pillow ›Kapok, taken low. Stomach and combination sleepers usually need far less height than they have been sleeping on.
Wild-Harvested Kapok Pillow ›Buckwheat, for most people. The hulls flex and lock to the shape of your neck and hold it there all night, which is the firm, steady hold physical therapists tend to recommend. If a firm pillow is more than you want, the Buckwool Hybrid gives you that hold with organic wool on the other side, and the Tree-Tapped Latex holds your head up with more give.
Usually, as long as the firmness holds. The trouble with most pillows is that they feel firm the first minute, then pack down and let your head sink out of line. A fill that keeps its height, like buckwheat or dense latex, keeps your neck neutral, and that is what eases the strain.
Enough to keep your head level with your spine, and no more. Side sleepers need a taller pillow to fill the gap out to the shoulder, back sleepers need less. Every Circadian pillow unzips so you can add or remove material until your head sits level, then leave it there.
A pillow cannot fix an injury, but the wrong one holds your neck at a bad angle for eight hours a night and makes everything worse. The right height with a firm, steady hold lets the muscles rest, which is often enough to end the morning stiffness people assume they are stuck with. If the pain is severe, new, or radiating down an arm, see a clinician rather than buying a pillow.
Give it a week or two. The first couple of nights on a firm hold can feel different while your neck gets used to staying in line. Most people notice the morning stiffness easing within two weeks, which is part of why the trial runs sixty nights rather than thirty.
No. Your shoulders belong on the mattress and the pillow fills the space from the top of your shoulder to your head. Pillow under the shoulder tips your head forward and undoes the thing you are trying to fix.
A contour pillow decides your neck's shape for you, at one fixed height, and it is right only if your body happens to match the mould. An adjustable pillow lets you find the height your neck wants and change it when you change. That is the argument for ours, and it is why every one has a zipper.
It usually points at height rather than fill. One-sided pain often means the pillow is right for your back and wrong for your side, or the other way round. Set the height for whichever position you spend the most of the night in, and consider the Buckwool Hybrid so you have a second option on the reverse.
It can feel strange for two or three nights, particularly moving from something soft to a firm hold, because your neck has been holding a bent position for a long time and level feels unfamiliar. If it is still worse after a week, take height out rather than giving up on the pillow.
Buckwheat if you want the firmest, most locked-in hold and do not mind a hard surface. Latex if you move a lot in the night and want the pillow to answer as you turn. Both keep their height where foam does not, which is the property that matters most here.
Set the height on the first night, sleep on it for a few weeks, and see what the mornings tell you. Every email reaches a real person in our New Jersey workshop, and most get an answer the same day.

“I have owned more pillows than I have owned houses and I have owned 12 houses.” This is by far the only pillow to use if you don’t want to wake up with sore shoulders or neck. I have replaced all the pillows in my house with this pillow.
I have compressed discs in my neck, and I have spent hundreds of dollars over the past 6 months trying to find one that will help me sleep. Every pillow I bought caused me to wake up in even more pain than the night before!! The buckwheat pillow is life-changing!! I have slept through the night and wake up with no pain!!
I was leery to try another expensive pillow without some sort of trial period after being very let down by a different company's natural fiber pillow… I don't hear anything at all with the buckwheat! It does stay fresh and cool as well, but most importantly it actually holds my head/neck up and in place. Which allows me to actually get rest instead of always adjusting.
I've been a buckwheat pillow customer for the last 7 years and I can say that Circadian has the highest standards of quality paired with incredible customer service. Very very impressed and would not hesitate to send anyone their way.
I have spent years searching for a pillow that feels supportive and comfortable all night. I have finally found it. I absolutely love the Buckwool pillow. I removed a bit of the material to get it to exactly how I want it… I rarely wake up with neck pain now.
I find myself switching between the two and loving the feel of both. I haven't woken up with a sweaty head with either and that's an amazing feeling especially in the AZ summer. The buckwheat side is a lot quieter and more comfy/soft than others I've tried in the past.
I have tried at least 10 different pillows in the last 3 years. Nothing has worked out except for this wool pillow. I have chronic neck pain which has been greatly reduced. I am very happy with my new pillow.
I have pretty bad chemical sensitivity (housebound most of the time)… I try to only buy totally safe, non-toxic products. I found this pillow to be very safe and non-toxic, and the packaging was fragrance free which is always a huge plus.
I ordered this pillow to replace my very old (but beloved) down pillow and I'm so glad I did. It is heavenly!… I advise you to heed the recommendation given by the quiz. I ordered cotton initially despite the quiz giving me kapok as a result… the quiz was right.
The quality craftsmanship and materials is evident… when I asked if extra stuffing were available for the second one I'm using as a knee pillow, they not only pointed me to the right place on their site, but also created a new, smaller 1-lb. refill size based on my request.
