5 to 200 pounds, USA-grown and pre-polished
The same pre-polished, air-jet cleaned hulls that go into our own pillows, sold in bags up to 200 pounds. Buy them because you are making something, or because a pillow on your bed has settled and you want the height back.
We sell buckwheat hulls in 5, 10, 20, 50, 100 and 200 pound bags. They are grown in the United States and pre-polished, which breaks the pyramid edges into flat sides. Then they are cleaned by air jet rather than by chemicals, and UV sterilized before bagging. Nothing is roasted and nothing is added. For sizing, one of our filled standard pillows weighs about 10 pounds, and nearly all of that is hulls. So a 50 pound bag is roughly five standard pillows, and a 200 pound bag is roughly twenty. If you need more than 200 pounds at a time, write to us rather than adding bags to a cart.
Most people buying at the top of this range are making their own. If you would rather we did the sewing, the two pillows we put these hulls into are here as well.
One product, six bag sizes. The 5 and 10 pound bags top up a pillow that has settled. The 50, 100 and 200 pound bags are what makers, workshops and studios order.
Best for refilling, or filling something you are building yourself
The same hulls inside an organic cotton cover with a full-length side zipper, so you can set the height from the first night. This is what these hulls are for when we use them ourselves.
Best for anyone who wants the fill without the sewing
A buckwheat chamber on one side and an organic wool chamber on the other, divided by an internal cotton wall. It is the answer for people who find pure hulls too firm against the cheek.
Best for the buckwheat hold with a softer second side

Buckwheat hulls look the same in every photograph, which is why the market is full of bags that arrive dusty, loud, or full of broken pieces. What separates them is what happened between the mill and the sack.
1
Sharp points, hard edges, and a lot of chaff and dust in with them straight off the mill.
2
Raw hulls are cheaper because nobody has spent a step on them, and they are what most sellers list.
3
That catching is the crackle people remember, and the dust is what makes a new bag smell and shed for weeks.
4
Pointed edges chip against each other, so raw hulls turn to powder at the bottom of the bag sooner.
Ours are pre-polished, which breaks the pyramids into flat sides, and cleaned by air jet, which lifts the chaff and dust out before bagging. That is two extra steps and it is the whole difference in the bag.
A raw buckwheat hull is a rough pyramid with pointed edges, and those edges catch every time the fill moves. Pre-polishing tumbles the hulls until one side flattens, so they slide against each other rather than snagging, and movement noise drops by up to 68 percent.
The same step is why they last. A flat-sided hull has less to chip off, so a bag of ours breaks down to dust more slowly than a bag of raw hulls does. If you are filling something you intend to keep, that is the part worth paying two extra steps for.
The reliable way to size an order is to weigh what you are filling, or to weigh what came out of it. Our own pillows are a useful yardstick, because they are filled to a known weight. A standard at 20 by 26 comes in around 10 pounds. A queen at 20 by 30 is around 13, a king at 20 by 36 around 15, and a travel at 12 by 16 around 2.5. Almost all of that weight is hulls.
So a 50 pound bag is roughly five standard pillows, a 100 pound bag roughly ten, and a 200 pound bag roughly twenty. Order a little over what the arithmetic says. Hulls settle in the first weeks of use, and a maker who runs out halfway through a batch waits on a second shipment.
Dry hulls hold no moisture for mold to work with, which is why they keep almost indefinitely in a sealed bag away from damp. Wet hulls swell, break down and go musty, and they cannot be dried out again once they are inside a sewn cover. Never wash them and never put them near a machine.
If a bag has been sitting a while and smells flat, spread the hulls out in direct sun for three or four hours and they come back. That is the whole maintenance routine. There is no cleaning step beyond it and nothing to add.
At 5 pounds a bad bag is an annoyance. At 200 pounds it is a pallet of something you cannot use, so these are the questions worth asking of any seller.
| What to check | Circadian | Typical bulk hulls |
|---|---|---|
| What happens after milling | Pre-polished, so the pyramid edges become flat sides | Usually raw, straight off the mill with the edges intact |
| How the dust is removed | Air-jet cleaned before bagging | Often screened only, and sometimes not at all |
| Sterilization | UV sterilized, with no chemical treatment at any stage | Frequently untreated, or heat-treated instead |
| Where they are grown | Grown in the United States, and we will tell you the state | Commonly imported with no country of origin stated |
| Noise in use | Movement noise down by up to 68 percent against a raw hull | The crackle buckwheat is known for |
| Largest bag | 200 pounds, with larger orders quoted directly | Often 25 or 50 pounds as a ceiling |
| Roasting | None. Roasting makes hulls brittle and leaves a burnt smell | Roasted hulls are widely sold as a cleaning shortcut |
| Who fills pillows with them | We do, in our own workshop, which is where the spec came from | Most sellers are distributors rather than makers |
Take the 5 pound bag. Topping up takes far less than people expect. Add a little through the side zipper, lie down, and check that your head sits level. Add more only if you need it.
Buckwheat Hulls ›Ten pounds fills a standard and fifteen fills a king. The 10 or 20 pound bag covers one pillow with something left over for the settling that follows.
Buckwheat Hulls ›Start at 50 pounds to test how our hulls behave in your pattern, then step up to 100 or 200 once you know your yield per piece. The polish changes how the fill moves, so test before you commit a season to it.
Buckwheat Hulls ›Then take the pillow we fill with these hulls. It arrives full with a full-length side zipper, so the first thing you do is take hulls out until your head sits level with your spine.
Buckwheat Pillow ›About 10 pounds for a standard at 20 by 26, 13 for a queen at 20 by 30, 15 for a king at 20 by 36 and 2.5 for a travel at 12 by 16. Those are the filled weights of our own pillows and nearly all of that weight is hulls. Buy a little over the figure, because hulls settle in the first few weeks.
200 pounds in a single bag, which is the biggest size on the site. If you need more than that at a time, write to us instead of stacking bags in a cart and we will sort out the order and the freight.
They are grown in the United States and go into the bag with no chemical treatment at any stage, cleaned by air jet and sterilized with UV light. Our finished-product organic certification covers the cotton and wool goods rather than the hulls. So we describe these by exactly what is done to them, rather than borrowing paper that does not apply.
Buckwheat is a seed rather than a grain, and it has no botanical relationship to wheat. The plant is a relative of rhubarb and sorrel, and the hull is the husk around its seed. That said, buckwheat is itself an allergen for a small number of people, so if you react to buckwheat as a food, do not fill anything you sleep on with it.
An unpolished hull keeps the pointed pyramid shape it had at milling, so the edges catch on each other and that catching is the noise buckwheat is known for. A pre-polished hull has been tumbled until one side flattens, so they slide instead. Ours are pre-polished, which cuts movement noise by up to 68 percent and slows how fast the hulls break down.
The 50, 100 and 200 pound bags are priced for people buying at that scale and you can order them straight from the site. For standing orders, repeat volume or anything above 200 pounds, write to us and we will quote it properly rather than have you work around the cart.
No, and this is the one rule worth being firm about. Water swells the hulls, breaks them down and leaves them musty, and they cannot be dried out again inside a sewn cover. Wash the cover instead and give the hulls three or four hours in direct sun if they need freshening.
Three to five years in a pillow that gets slept on nightly, and far longer than that sitting in a sealed bag somewhere dry. What ends their life is compression rather than dirt. They break down slowly into a finer material, the height drops, and you top the pillow back up.
Pillows and cushions mostly, then meditation seats, neck and shoulder wraps, positioning supports, and props for studios and clinics. The common thread is wanting a fill that takes a shape under weight and then holds it, which is something no fiber or foam does in the same way.
Not when they are clean and dry. Ours are UV sterilized before bagging and dry hulls hold no moisture, so there is nothing to draw anything in. The problems people describe almost always trace back to hulls that got damp, or to a cheap bag that arrived with chaff and mill debris still in it.
Bags up to 200 pounds go straight through the site. Anything larger, or a repeating order, is worth an email so we can quote the freight properly and hold stock for you.
See the bag sizesIf you've sent more pillows back than you've kept, you're our customer.
The three-star ones are in there too.
“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.
