Organic cotton, waterproof, and quiet
A natural fill does not wear out from being slept on. It wears out from what soaks into it, which is skin oil and the moisture your head gives off every night. A protector is the cheapest thing you can do about that.
Ours is a zip-around protector with organic cotton on both faces and a thin waterproof film between them, made in five sizes from travel up to body. It is GOTS Certified Organic inside and out under licence GOTS-10229, audited yearly by Oregon Tilth, and it also meets GreenGuard Gold. The film is bio-based rather than a vinyl sheet, so it does not crackle when you move and it does not feel like plastic under your ear. We recommend one on every pillow, and we push hardest on the kapok and the wool. Those two fills hold moisture, and a protector is what keeps it off them.
The protector seals the pillow. The case is what your face touches. People often buy one and assume it does both, and it does not.
Organic cotton either side of a waterproof film, zipped all the way around the pillow. It goes on first, under the pillowcase, and it is the only layer here that stops anything reaching the fill.
Best for every pillow you own, and the kapok and wool above all
300 thread count long-staple organic cotton sateen with a plain slip-on opening, sold as a pair. Breathable enough that it does not undo the pillow underneath, which a synthetic case will.
Best for the layer between your face and the protector
Body pillows do not fit ordinary cases, and a case that stops short leaves the last foot of the pillow bare. Same sateen, same plain hemmed opening, in two lengths.
Best for anyone who owns a body pillow

Ask people why they replaced their last pillow and most of them say it went flat. Ask what changed first and the answer is usually that it started to smell, or it went yellow, or it felt heavy.

Everybody does it, warm sleepers more than most, and it goes straight down into whatever is under your head.
2
Oil passes through a cotton case in a way water alone does not, and it does not evaporate back out the way water does.
3
Wool and kapok are absorbent by nature, which is part of why they feel good, and it is also why they are the two that suffer most from this.

You can wash a cover. You cannot wash loose wool, kapok or cotton fill without matting it, and buckwheat hulls must never get wet at all.
A protector moves the whole problem up one layer, onto something you can put in the machine. That is the entire idea, and it is why we would rather sell you one than sell you a replacement pillow in two years.
The reason most people have given up on protectors is the noise. The cheap ones are a cotton face laminated to a vinyl backing, and vinyl is stiff, so every time you turn your head you hear it. Within a week the protector is in a drawer.
Ours uses a thin bio-based film bonded between two organic cotton faces. It moves with the cloth instead of resisting it, so there is nothing to crackle and nothing that reads as plastic under your ear. It also breathes, which a solid vinyl backing does not, so the pillow underneath can still move air.
Plenty of protectors are really a slip cover with an opening at one end, which leaves a gap at exactly the point where your pillow gets handled most. Ours closes with a zipper that runs around the pillow, so the fill is enclosed rather than covered.
That construction does a second job. A fully closed encasement is the recognised way to shut dust mites out of a pillow. It works on bed bugs for the same reason. Nothing gets in and nothing gets out.
Most organic claims in bedding are made about a fabric before anyone sews it into anything. Ours is GOTS Certified Organic inside and out, under licence GOTS-10229, with a yearly on-site audit by Oregon Tilth. One thing to know before you go looking for it: the licence is held by the workshop that sews our bedding, so their company name is what sits on the record rather than ours.
The certification carries a second benefit that people rarely connect to it. GOTS prohibits PFAS as an input and verifies residues below 25 parts per billion, and PFAS is the usual way a textile is made water resistant. Nothing of the kind is intentionally added here at any stage. The protector also meets GreenGuard Gold, which is a limit on what a product gives off into the air of the room.
Six things decide whether a protector is still on the pillow a month after it arrived, and only one of them is whether it keeps water out.
| What matters | Circadian | Typical waterproof protector |
|---|---|---|
| The waterproof layer | A thin bio-based film bonded between two cotton faces | Usually a vinyl or polyurethane backing laminated to one face |
| Sound when you move | None. The film flexes with the cloth | The crackle that gets the protector taken off again |
| What touches your face | Organic cotton on both sides | Frequently a polyester face, or the backing itself |
| How it closes | A zipper the whole way around the pillow | Often an open end or an envelope flap |
| Certification | GOTS Certified Organic inside and out, plus GreenGuard Gold | Commonly a fabric-level claim, or none at all |
| Water repellency chemistry | No PFAS intentionally added, residues verified below 25 parts per billion | PFAS treatments are still common and rarely disclosed |
| Breathability | Air still moves through, so the fill underneath keeps working | A solid backing seals the pillow and traps heat |
| Sizes offered | Travel, standard, queen, king and body | Usually standard and king only |
Start with the protector and do not wait. Those two fills are absorbent by design, which is what makes them comfortable and what makes them the fastest to age without something between them and you.
Waterproof Pillow Protector ›Worth it for one reason above all others. A spill that reaches the hulls is the one accident you cannot wash out, because water ruins hulls and they cannot be dried inside a sealed cover.
Waterproof Pillow Protector ›Take the protector in the size of every pillow on that bed. It is the difference between stripping a bed at two in the morning and stripping a bed and buying a pillow.
Waterproof Pillow Protector ›Then the pillow underneath is working against a barrier. A synthetic case holds moisture at the surface instead of letting it move away, which is the opposite of what a natural fill is doing.
Organic Cotton Pillowcases ›They extend the life of the fill, which is the part that gives out. Skin oil and moisture pass straight through an ordinary pillowcase. Once they are in a loose natural fill you cannot get them out again, because washing mats cotton, wool and kapok, and it ruins buckwheat hulls outright. A protector keeps all of that on a layer you can put in the machine.
Ours is not, and the reason is what the waterproof layer is made of. The crackle people remember comes from a vinyl backing, which is stiff and does not move with the cloth. Ours is a thin bio-based film bonded between two organic cotton faces, so it flexes rather than resisting and there is nothing to hear when you turn over.
A sealed one does. Anything with a solid backing stops air moving and the heat has nowhere to go, which is the second reason protectors end up in a drawer. Ours breathes, so the pillow underneath carries on moving air and moisture the way it was built to.
The useful question is whether the protector fully encloses the pillow. A zip-around encasement is the recognised way to keep dust mites out of a fill, and to stop the ones already in your bedding from settling into it. Ours zips the whole way around rather than closing with an open end. The outer faces are organic cotton with no PFAS intentionally added, so there is nothing on the surface to react to either.
Yes. It is GOTS Certified Organic inside and out under licence GOTS-10229, audited yearly on site by Oregon Tilth. That is a stricter claim than the usual one, which is made about a fabric rather than the thing that gets sewn from it. It also meets GreenGuard Gold for what it gives off into the air of the room.
Five: travel at 12 by 16, standard at 20 by 26, queen at 20 by 30, king at 20 by 36 and body at 20 by 72. Match the protector to the pillow rather than to the case. One that is too big bunches inside the case, and you feel every fold of it.
Before. The protector goes on the bare pillow and zips shut, then the pillowcase goes over the top of it. That order means the case takes the daily wear and the washing, and the protector only has to be washed occasionally.
Every month or two is plenty if there is a pillowcase over it doing the daily work. Wash it cool and hang it to dry, and keep it away from high heat in a dryer, which is hard on any waterproof layer. Wash it straight away if anything is spilled on it.
A pillowcase and a protector are not the same layer. Cotton is absorbent, which is the point of it, so a case takes moisture and oil straight through to the fill rather than stopping them. The case is what your face touches and the protector is what keeps the pillow clean.
Kapok and wool, then cotton. Kapok and wool are absorbent by nature, so they take on moisture readily and they are the two fills we push hardest on. On a buckwheat pillow the argument is different and just as strong. Hulls must never get wet. A protector is what stands between a spilled glass and a pillow you have to empty out.
A protector costs a fraction of the pillow it is looking after. It is the one thing we would put on every bed in the house before anything else. Free shipping. Handmade in our New Jersey workshop.

“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.
