Your head rests on organic cotton all the way through, not on an organic cover with something else inside. Of more than 25 brands selling an "organic cotton pillow," only 10 fill it with cotton. The whole pillow is GOTS Certified Organic, so chlorine bleach and formaldehyde stay out of the cotton inside as well as the cover. It is naturally hypoallergenic, too. GOTS is the Global Organic Textile Standard.

Cotton is packed firm and full, so your head rests on top of it instead of sinking into a hole. Your head stays level with your shoulders, and the pillow is still holding it there in the morning.

Lots of us grew up on a plump cotton pillow. This one feels like that, firm and simple, and it is filled and sewn by hand in a GOTS certified workshop in New Jersey.
A cotton pillow holds its shape for years. Most pillows start out fine and slowly flatten, until one morning you wake up in a divot and go buy another one. Cotton is packed tightly enough to resist that. It is the most tightly packed of the fibers we use, denser than wool or kapok, so your head presses it down slowly and evenly over months and years instead of weeks. The support you feel the first night is the support you feel a year later.
The density comes from the length of the fiber. The cotton inside this pillow is long-staple, averaging about 1.25 inches, roughly a quarter longer than the short-staple cotton most pillows are filled with. Longer fibers spin into stronger threads. They shed less lint, they hold their height under weight, and they work their way out through the cover far more slowly than short ones do. Long-staple cotton needs a longer growing season, more careful picking and slower processing, which is why most pillow makers reach for short-staple or blend in synthetic fiber to bring the cost down.
Plenty of pillows are sold as organic cotton, and on most of them the certificate covers the outer fabric and stops at the seam. The cotton your face is pressed into all night was never part of the audit. This pillow is certified inside and out, the cotton inside it as well as the cover over it, under the Global Organic Textile Standard. An auditor comes to the New Jersey workshop every year and walks the supply chain behind it. The license is GOTS-10229, issued by Oregon Tilth.
Conventional cotton pillows are commonly bleached with chlorine, treated with formaldehyde resins to stop wrinkles, and finished to repel stains. You breathe the air a few inches above all of that for eight hours a night. The standard keeps every one of those out of this pillow, inside and out.
A simple rhythm keeps the density where you want it. Add cotton through the zipper on the short end if it ever sits too low, work it loose by hand once a month so the fibers spread out again, and air it in the sun a few times a year. That is how a cotton pillow stays supportive for years instead of months.

Waterproof pillow protector: 6 things to check before buying
Researchers have gone looking for the right pillow height and not found one. A 2021 review in Healthcare pulled together the studies on how height gets chosen and reported no optimum for back or side sleeping. It also found that the height which works for a person does not track the measurements of their head or their neck. So there is no number anyone can calculate for you, and a sealed pillow that arrives at one height has guessed.

Three certification logos turn up on bedding labels and they answer three different questions. GOTS vs OEKO-TEX vs GREENGUARD: which to trust explains what each one covers and where each one stops.

Oregon Tilth, Inc. certifies that
this organic cotton
pillow
License Number GOTS-10229
is certified in conformity with the
Global Organic Textile Standard (GOTS) Version 7.0
Audited on site every year by Oregon Tilth
Most cotton pillows are bleached with chlorine, treated with formaldehyde resins to stop wrinkles, and finished with PFAS to repel stains. You spend eight hours a night breathing the air six inches above whatever is left. Most brands that call a pillow organic certify the outer cover and stop at the seam, which leaves the cotton your face is pressed into outside the audit. On ours the whole pillow is certified, the cotton inside it as well as the cover over it, so none of those compounds went near it at any stage. It is sewn shut in a GOTS certified workshop in New Jersey, audited on site every year, which is the step most organic labels leave out.
| Size | Dimensions | Weight |
|---|---|---|
| Standard | 20" × 26" | About 3.3 lb |
| Travel | 12" × 16" | About 1 lb |
| Queen | 20" × 30" | About 3.6 lb |
| King | 20" × 36" | About 4.8 lb |
Most pillows come at one fixed height, so you sleep at a height that was never set for your body, and your neck and shoulders pay for it in the morning. Every Circadian pillow arrives full instead. You set the height on night one, take a little more out over the trial, and the pillow you've shaped is yours to keep.
Side sleepers
Cotton is the most tightly packed of our fiber fills, so a full pillow fills the gap between your shoulder and your ear and holds that height for years.
Back sleepers
Take a few handfuls of cotton out through the zipper until your chin sits level and the space behind your neck is filled in.
Stomach sleepers
Take out about half, so your head and shoulders sit close to level with the mattress.
Keep the cotton you take out in a clean bag, and put it back any night you want more height.
About 30% more inside than most people keep, so you can shape it to your own neck.
If the height feels off a few weeks in, put some back or take more out.
Not for you after 60 nights? Full refund, and no restocking fee.
Refill cotton sold separately if you want to bring the height back up after years of use.

Inside the pillow
The fiber inside this pillow is long-staple organic cotton. That phrase carries the entire design.
Long-staple cotton packs tight, so it holds your head up instead of letting it sink.
Cotton fiber lets air through, so heat does not build up the way it does in foam. The cover is organic cotton sateen.
It skips the chlorine bleach, optical brighteners and polyester blend most pillow cotton gets. Cotton resists flame on its own, so it needs no chemical flame retardant.
Each fiber is 1.25 inches or longer, roughly a quarter longer than standard short-staple cotton.
Longer fibers spin into stronger threads and lock together into tighter, more resilient clusters. Under your head, that translates into a pillow that compresses slowly and evenly over months and years, not weeks. The trade-off is cost. Long-staple cotton requires longer growing seasons, more careful picking, and slower processing. Most pillow makers reach for short-staple cotton or blend in synthetic fiber to cut the cost. We do not. The cotton inside the cover is the same cotton that came off the boll, without the chlorine bleach, optical brighteners or polyester blend most pillow cotton gets. Cotton resists flame at the fiber level, so it needs no chemical flame retardant.

She unboxes the pillow, opens the zipper to show the cotton inside, then makes the bed.
I spend as much time outside as I can. I wanted my eight hours in bed to be just as clean. Most pillows are foam and polyester, so I made one from plants and wool instead. You open it and set the height to fit your neck. Every pillow is sewn by hand in New Jersey and filled to order.

Yes, the Organic Cotton Pillow is firm, the most tightly packed of our fiber pillows, so your head rests on it instead of sinking in. It arrives full, and taking cotton out through the zipper makes it lower and a little softer. Go slowly, a handful at a time, and keep what you take out in a bag in case you want it back. If you want a pillow you can bunch up under your cheek, the Organic Wool Pillow is springier and lighter, the next step down in firmness.
Yes. Side sleepers need a taller, firmer pillow to fill the gap between the shoulder and the head. The pillow arrives full, so most side sleepers keep all the cotton in for the extra height and firmness, and take a little out through the zipper only if it feels too tall.
Cotton compresses gradually rather than collapsing, but it is a natural fiber, so it does settle. Most customers get two to four years before the cotton needs replacing, against six to twelve months for a typical synthetic pillow. The Circadian Organic Cotton Pillow has a zippered cover and refill packs are sold separately, so you can bring the height back whenever it settles.
Memory foam conforms around your head and traps heat. Organic cotton is denser and more supportive, and breathes better because air moves through the fiber.
A Standard weighs about 3.3 pounds with its cover on when it arrives full, and less once you take some cotton out. The weight is moderate enough that you will not notice it during sleep, but substantial enough to stay in place on your bed.
Yes, especially for chemical sensitivities. The cotton inside and the cover over it are certified organic inside and out and audited every year, so formaldehyde finishes, PFAS stain repellents and off-gassing are not part of it. For dust mite allergies specifically, the wool pillow may be a better fit, because wool keeps the air at your face too dry for dust mites.
Regular cotton is one of the most heavily sprayed crops in farming, and most pillows made from it are then bleached, softened with formaldehyde and coated with the stain repellents people now avoid as PFAS. Organic cotton is grown on certified organic farms from non-GMO seed. The Circadian Organic Cotton Pillow is certified organic through every layer, the cotton inside and the cover over it, and an independent auditor checks it every year.
GOTS stands for the Global Organic Textile Standard, the leading standard for organic textiles. On most organic pillows it covers the outer fabric alone. On the Circadian Organic Cotton Pillow it covers the finished pillow: the cotton inside, the cover over it, and the workshop that sews them. An auditor checks it on site every year, which is how chlorine bleach, formaldehyde softeners and PFAS stain repellents stay out of it. The license is GOTS-10229, issued by Oregon Tilth.
An organic cotton pillow lasts several years with proper care. Cotton compresses slowly, and when it settles you open the zipper and add cotton to bring the height back. Most customers use theirs for two to four years before the cotton needs replacing.
You can remove the organic cotton cover through the zipper and wash it in cold water with a gentle detergent, then let it air dry. The cotton inside should not go in the washing machine, because water packs it into clumps.
The Circadian Organic Cotton Pillow. It is GOTS Certified Organic inside and out, license GOTS-10229 issued by Oregon Tilth, which covers the cotton inside as well as the cover. It is the densest of our fiber pillows, denser than wool or kapok, with the firm, traditional feel of a good hotel pillow. Most pillows are bleached, softened with formaldehyde and filled with polyester. This one is long-staple organic cotton from the cover to the core, and you set the height yourself through the zipper on the short end.
