Long-staple organic cotton, hand-tufted in New Jersey with corner loops that tie into a duvet cover. GOTS Certified Organic through every layer. Cool to the touch from the first night.

This comforter has real weight to it and still breathes all night. That is the combination a down alternative is supposed to give you, and usually does not. Almost every down alternative on the market is filled with polyester batting, which is plastic, and plastic is what makes a comforter sleep hot and clammy by the middle of the night. This one is filled with organic cotton.
The cotton arrives as a cohesive layered pad rather than the loose clusters down is made of. Loose clusters drift into the corners unless they are trapped in sewn chambers. A layered pad can be tufted instead, so the cotton is anchored by hand at points across the whole comforter and stays where it was put for years.
Circadian sells this comforter as the insert, not as a finished bedspread. Corner loops at each end tie into the ties inside a duvet cover, which stops the cotton sliding to one end by morning. The cover takes the laundry and the cotton stays dry. We make the cover too, in the same organic cotton sateen duvet cover, so the two are cut to match.
Oregon Tilth certifies this comforter to the Global Organic Textile Standard, the cotton inside it as well as the sateen over it, under license GOTS-10229. An auditor walks the workshop and the supply chain every year. That standard is what keeps pesticide residue, formaldehyde, PFAS and microplastics out of something you sleep under for a third of your life.
The comforter weighs about 7.5 pounds at Twin, 12 at Queen and 13.5 at King, and the weight is printed on the size chart. Cotton is a plant, so this one is vegan. Under a cover, with the care below, it lasts 10 to 15 years.
Spot clean it and put it in the sun. A washing machine and a dry cleaner will both felt the cotton batting inside and break it down, so neither goes near it.
The sateen is woven in the United States from cotton grown in Texas, and the comforter is hand-tufted in New Jersey.

We choose every material and decide how much goes into each pillow, down to the side zipper you use to set the height. The same hands have been making pillows in this New Jersey workshop since 1981, and each one is sewn by hand, to order.
Plant or animal fibers only, with no chemical processing in the build. The material inside and the cover over it carry independent certification (GOTS for cotton and wool, OEKO-TEX for latex), and every input down to the thread is GOTS-approved.
Made by hand in a New Jersey workshop that has been making pillows since 1981
The list most bedding makers hope you never read. None of it is in a Circadian duvet.
Most duvets at this price are box-stitched or channel-sewn. Box stitches let the fill bunch in the corners. Channels let it migrate to one end. Both leave thin patches where the fill has moved away.
Hand-tufting is the older method. Each tie is a corner loop worked through the duvet by hand, holding the cotton in place without compressing it. The technique takes longer to do, and the anchor points hold the fill rather than leaving a seam to do the work.
Each Circadian duvet is tufted in our New Jersey workshop with corner loops across the surface. You can see them as small dimples on the surface, and feel them as gentle anchor points that keep the loft uniform from corner to corner.
Every Circadian duvet is GOTS Certified Organic end to end. The material inside and the shell over it are certified together under license GOTS-10229, issued by Oregon Tilth. The licence is renewed on an on-site audit every year. Most competitors certify only the shell.
Long-staple fibers are smoother, springier, and last years longer than the short-staple fibers in commodity duvets. Cotton is dense and even. It distributes weight across your body without clumping into pockets, and the long-staple fibers stay loftier longer than the short fibers in cheaper duvets. The duvet feels substantial and grounded.
A 300 thread count sateen weave, undyed and GOTS Certified Organic. The sateen float sits four yarns over one, which is what makes the surface smooth against skin while the weave stays tight enough to hold the fill in. Most brands in this category publish no thread count at all.
Cotton-wrapped thread holds every stitch and every tuft, and like every input that goes into the duvet it is GOTS-approved. It is what the Global Organic Textile Standard specifies for stitching that has to take tufting tension.
Hand-tied corner loops hold the fill where it was placed. Reinforced with a backstitch under the shell. Built to outlast the duvet itself.
Our duvets are cut for drape rather than to the mattress footprint, so they hang over the sides instead of riding up at the foot. King covers both King and California King beds. Queen covers Full and Queen. Twin covers Twin and Twin XL.
| Size | Dimensions | Fits | Weight |
|---|---|---|---|
| Twin | 72" × 90" | Twin and Twin XL beds, guest rooms, kids' rooms | ~7.5 lb |
| Queen | 92" × 96" | Full and Queen beds, couples who want generous drape | ~12 lb |
| King | 96" × 110" | King and California King beds, taller sleepers | ~13.5 lb |
Hand-tufted, so size can vary by half an inch. The extra length on every size is intentional. Standard duvet covers run on the small side and tend to leave the duvet exposed at the corners after a few washes.
Honest read of where each fill wins and where it loses. Heavier than down. More breathable than polyester. The right answer for anyone who runs hot but wants warmth on cold nights.
| Circadian Cotton | Down | Polyester / synthetic | Wool/cotton blend | |
|---|---|---|---|---|
| Allergens | No down, no dust mite habitat | Feather and dust mite allergens | No down or feathers | Low allergen risk |
| Chemicals | GOTS Certified Organic through every layer, no flame retardants or PFAS | Often treated for feather migration | Microplastic shedding, possible PFAS finish | Depends on the brand |
| Temperature | Cotton breathes well, sleeps cool in moderate weather, and gives you the option to add ... | Very warm, runs hot for some sleepers | Traps heat and moisture | Breathes, regulates well |
| Construction | Hand-tufted with corner loops | Baffle-box or sewn-through chambers | Box-stitched or channel-sewn, migrates over time | Varies; usually box-stitched |
| Lifespan | 10 to 15 years | 5 to 8 years before loft loss | 2 to 4 years before clumping | 5 to 8 years |
| Weight feel | Substantial, grounded | Light and lofted | Light and synthetic | Moderate |
Comparison reflects typical products in each category. Individual brands vary. Down wins on lightness; we don't pretend otherwise. We win where it matters more to most buyers: allergens, chemicals, construction, and lifespan.
You want the drape and softness of down. But real down sheds through the seams, clumps into cold pockets after a season, and carries the dander that sets off allergies. The fix the industry sells you is a "down alternative," which is almost always polyester, fine plastic fiber that mats down and gives off petroleum compounds.
So you pick between a feel that falls apart and a fake that is microplastic. Long-staple organic cotton gives you the drape without either.
Dense long-staple cotton drapes with a grounded weight and spreads evenly, without feathers, dander, or shedding through the seams.
Certified as a finished duvet, the material inside as well as the shell, so the duvet you pull to your chin all night carries no bleach, nothing dyed and no synthetic finishes.
Corner loops hold the fill so it will not clump into corners or leave cold spots the way down does after a season.
The comfort of down without the shedding, the clumping, the allergens, or the plastic. One duvet you can actually breathe next to, night after night, for years.
I'm allergic to down and most synthetic fills give me morning headaches. This is the first duvet I've owned that doesn't trigger anything. The weight feels right, the cotton breathes, the hand-tufting doesn't shift. There's nothing I'd change.
My Brooklinen down-alternative had started clumping at the bottom and going flat in the middle. This one weighs more, feels more substantial, and the tufts keep the fill exactly where it was placed. Worth the upgrade.
Switched from a polyester comforter that I'd had for years. The difference is real. The cotton breathes overnight. The polyester was making me sweat without realizing it. Three weeks in, I sleep deeper.

Most cotton comforters are bleached with chlorine, treated with formaldehyde resins to stop wrinkles, and finished with PFAS to repel stains. You spend eight hours a night under it, breathing what comes off it. Most brands that call a duvet organic certify the shell and stop there. Ours was certified as a finished duvet, the cotton inside it as well as the shell over it, so none of those compounds went near it at any stage. The cotton smells like cotton because that is all it is. It is filled and closed in a GOTS certified workshop in New Jersey that has been making natural bedding since 1981.
License GOTS-10229, issued by Oregon Tilth, held against the Global Organic Textile Standard and renewed on an on-site audit every year.
This is one piece of a bed. Here is the rest of it, cut from the same organic cotton in the same workshop.

Each duvet is hand-tufted in our New Jersey workshop with corner loops that hold the fill in place over years of use. The technique is older than sewn channels or box-stitching, and it doesn't migrate. The fill stays where it was placed.
Down compresses under your weight and clusters cold spots over time. Our cotton and wool fills stay loftier longer, distribute heat more evenly, and don't trigger feather allergies. They're also heavier than down, which a lot of people prefer for the weighted feel.
Yes. Both the cotton and wool duvets are full-weight three-season covers. The wool version handles colder rooms better because wool traps warm air without trapping moisture. The cotton version is best for people who want lofted warmth without overheating.
Cotton breathes well and is comfortable in moderate summers. Wool actively wicks moisture away from your skin, which is why it feels cool to hot sleepers even on warm nights. If you're in a climate that gets above 80°F at night, the wool duvet is the better choice.
Three sizes. Twin (72 by 90 inches) fits Twin and Twin XL beds and works well in guest rooms or kids' rooms. Queen (92 by 96 inches) fits Full and Queen beds with generous drape on both sides. King (96 by 110 inches) fits both King and California King beds, with extra length so the duvet covers your feet without riding up. All three are cut from the same long-staple GOTS Certified Organic fill.
No. The duvet is the insert, built to live inside a removable cover that you wash, with corner loops that tie into the cover so it stays put. We make an Organic Cotton Duvet Cover to go with it, sold separately.
Spot clean only. Neither duvet goes in a washing machine. The cotton duvet is spot clean and sun only, and it should not be dry cleaned either. The wool duvet is spot cleaned, aired in sunlight every few months, and dry cleaned only if heavily soiled. The cover you keep on it gets washed, not the duvet itself.
No. The wool is soft and springy, and it is contained inside an organic cotton sateen shell, so it never touches you. You won't feel the fibers through the cover.
Cotton is denser than wool, so the cotton duvet feels heavier per square inch. Most people read this as comforting rather than oppressive. Cotton runs about three pounds heavier than wool at Queen, and both feel substantial without weighing down on top of you.
10 to 15 years with normal use and a duvet cover. Hand-tufting outlasts sewn channels and box-stitching by a wide margin because there's no thread under tension that can wear through.
Yes. Both the cotton and the wool duvet are GOTS Certified Organic as finished duvets, the fill inside as well as the shell over it. The license number is GOTS-10229, issued by Oregon Tilth and renewed on an on-site audit every year. Every input down to the thread is GOTS-approved.

The Circadian Organic Cotton Duvet is a hand-tufted duvet insert filled with layers of long-staple organic cotton inside an organic cotton sateen shell, the down alternative without the polyester. It is GOTS Certified Organic as a finished duvet under license GOTS-10229, issued by Oregon Tilth. Cotton runs neutral, so it drapes with a grounded weight and stays cool to the touch in summer, then layers for warmth in winter. It is plant-based and vegan, and it is made to order in New Jersey.
The Circadian Organic Cotton Duvet suits sleepers who run neutral to slightly warm and want the weight of a traditional comforter without down, feathers or synthetic fill. It is the vegan choice of the two Circadian duvets. Hot sleepers and people with night sweats or dust-mite allergies are usually better served by the Organic Wool Duvet, which wicks moisture. If you want a duvet that feels substantial and stays cool to the touch, cotton is the one.
The Circadian Organic Cotton Duvet comes in three sizes. Twin is 72 by 90 inches and fits Twin and Twin XL beds. Queen is 92 by 96 inches and fits Full and Queen beds. King is 96 by 110 inches and fits King and California King beds. Cotton is a dense fill, so the Twin weighs about 7.5 pounds, the Queen about 12 pounds and the King about 13.5 pounds, roughly a pound heavier than the wool duvet in each size.
Spot clean and sun only. The Circadian Organic Cotton Duvet does not go in a washing machine and should not be dry cleaned either, because water and solvents mat the cotton layers inside. Blot any mark with a damp cloth, then air the duvet in the sun a few times a year. Keep a duvet cover on it and wash the cover instead, which is what handles the regular laundry.
The Circadian Organic Cotton Duvet is covered by the 60-night trial, the same as the pillows. Sleep under it for up to 60 nights, and if it is not right, email jacob@circadianrest.com and we send a prepaid return label. There is no restocking fee. The refund goes back to your original payment method within 3 to 5 business days of the duvet reaching the New Jersey workshop.
Every Circadian duvet is made to order in New Jersey, so the build comes first. Duvets leave the workshop in 7 to 12 business days, and the carrier adds 2 to 5 business days depending on how far you live from New Jersey. Checkout shows the arrival window for your address before you pay, and shipping is free within the contiguous United States. Express is $19 at checkout and moves your order to the front of the build queue.
The duvet is the insert, built to live inside a cover you wash. Circadian makes the Organic Cotton Duvet Cover in the same three sizes, Twin, Queen and King, with interior corner ties that catch the loops on the duvet so it stays put. The Organic Cotton Sheet Set, Fitted Sheet, Flat Sheet and Pillowcases are cut from the same 300 thread count organic cotton sateen, so the whole bed matches in cloth and color.
