Every Circadian pillow is designed in Washington, DC and handcrafted in our New Jersey workshop. The product specs, fill ratios, material sourcing, and adjustable-zipper system all originate from our DC headquarters. Manufacturing happens stateside by skilled workers who specialize in natural-fill bedding.
Plant or animal fibers only, with no chemical processing in the build. The fill and the cover carry independent certification (GOTS for cotton and wool fills, OEKO-TEX for latex), and every input down to the thread is GOTS-approved.

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 fill, the shell, the thread, and the dye process are all certified together under license GOTS-10229, issued by Oregon Tilth. The license number is publicly searchable on the GOTS database. 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 tight-woven cotton sateen that feels soft against skin and keeps the fill contained without trapping heat. GOTS Certified Organic, undyed, woven from the same long-staple cotton as the fill.
Cotton-wrapped thread holds every stitch and every tuft, and it is audited under the same license as the fill and the shell. 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 larger than the US standard so they drape over the sides of the mattress without 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 | ~10 lb |
| King | 98" × 110" | King and California King beds, taller sleepers | ~12 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 end to end, 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.
GOTS organic from fill to thread, so the duvet you pull to your chin all night carries no bleach, dyes, or 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 only the shell. Our GOTS certification covers the entire finished duvet, the fill, the shell, and every input down to the thread, so none of those compounds went near it at any stage. The cotton smells like cotton because that is all it is.
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 (98 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, designed to live inside a removable cover that you wash. We recommend organic cotton percale or sateen covers; we don't currently sell our own.
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. Long-staple wool is soft, springy, and contained inside an organic cotton sateen shell. 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 a pound heavier than wool at the same size, 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 wool duvets are GOTS Certified Organic. The fill and the shell are certified organic, and every input down to the thread is GOTS-approved. The license number is GOTS-10229, certified by Oregon Tilth and publicly searchable.
