Organic Wool Duvet

$415.00

Long-staple New Zealand wool, hand-tufted in New Jersey with dumbbell knots every 20 centimeters. GOTS Certified Organic from fill to thread. Wicks moisture so partners with mismatched temperatures sleep through the night.

Pair it with the matching organic pillow and save 15% automatically at checkout.

Heavy enough for winter, dry enough for summer, and naturally kind to allergies. Long-staple GOTS Certified Organic wool wicks 30% of its weight in moisture so you stop waking up clammy, and the same dry, lanolin-rich fiber resists dust mites on its own, with no treatment.

One duvet works year round because wool regulates temperature actively. It traps warm air when the room cools and releases moisture vapor when your body heats. Hand-tufted in New Jersey with twisted-cord ties that hold the fill in place for years, so the wool can't shift, clump, or settle to one side.

Sleep on it for 60 nights. If it's not right, send it back free for a full refund. Return policy

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 cover, fill, thread, and dye process all carry independent certification (GOTS for cotton and wool fills, OEKO-TEX for latex).

Construction

Hand-tufted in New Jersey. The old way of building a duvet.

Most duvets at this price are box-stitched or channel-sewn. Both fail predictably. Box stitches let the fill bunch in the corners. Channels let it migrate to one end. After two seasons you're sleeping under a duvet with cold spots.

Hand-tufting is the older method. Each tie is a small twisted-cord knot worked through the duvet by hand, holding the wool in place without compressing it. The technique takes longer to do. It outlasts both alternatives by a decade.

Each Circadian duvet is tufted in our New Jersey workshop. The ties sit at 20-centimeter intervals across the duvet. 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.

What's inside

Four organic materials. One license number. Nothing else.

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.

01
Long-staple organic wool

Long-staple fibers are smoother, springier, and last years longer than the short-staple fibers in commodity duvets. Wool is springy and resilient. It holds shape under your body weight, breathes when your skin warms, and wicks moisture vapor instead of trapping it. The duvet feels substantial without feeling heavy.
02
Organic cotton sateen shell

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.
03
Organic cotton thread

GOTS Certified Organic cotton thread for every stitch and tuft. No polyester thread anywhere in the duvet. This is the detail almost every competitor skips because cotton thread is more expensive and harder to source.
04
Twisted-cord tufts

Hand-tied at 20-centimeter intervals to hold the fill where it was placed. Reinforced with a backstitch under the shell. Built to outlast the duvet itself.

Sizing

Three sizes. Cut generously for full coverage.

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	~3 lb
Queen	92" × 96"	Full and Queen beds, couples who want generous drape	~6 lb
King	98" × 110"	King and California King beds, taller sleepers	~8 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.

Comparison

How it compares.

Honest read of where each fill wins and where it loses. Heavier than down. Lighter than wet cotton. The right answer for hot sleepers and night sweaters.

	Circadian Wool	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	Wool wicks up to 30% of its weight in moisture, releasing it as vapor so the surface st...	Very warm, runs hot for some sleepers	Traps heat and moisture	Breathes, regulates well
Construction	Hand-tufted with twisted-cord ties	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.

I run hot. My wife runs cold. We've been arguing about bedding for six years. The wool duvet ended the argument. She's warm because wool holds heat. I'm dry because wool wicks moisture. No more thermostat war.

Daniel W. Verified buyer

Used it through winter AND summer

Bought this for winter and was prepared to swap it for something lighter in May. Never did. The wool regulates temperature so well that the same duvet works through August. Pays for itself in not needing two duvets.

Lanolin scent goes away

First night the faint wool smell was noticeable. Like the inside of a fresh wool sweater. By night five it was gone. After that it just smells clean and the duvet feels like it's been part of the bed forever.

Common questions about our duvets

Each duvet is hand-tufted in our New Jersey workshop with twisted-cord ties 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. For the cotton duvet, you can occasionally machine wash on cold gentle and tumble dry low if needed. The wool duvet should not be machine washed; wool needs to be 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 end to end. That covers the fill, the shell, the thread, and the dye process, all certified together. The license number is GOTS-10229, certified by Oregon Tilth and publicly searchable.
