60-Night Trial
You have 60 nights to sleep on it, adjust the loft, and decide if it belongs on your bed. Pull pieces out, add them back, work out your preferred height across the first week. If after 60 nights you decide this is not the right pillow for you, send it back. Full refund. No restocking fee, no explanation needed.
Free Shipping & Returns
Free shipping, free returns. Most orders arrive in 4 to 7 days. Latex is unfamiliar to most people, and the only way to evaluate it is to sleep on it for real. We'd rather pay for shipping than have you wonder.
Tree-Tapped Dunlop Latex (OEKO-TEX Standard 100 Class 1)
The latex starts as sap from Hevea brasiliensis rubber trees, harvested through shallow downward cuts in the bark, similar to tapping maple trees. The sap is processed using the Dunlop method, which whips the latex into a froth, pours it into a mold, and steam-cures it into a dense, open-cell block. We break the block into pieces, which is what gives the pillow its adjustability and continuous airflow between fragments. The fill carries OEKO-TEX Standard 100 Class 1 certification (the strictest tier, the same standard used for products made for direct infant skin contact), meaning it has been independently tested for over 100 harmful compounds including PFAS, formaldehyde, heavy metals, and pesticide residue. The rubber-tree source is FSC-certified.
Adjustable Fill (Zipper Access)
The Talalay latex inside is broken into small pieces that are easy to work with. Unzip the side, scoop pieces out over a wide surface if you want a softer or lower pillow, or add them back when you want more loft. Each handful changes the feel by a noticeable amount. The whole adjustment takes about three minutes. Solid latex blocks ship at one fixed firmness. This one adjusts to your neck.
Designed in DC · Handmade in New Jersey
Each pillow is filled by hand because the amount of Dunlop latex needs to be precise. Too much and the pillow ships too tall to fit most necks. Too little and it lacks the support that makes natural latex comfortable. Our team fills, weighs, and checks each one before sealing it.
Naturally Cooling
Dunlop latex has an open-cell structure that lets air move through the fill continuously, the way it moves through a sponge. Heat does not accumulate against your skin. The smaller latex pieces inside the cover leave air gaps between them that move heat away as you sleep, keeping the surface cool through the night. No gel layer, no phase-change material, just structural airflow.
Tapped from rubber trees the way maple syrup gets tapped. The latex sap comes out of Hevea brasiliensis trees through a shallow downward cut in the bark, gets whipped to fold air in, then poured into a mold and steam-cured into a block of pure rubber. We break that block into smaller pieces and put them inside an organic cotton cover so you can adjust the loft to your neck and sleep position. Pull pieces out for a lower profile. Add them back when you want more height.
Under your head, the latex gives firm, supportive loft and holds its shape through the night. Air moves through the open cells continuously, so the surface stays cool. The pieces conform to your neck without sinking flat, and the structure rebounds as you move.
This is Dunlop latex, made by hand at our New Jersey workshop from pure rubber sap with no synthetic blend. The finished latex carries OEKO-TEX Standard 100 certification at Class 1, the strictest tier in the program, which is tested to the same safety threshold as products designed for direct contact with infants and babies. The rubber-tree source is FSC certified (Forest Stewardship Council) on the upstream plantations in Sri Lanka. The cotton cover that wraps it is organic. The thread is undyed.
A faint rubber scent in the first three to seven nights is the trade-off worth knowing about. It clears completely as the latex airs out. Latex allergy sufferers should choose a different fill.
5
I've owned three latex pillows over the years and this is the first one I'd buy again. It's supportive. It runs cool. Being able to pull pieces out to lower the loft is the kind of thing I didn't know mattered until I had it.
Cool every night
I sleep hot. This pillow runs cool. The pieces have space between them and air moves through. Best summer pillow I've owned.
Inside the pillow
Tree-tapped Dunlop latex.
Dunlop latex begins as sap from Hevea brasiliensis rubber trees. A shallow downward cut in the bark opens the vessel network, the sap collects, and the tree heals to be tapped year after year for decades. Maple syrup harvesters work the same way.
The sap is whipped to a froth, poured directly into the mold, and baked until the open-cell structure sets.
Under your head, Dunlop latex gives firm, supportive loft and holds its shape without sinking. The open-cell structure lets air move through the fill continuously, keeping the surface cool through the night. We break the latex into smaller pieces and put them inside an organic cotton cover so you can adjust the fill to your neck and your sleep position. A solid block of latex would lock you into whatever firmness arrived in the box.

From the founder
Built because nothing on the market worked.
I'm Jacob, founder of Circadian. Every pillow I tried either flattened in three months or hid a list of chemicals you'd need a glossary to read, so we built one that doesn't do either.

Spine alignment · Tree-Tapped Latex
Three sleepers, three pillow heights.
Your spine stays neutral when the pillow fills the gap between head and mattress. That gap is different for back, side, and stomach sleepers.
Best for
Back & side
Latex is best for back and side sleepers because the Dunlop latex pieces give firm, supportive loft that holds its shape under your head. Stomach sleepers can pull fill through the side zipper, but the pieces never compress flat. If you sleep face-down, kapok or cotton lays lower.
Stomach
A high pillow tips your head back and overextends your neck. Most stomach sleepers want very little loft, or none.
Remove most of the fill so your head and shoulders sit close to level with the mattress.
Back
Supports the natural curve of your neck so your chin sits level and the small space behind your neck is filled in.
Remove fill a handful at a time until your head sits level with your shoulders.
Side
Fills the gap between shoulder and ear so your spine runs in a single horizontal line from skull to hip.
Keep most of the fill until your ear, shoulder, and hip stack along one straight line.

What's not in the pillow.
Most pillows labeled 'latex' are synthetic latex. That is petroleum-based foam that off-gasses volatile compounds and traps heat. Our latex is natural Dunlop latex, tapped from Hevea brasiliensis rubber trees the way maple syrup is tapped. The sap is whipped, poured into a mold, and baked until the open-cell structure sets. We break the latex into smaller pieces so the loft adjusts and air moves through the gaps between them. OEKO-TEX Standard 100 means the finished latex has been tested for over 100 harmful compounds including PFAS, formaldehyde, heavy metals, and pesticide residue. The cover is organic cotton.
Frequently asked questions
What is the difference between Talalay and Dunlop latex in a pillow?
Dunlop latex is whipped, poured into a mold, and steam-cured, resulting in a dense, springy, open-cell material. Talalay latex adds vacuum-sealing and flash-freezing steps, producing a lighter, fluffier feel. The Circadian Tree-Tapped Latex Pillow uses Dunlop latex broken into pieces, which gives the pillow the bouncy responsiveness of natural latex with the adjustability of an open chamber, so you can tune the loft and firmness to your sleep position.
How does a natural latex pillow compare to memory foam?
Natural latex and memory foam both conform to your head, but they differ in heat, responsiveness, and adjustability. Memory foam traps heat because of its closed-cell structure. Dunlop latex pieces allow air to flow through their open cells, staying cool. Latex also bounces back faster, so your head doesn't get locked in a single impression. And because the Circadian latex pillow uses Dunlop pieces rather than a single block, you can adjust the loft, something solid memory foam can't offer.
Does a Talalay latex pillow have any scent?
A new Dunlop latex pillow has a faint rubber scent for the first three to seven nights. The scent comes from the natural tree-tapped sap and clears as the latex airs out. Unlike synthetic memory foam, there is no chemical off-gassing.
Can someone with a latex allergy use a natural latex pillow?
No. If you have a latex allergy, you should not use any latex pillow, whether natural or synthetic. The allergy is triggered by proteins in the latex itself, and these proteins are present in natural Dunlop latex. The organic cotton pillow, kapok pillow, or wool pillow would be safe alternatives.
What does OEKO-TEX certification mean for a latex pillow?
OEKO-TEX Standard 100 Class 1 certification means the latex fill has been independently tested for over 100 harmful substances, including carcinogenic dyes, pesticide residue, heavy metals, formaldehyde, and phthalates. Class 1 is the strictest tier of OEKO-TEX, the same standard used for products made for direct infant skin contact. Many latex pillows on the market are not third-party tested, so the certification provides verified safety rather than brand claims alone.
Is a Talalay latex pillow adjustable?
Yes. Dunlop latex pieces can be added or removed through a zipper, unlike solid latex blocks that come in a fixed size and firmness. The Circadian Tree-Tapped Latex pillow ships overstuffed so you can start full and remove pieces until the pillow matches your preferred height and softness.
Is a natural latex pillow good for hot sleepers?
Yes. Dunlop latex pieces are one of the better pillow options for hot sleepers because air circulates through the open-cell structure. The pillow runs cool through the night. Among the Circadian collection, it's cooler than cotton and comparable to wool, though not quite as cool as buckwheat.
How long does a Talalay latex pillow last?
Natural Dunlop latex is one of the most durable pillow fills available, lasting five to eight years with normal use. Latex resists compression and breakdown better than cotton, wool, or synthetic foam. The adjustable zipper design extends the useful life further because you can redistribute or add pieces if one area settles.
What is the best pillow to replace memory foam?
A Dunlop latex pillow with adjustable pieces is a natural option for people leaving memory foam. The open-cell Dunlop structure breathes, bounces back when you move, and does not off-gas VOCs. The adjustable loft lets you dial in your preferred height, something solid memory foam blocks can't do.
Can you sleep on a Talalay latex pillow on your side?
Yes. Side sleepers typically need more fill for a taller pillow that supports the head at shoulder height. Keep the Dunlop latex pieces relatively full for side sleeping. Latex's contouring works well for side sleepers because it cushions the ear and cheek while supporting the neck.
Where does the latex in the Circadian pillow come from?
The natural Dunlop latex is made from the sap of Hevea brasiliensis rubber trees grown on FSC-certified plantations in Sri Lanka. The sap is harvested by making small incisions in the bark, similar to how maple syrup is collected. The sap is then processed using the Dunlop method in a facility that meets OEKO-TEX Standard 100 Class 1. No petrochemicals are used in the production of natural latex.
