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.
Slow-Pour 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 slow-pour Dunlop method: the latex is whipped to a froth, then poured slowly into the mold so air settles out between layers, giving a denser, more uniform foam than mass-market Dunlop. The block steam-cures into an open-cell foam, then we break it 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), and the rubber-tree source is FSC certified.
Adjustable Fill (Zipper Access)
The slow-pour Dunlop 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 slow-pour 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
Slow-pour 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.
Your head lands on something soft, and then the latex springs back and lifts it. That is the feel of Tree-Tapped Latex: plush at the surface, buoyant underneath, quick to respond when you move rather than holding the dent your head made an hour ago.
Air runs through the open pieces all night, so the surface stays cool with no gels or coatings. The cool comes from the structure of the fill, so it does not wear off.
It ships overstuffed, about 30% fuller than most people want. Open the side zipper and pull pieces out for a lower, softer profile, or work them back in when you want more height. One buyer took out about a third the first night and called the loft perfect for stomach sleeping. You set it, and you reset it any night your neck asks for something different.
It suits side, back, and combination sleepers, and it runs cool for people who sleep hot. If you want a surface that stays soft and support that stays springy, this is the one.
The latex is slow-pour Dunlop, whipped from 100% Hevea brasiliensis sap with no synthetic blend and made by hand in New Jersey. It carries OEKO-TEX Standard 100 at Class 1, the strictest tier in that program, tested to the same limits set for products made for babies. For processed latex that testing matters more than an organic label, because it checks the finished pillow for more than a hundred substances including formaldehyde, heavy metals, and phthalates. The rubber-tree source is Forest Stewardship Council (FSC) certified, and the organic cotton cover is sewn with undyed thread.
A faint natural rubber scent arrives in the first few days and airs out completely. If you have a latex allergy, the cotton, kapok, or wool pillow is the better pick.

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
Slow-pour Dunlop latex.
Slow-pour 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, then poured slowly into the mold so air settles out between layers, giving a denser, more uniform foam than mass-market Dunlop.
Under your head, slow-pour Dunlop 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. The slow pour is what separates the foam in this pillow from the mass-market Dunlop in cheaper latex pillows, which traps voids and runs uneven across the block.

Why it beats the memory foam you left
The reason memory foam let you down.
Memory foam feels great for a minute. Then your head presses a slow dent into it and settles there, and the foam wraps close and traps your heat with nowhere to go. By the middle of the night you are lying in a warm hole you have to climb out of every time you turn.
There is a quieter problem too. Memory foam is polyurethane, a petroleum foam, and it off-gasses volatile compounds into the air six inches from your face. The smell fades; the chemistry is the point. Natural latex gives you the support without any of that.
Memory foam sinks and holds you in a dent
→
It wraps close and traps your heat
→
Petroleum foam off-gasses as you breathe
→
Hot, restless, chemical sleep
Natural latex answers all three, the same support without the trade.
Springs back, never sinks
Latex pushes back and supports instead of swallowing your head, so you turn freely instead of climbing out of a dent all night.
Open cells breathe
Pin-holes and the gaps between the shredded pieces move air through all night, so heat never pools the way it does in dense foam.
Tested to infant-grade
OEKO-TEX Standard 100, Class 1 screens the finished latex for 100-plus compounds, the tier used for baby products, so there is nothing to off-gas.
Responsive support that breathes and stays clean means you get the cradle of foam without the heat, the sinking, or the chemistry. Tapped from a rubber tree, not poured from a barrel of oil.
A pillow you can adjust to fit you.
Most pillows come at one fixed height, so you sleep at a loft that was never set for your body, and your neck and shoulders pay for it in the morning. Every Circadian pillow ships overstuffed instead. You dial the height in on night one, fine-tune it over the trial, and the pillow you've shaped is yours to keep.

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 you're not sleeping on
The list most pillow makers hope you never read. None of it is in a Circadian pillow.
Certified. Verifiable. Public.
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 slow-pour Dunlop, tapped from Hevea brasiliensis rubber trees the way maple syrup is tapped. The sap is whipped, then poured slowly into the mold so air settles out between layers, giving a denser, more uniform foam than mass-market Dunlop. The block bakes 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, Class 1 means the finished latex has been tested for over 100 harmful compounds, the same standard applied to products made for direct infant skin contact. The cover is organic cotton.
Frequently asked questions
What is the difference between mass-market Dunlop and slow-pour Dunlop latex?
Dunlop latex is whipped, poured into a mold, and steam-cured into a dense, springy, open-cell material. Mass-market Dunlop pours fast, which traps air voids and leaves the block uneven. Our Tree-Tapped Latex Pillow uses slow-pour Dunlop, where the sap is poured slowly so the air settles out between layers, giving a denser, more uniform foam that holds up for years. We shred that cured block into pieces, so the pillow keeps the bouncy responsiveness of natural latex with the adjustability of an open chamber.
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. Slow-pour 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 slow-pour Dunlop pieces rather than a single block, you can adjust the loft, something solid memory foam can't offer.
Does a natural latex pillow have any scent?
A new slow-pour 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 natural latex pillow adjustable?
Yes. Slow-pour 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. Slow-pour Dunlop latex pieces are one of the better pillow options for hot sleepers because air circulates through the open-cell structure between the pieces. 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 natural latex pillow last?
Slow-pour Dunlop natural 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 slow-pour Dunlop latex pillow with adjustable pieces is a natural option for people leaving memory foam. The open-cell slow-pour 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 natural 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 slow-pour 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 slow-pour 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 slow-pour Dunlop method, and the finished latex is certified OEKO-TEX Standard 100, Class 1. No petrochemicals are used in the production of natural latex.
