Read the full description

Your shoulders and hips sink in a little and your back stays level, on a bed made from tree sap and wool. Six inches of tree-tapped latex, wrapped in wool and closed in a waterproof organic cotton case.

Most mattresses are built on polyurethane foam, a plastic made from petroleum, and you lie on it eight hours a night. This one is built on a six-inch block of latex made from the sap of rubber trees. The sap is tapped from living trees through a shallow cut in the bark, and the same tree keeps giving sap for decades. Ours comes from Sri Lanka, where rubber growing in Asia began in 1876.

Lie down and your shoulders and hips sink in a little. Your waist and the small of your back stay held up, so your spine lies level. Latex does this because it pushes back harder the further you press into it.

Handmade to order in New Jersey. Ships in 3 to 5 weeks, free, rolled in a box. Sleep on it for 120 nights, risk-free. After the first 30 nights, if it isn't right, you get a full refund with no fee.

Sleep trial
You have 120 nights to sleep on it. Give it at least 30 nights first, because your body needs a few weeks to get used to a new bed. If it is still not right after that, write to jacob@circadianrest.com and you get a full refund, with no fee. To send it back, the mattress needs to have been slept on with a mattress protector, and to come back clean and unstained, in its own case. We send you a return kit, a heavy mattress bag to seal it in, with the steps to book the pickup. Your refund goes out as soon as it reaches our workshop.

Quick answers

How firm is it?
It is medium-firm. The latex feels soft when you first lie down, then pushes back as your weight settles, so your shoulders and hips sink a little and your back stays level. Back and stomach sleepers usually like it as it comes. Side sleepers often add a two-inch topper for more cushion at the shoulder.
Is it good for side sleepers?
It can be, and a topper makes sure of it. On your side, your shoulder and hip carry most of your weight, so they need to sink further than they would on your back. The Organic Wool Mattress Topper gives them a soft place to go. The Tree-Tapped Latex Mattress Topper does the same with more spring.
Is there fiberglass in it?
No. Fiberglass is a common fire barrier in mattresses, sewn in as a sock under the cover, and it can shed if the cover is ever opened. This mattress meets the federal fire rule with wool. Wool is hard to set alight and chars in a flame instead of melting, so it protects the latex without any glass fiber or chemical flame retardant.

More questions about this mattress

As featured in

Made from tree sap and wool

The sap is tapped from living rubber trees through a shallow cut in the bark. It is poured slowly into a mold in small batches, so the block sets evenly and feels the same from top to bottom.

A layer of natural wool wraps the latex, and a knit organic cotton case closes over both.

Workers tap rubber trees on a plantation, white latex running from the cut bark into a cup.

What's inside

  • Tree-tapped latex

    Six inches of Dunlop latex, certified to OEKO-TEX Standard 100, Class 1, the tier used for baby products.

  • A wrap of natural wool

    Wool wraps the whole core. It is the fire barrier, so you sleep over wool instead of fiberglass.

  • Waterproof organic cotton case

    Organic cotton knit over a film made from corn starch, thinner than a sheet of paper. A spill stays on top.

  • Seven inches, rolled

    It ships rolled in a box, goes up the stairs easily, and opens out to full size on your frame.

What each layer does

You get the best of latex, wool and cotton, layered so each one sits where it does its job.

  • Latex holds you up

    It gives under your shoulder and pushes back under your hips, so your back stays level and the pressure comes off.

  • Wool keeps the temperature even

    It takes in damp and lets it go again, and your heat leaves with it, so the bed never turns warm and clammy.

  • Cotton is what you touch

    Soft organic cotton knit sits on top, sealed over a film made from corn, so a spill stays on the surface.

A worker slowly pours liquid latex into a pin mold beside a finished slab of Dunlop latex.

The longer version

Most mattresses are built on polyurethane foam, a plastic made from petroleum, and many pass the federal open-flame test with a sock of fiberglass or with flame retardant chemicals. This one is built on six inches of latex tapped from rubber trees and wrapped in wool, which passes that test on its own. The latex is certified to OEKO-TEX Standard 100 at Class 1, tested for more than 1,000 harmful substances, including formaldehyde, PFAS and heavy metals. The cotton in the case is the organic layer. The wool and the latex are natural, and we describe each one exactly as it is.

Jacob Katz, founder of Circadian, laughing on a bed.

I couldn't find a mattress I trusted either.

Jacob Katz, founder

I spend as much time outside as I can, and I wanted my eight hours in bed to be just as clean. Most mattresses are foam, with fiberglass or flame retardants to pass the fire test. Ours are made from tree-tapped latex, cotton and wool, with wool as the fire barrier. Every one is made by hand to order in New Jersey.

Common questions

How firm is it?

It is medium-firm. The latex feels soft when you first lie down, then pushes back as your weight settles, so your shoulders and hips sink a little and your back stays level. Back and stomach sleepers usually like it as it comes. Side sleepers often add a two-inch topper for more cushion at the shoulder.

Is it good for side sleepers?

It can be, and a topper makes sure of it. On your side, your shoulder and hip carry most of your weight, so they need to sink further than they would on your back. The Organic Wool Mattress Topper gives them a soft place to go. The Tree-Tapped Latex Mattress Topper does the same with more spring.

Will it off-gas?

It is built to keep off-gassing out of your bed. The core is latex tapped from rubber trees, with no polyurethane foam, and wool is the fire barrier, so there are no chemical flame retardants. The latex is certified to OEKO-TEX Standard 100 at Class 1, tested for formaldehyde, PFAS and more than 1,000 other harmful substances. The case fabric meets the GREENGUARD Gold standard for low chemical emissions.

Is there any PFAS in it?

No, there are no PFAS stain or water finishes on this mattress. PFAS, the forever chemicals, turn up in bedding sold as stain or water resistant, and this case keeps spills out without them. The only waterproofing is a film thinner than paper, made from corn and sealed under the organic cotton knit. That film is the one synthetic layer. Under it are wool and six inches of latex tapped from rubber trees, with no polyurethane foam.

Is there fiberglass in it?

No. Fiberglass is a common fire barrier in mattresses, sewn in as a sock under the cover, and it can shed if the cover is ever opened. This mattress meets the federal fire rule with wool. Wool is hard to set alight and chars in a flame instead of melting, so it protects the latex without any glass fiber or chemical flame retardant.

Is the latex organic?

The latex is natural. It is tapped from rubber trees and poured by the Dunlop method in small batches. It is certified to OEKO-TEX Standard 100 at Class 1, the strictest tier, the one used for baby products. The organic layer in this mattress is the cotton knit of the case. If you want organic cotton and organic wool through the whole bed, look at the Organic Wool & Tree-Tapped Latex Mattress.

Show 7 more questionsShow fewer questions
Will it make me sleep hot?

No, it stays cooler than a spring mattress with foam on top. The wool wrapped around the latex takes in damp and lets it go again, and your heat leaves with it. Dunlop latex is also poured with small holes running through it, so air moves as you turn. The case has a thin film to keep spills out. If you sleep very hot, the Organic Wool & Tree-Tapped Latex Mattress has no film, so only cotton sits between you and the wool.

Can I sleep on it with a latex allergy?

No. A diagnosed latex allergy rules out any latex mattress, ours included, because the proteins that cause it are part of natural rubber itself. For everyone else, the latex is certified to OEKO-TEX Standard 100 at Class 1 and sits inside a wool layer and a cotton case.

What do I put it on?

A platform bed, a solid foundation or a slatted frame all work. On slats, keep the gaps at about two to two and a half inches or less, so the latex is held evenly across the whole bed. No box spring is needed.

How does it arrive?

It comes rolled up in a box, which is much easier to get through a door and up the stairs than a flat mattress. A queen weighs about 80 pounds, so carry it in with two people. Unroll it on the frame, cut the plastic away and it opens out to full size. If an edge looks uneven after the trip, lift that end a few inches and let it drop, then smooth the top with your hands.

How long does delivery take?

Each mattress is made by hand to order in a New Jersey workshop. It ships in 3 to 5 weeks, and shipping is free. Transit is usually 2 to 5 business days after it leaves. We send tracking the day it ships.

What if it isn't right for me?

You have 120 nights to sleep on it. Give it at least 30 nights first, because your body needs a few weeks to get used to a new bed. If it is still not right after that, write to jacob@circadianrest.com and you get a full refund, with no fee. To send it back, the mattress needs to have been slept on with a mattress protector, and to come back clean and unstained, in its own case. We send you a return kit, a heavy mattress bag to seal it in, with the steps to book the pickup. Your refund goes out as soon as it reaches our workshop.

What's the warranty?

This mattress has a 20-year limited warranty. If it has a defect in the first 10 years, we repair or replace it and you pay nothing. In years 11 to 20 we still repair or replace it, and you pay part of the price you paid. Your share is 5 percent in year 11 and rises 5 percent a year, to 50 percent in year 20. It covers seams or the case failing under normal use, and a dip in the latex that you sink into, deeper than 1 inch when measured with nobody on the bed. The wool wrap settles a little as it shapes to you, which is normal and not covered, and turning it head to foot as the care card says keeps it even. Stains, a base that sags or has slats more than 3 inches apart, and a feel you don't like are not covered either. The 120-night trial is there for that. To make a claim, write to jacob@circadianrest.com with your order number and a photo.
