Read the full description

Soft on your shoulders, level under your hips. Two inches of tree-tapped latex, wrapped in wool and sealed in a waterproof organic cotton case, on the mattress you already own.

The core is sap tapped from rubber trees in Sri Lanka, poured by the Dunlop method into a two-inch sheet of latex. A thin wrap of wool goes around it, and a knit organic cotton case closes over both. The latex is certified to OEKO-TEX Standard 100 at Class 1, the strictest tier, tested for formaldehyde, PFAS and more than 1,000 other harmful substances. The topper is made without chemical flame retardants.

It feels medium. Your shoulders and hips sink in a little while your waist and lower back stay held up, so you lie level. The wool takes the bounce off the surface, so the first thing you feel is soft.

Three inches thick. Handmade to order in New Jersey. Free shipping and a 60-night trial.

Sleep trial
You have 60 nights to sleep on it. Give it a few weeks before you judge it, because your body needs time to get used to a new feel. If it is still not right, write to jacob@circadianrest.com and we will make it right, with a full refund if that is what you want. To send it back, the topper needs to have been used under a mattress protector, and to come back clean and unstained, in its own case. We send you a return kit, a heavy bag to seal it in, with a prepaid label. Your refund goes out as soon as it reaches our workshop.

Quick answers

How firm is the topper?
It is medium. The two-inch latex core pushes back gently as you press in, so your shoulders and hips sink a little and your back stays level. The wool on top makes the first touch soft. On a firm mattress it adds give. On a soft mattress it adds a springy layer that holds its shape.
Will it make me sleep hot?
It runs cooler than a foam topper. Dunlop latex is poured with small holes that run through the sheet, so air moves through it as you turn. Foam is closed and dense, which is why foam toppers hold heat. The wool wrap between the latex and the case takes in damp and lets it go again, and your heat leaves with it, which keeps the temperature even.
Will it fix a mattress that sags?
No. A topper changes how the surface of your bed feels, so it softens a hard mattress well. It cannot lift a mattress that has a dip in the middle, because the topper follows the shape underneath it. If your mattress sags, the topper will sag with it.

More questions about this topper

As featured in

Tree-tapped latex, wrapped in wool

The sap is tapped from rubber trees in Sri Lanka and poured by the Dunlop method into a two-inch sheet of latex.

A thin wrap of wool goes around it, and a knit organic cotton case closes over both.

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

What's inside

  • Two inches of latex

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

  • A thin wrap of wool

    About half an inch of wool around the latex takes the bounce off the surface, so the first touch is soft.

  • Waterproof organic cotton case

    Organic cotton knit over a film made from corn starch. A spill stays on the surface.

  • Sap, not petroleum foam

    Many toppers are polyurethane foam, a plastic that sinks under you and holds your heat.

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

How it feels

Medium, with a little push back.

It suits side sleepers on a mattress that feels too hard, and back sleepers who want some give.

  • Sink

    Your shoulders and hips sink in.

    The wool on top is soft, and the latex under it gives a little.

  • Level

    Your back stays level.

    Latex pushes back as you press in, so you never sit in a dip.

  • Air

    Air moves through it.

    Dunlop latex is poured with small holes running through it.

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

I couldn't find a topper 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 the topper?

It is medium. The two-inch latex core pushes back gently as you press in, so your shoulders and hips sink a little and your back stays level. The wool on top makes the first touch soft. On a firm mattress it adds give. On a soft mattress it adds a springy layer that holds its shape.

Will it make me sleep hot?

It runs cooler than a foam topper. Dunlop latex is poured with small holes that run through the sheet, so air moves through it as you turn. Foam is closed and dense, which is why foam toppers hold heat. The wool wrap between the latex and the case takes in damp and lets it go again, and your heat leaves with it, which keeps the temperature even.

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 the topper is made without chemical flame retardants. The case fabric meets the GREENGUARD Gold standard for low chemical emissions. The latex is certified to OEKO-TEX Standard 100 at Class 1, tested for formaldehyde, PFAS and more than 1,000 other harmful substances.

Is there any PFAS in it?

No, there are no PFAS stain or water finishes on it. The case keeps spills out with a film thinner than paper, made from corn and bonded under the organic cotton knit, and that film is the one synthetic layer. Inside are latex tapped from rubber trees and a wrap of wool, with no polyurethane foam. The latex is certified to OEKO-TEX Standard 100 at Class 1, tested for PFAS and more than 1,000 other harmful substances.

Is the wool organic?

The organic part is the case, which is organic cotton knit. Inside it, a thin wrap of natural wool softens the feel of the latex and lets air move around it. The wool sits inside the case, wrapped around the latex, under the soft cotton knit you lie on. The latex is tapped from rubber trees and certified to OEKO-TEX Standard 100 at Class 1.

Is the case waterproof?

Yes. The case is organic cotton knit bonded to a thin waterproof film made from corn starch. A spill stays on the surface and never reaches the latex or wool. Blot it with a towel and let it air out. The soft cotton knit is the side you lie on.

Show 6 more questionsShow fewer questions
How do I care for it?

Spot clean the case with a damp cloth and a little mild soap, then let it dry fully before you make the bed. Never put the topper in a washer or dryer, because water would mat the wool. Once a month, air it out in the sun for a few hours. Sunlight and fresh air keep the wool dry and springy.

How long does delivery take?

Each topper 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 60 nights to sleep on it. Give it a few weeks before you judge it, because your body needs time to get used to a new feel. If it is still not right, write to jacob@circadianrest.com and we will make it right, with a full refund if that is what you want. To send it back, the topper needs to have been used under a mattress protector, and to come back clean and unstained, in its own case. We send you a return kit, a heavy bag to seal it in, with a prepaid label. Your refund goes out as soon as it reaches our workshop.

What's the warranty?

This topper has a 5-year limited warranty against manufacturing defects, such as a seam or the case failing under normal use. If it fails, we repair or replace it free. The thin wool wrap settles a little as it shapes to you, which is normal and not covered. Stains and a feel you don't like are not covered either. The 60-night trial is there for that. To make a claim, write to jacob@circadianrest.com with your order number and a photo.

Will my fitted sheet still fit?

Yes, if the pockets are deep enough. The topper adds three inches to the height of your bed. Measure your mattress, add three inches, and check that number against the pocket depth on your sheets.

Will it fix a mattress that sags?

No. A topper changes how the surface of your bed feels, so it softens a hard mattress well. It cannot lift a mattress that has a dip in the middle, because the topper follows the shape underneath it. If your mattress sags, the topper will sag with it.
