Read the full description

A soft place for your shoulders and hips that stays cool and dry all night. Two inches of organic wool in an organic cotton case, on the mattress you already own.

A mattress that feels too hard presses into the two places that carry your weight, the shoulder and the hip. This topper gives them two inches of wool to sink into. You lie down onto something plush and quiet, and the mattress underneath still keeps your back level.

Wool keeps you cool by drawing damp up out of the air under you and letting it go again, and your heat leaves with it. It holds up to 30% of its own weight in moisture before it feels wet, so it keeps you cool for the whole night.

Handmade to order in New Jersey. Ships in 3 to 5 weeks, free. Sleep on it for 60 nights, risk-free, and get a full refund if it isn't right.

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. It ships in 3 to 5 weeks, and shipping is free.

Quick answers

How soft is it?
It is soft. Your shoulder and hip sink into two inches of wool, and the mattress underneath still holds your back level. On a firm mattress it takes the hard edge off. If you want a topper with more bounce and push back, look at the Tree-Tapped Latex Mattress Topper.
Should I choose the wool or the latex topper?
Choose wool for softness and cool, dry sleep. It is plush, quiet and breathes freely, because its case has no waterproof film. Choose latex for a springy layer that pushes back and keeps its shape, with a waterproof case. Both add give to a mattress that feels too hard.
Will it fix a mattress that sags?
No. A topper changes how the top 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.

More questions about this topper

As featured in

Organic wool, start to finish

Three layers of organic wool, laid flat and closed in an organic cotton twill case. It is tufted by hand, so the layers stay where they were laid.

The wool comes from New Zealand, and it is washed with gentle soap and given no chemical finish.

What's inside

  • Three layers of organic wool

  • Organic cotton twill case

    Plain organic cotton with no waterproof film, so the wool keeps you cool right through it.

  • Tufted by hand

    The tufts hold the layers in place, so the wool stays even across the bed.

  • GOTS certified organic

    The finished topper is certified to GOTS, the Global Organic Textile Standard, the wool inside as well as the case.

What's not in the topper.

Most toppersThis topper
Polyurethane foam, a plastic made from petroleum.
Three layers of organic wool.
Foam that holds damp and heat against your back.
Wool takes damp away, and your heat leaves with it.

The longer version

Foam toppers hold damp and heat against your back, and many are polyurethane, a plastic made from petroleum. This topper is three layers of organic wool in an organic cotton twill case. The finished topper is GOTS certified organic, and the wool is washed with gentle soap and given no chemical finish, so formaldehyde and PFAS are not part of your bed.

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 soft is it?

It is soft. Your shoulder and hip sink into two inches of wool, and the mattress underneath still holds your back level. On a firm mattress it takes the hard edge off. If you want a topper with more bounce and push back, look at the Tree-Tapped Latex Mattress Topper.

Should I choose the wool or the latex topper?

Choose wool for softness and cool, dry sleep. It is plush, quiet and breathes freely, because its case has no waterproof film. Choose latex for a springy layer that pushes back and keeps its shape, with a waterproof case. Both add give to a mattress that feels too hard.

Will it make me sleep hot?

No, it should help you stay cooler. Wool takes damp out of the air under you and lets it go again, and your heat leaves with it. It holds up to 30% of its weight in moisture before it feels wet, so you stay cool because you stay dry. The case is organic cotton twill with no waterproof film, so the wool does that work right through it. Foam toppers hold damp and heat against your back instead.

Will it flatten?

The wool packs down a little in the first months as it shapes to you, and that is normal for wool. To bring back its spring, shake it out and lay it in the sun and fresh air for a few hours every month or so. Turning it head to foot when you change the sheets helps it wear evenly.

Is it good for allergies?

Wool is hypoallergenic, and it keeps the bed drier. That matters because dust mites, the most common cause of dust allergy, need damp air to live. The wool and cotton in this topper are organic, made without chemical finishes, so the topper adds no fumes to the air you breathe at night.

Is it organic?

Yes. The finished topper is GOTS certified organic, the Global Organic Textile Standard. That covers the organic wool inside and the organic cotton case, and the workshop is audited every year.

Show 6 more questionsShow fewer questions
Is there any PFAS or plastic in it?

No, the topper is plastic-free, with no PFAS stain or water finishes. It is three layers of organic wool in an organic cotton twill case, with no foam and no waterproof film. The finished topper is GOTS certified organic, and GOTS, the Global Organic Textile Standard, bans PFAS, the forever chemicals found in stain repellents, at every stage.

Will my fitted sheet still fit?

Yes, if the pockets are deep enough. The topper adds about two inches to the height of your bed. Measure your mattress, add two inches, and check that number against the pocket depth on your sheets. Lay the topper on the mattress and pull the fitted sheet over both to hold it in place.

Can I wash it?

No, because water and heat would mat the wool. Spot clean the case with a damp cloth and a little mild soap, then let it dry fully. To keep it clean, put a washable protector over the topper. Our Waterproof Organic Cotton Mattress Protector has a pocket deep enough for a mattress and topper together.

Will it fix a mattress that sags?

No. A topper changes how the top 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.

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. It ships in 3 to 5 weeks, and shipping is free.

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 wool settles a little as it shapes to you, which is normal and not covered, and airing it as the care card says keeps it springy. Stains and a feel you don't like are not covered. The 60-night trial is there for that. To make a claim, write to jacob@circadianrest.com with your order number and a photo.
