Find your fit

Choose your comfort level

Two heights, two feels — built on the same clean cotton, wool, and latex. Pick the support that fits how you sleep.

Honest construction, layer by layer

Inside the mattress

Honest construction, layer by layer

Built only from materials we'd want against our own skin.

Layer 1: Quilted organic wool

A breathable, temperature-regulating cover. No fiberglass, or rayon poly-blends.

Layer 2: Organic latex

Responsive comfort and pressure relief, without the sink of synthetic foam.

Layer 3: Pocketed coil Support System

Recycled-steel springs, individually wrapped for motion isolation and adaptive support.

Organic cotton, the layer your skin touches

Ingredient 1

Organic cotton, the layer your skin touches

100% organic cotton at the sleep surface. No synthetic blends, no moisture-management sprays, no performance-fabric chemistry.

Organic wool, the natural thermostat

Ingredient 2

Organic wool, the natural thermostat

Cools in summer, warms in winter. It absorbs up to 30% of its weight in moisture while staying dry to the touch, and it meets the federal flame standard on its own.

Organic latex, the layer that contours to you

Ingredient 3

Organic latex, the layer that contours to you

Organic latex gives full-body contouring and pressure-point relief — cradling hips and shoulders without the dead sink of memory foam.

Pocket coils, the core that holds you up

Ingredient 4

Pocket coils, the core that holds you up

Individually wrapped coils are the support core: responsive lift that keeps your spine aligned, airflow through the whole bed, and motion isolation so you don't feel your partner move.

Clean enough to breathe on. Cool enough to sleep through.

Clean enough to breathe on. Cool enough to sleep through.

Most beds make you choose: an organic one that costs a fortune, or one made with materials that off-gas and leave you sleeping hot. This is the one that does neither.

What You're Sleeping On Now

Other mattresses sleep hot and emit harmful chemicals for your breathing.

Three problems are built into nearly every bed, and your body heat makes all three worse.

OFF-GASSING CHEMICALS

Polyurethane foam releases VOCs and phthalates for the life of the bed, and body heat drives them higher.

TRAPPED HEAT

Memory foam contours because it's dense, and this same density traps heat against you instead of letting it escape.

SPRAYED-ON FLAME RETARDANTS

Foam can't pass the federal flame standard alone, so it's treated with chemical flame retardants linked to health concerns.

TRANSPARENCY MATTERS

Beware of misleading mattress claims

Many mattresses are advertised as "made with organic cotton, wool, or latex," but that wording often hides the truth. If a product doesn't clearly state 100% organic, it usually contains synthetic blends. It's most common with latex, and with cotton and wool blends that mix in synthetics to cut cost.

At Cotton Sleep, we use 100% organic cotton, 100% organic wool, and 100% organic latex, grown and processed without harmful pesticides or synthetic chemicals.

Real reviews from people

Closed the thermostat war.

My wife sleeps hot, I care about clean materials. The only mattress that made both of us happy. The wool layer actually does what they say.

Hot sleeper, problem solved.

I used to flip the pillow and throw the covers off every night. First week on this bed, that just… stopped. I sleep through now.

No off-gassing, finally.

Unrolled it and there was nothing, just a faint natural-latex scent gone in a day. After two foam mattresses I had to throw out, that alone sold me.

Better than the $3,000 brand.

We had a big-name organic mattress before. This is the same materials, slept just as cool, and cost less than half. Wish we'd found it first.

Clean ingredients, clean conscience.

I can read every material on this bed and know exactly what I'm breathing. That peace of mind is the whole reason we bought it.

Real materials, real difference.

Organic cotton, wool, latex. Exactly what they say, nothing they don't. The room never smelled like a new mattress. Easy decision to keep it.

Your questions answered

Why a mattress like this when Amazon has one for $199?

Cotton Sleep

That $199 bed is polyurethane foam off-gassing in your bedroom. This is organic cotton, New Zealand wool, and natural latex, the same build as $1,500 mattresses. You're paying for what you breathe and sleep on, not the brand name.

Which firmness should I pick?

Cotton Sleep

Most side sleepers do best with Medium. Back and stomach sleepers usually want Medium-Firm or Firm. Couples with mismatched preferences should aim for the average. The latex contours while the pocket coils support, so the bed gives without sinking and the gap matters less than it does with foam.

Will it sleep hot like memory foam?

Cotton Sleep

The opposite. A moisture-wicking wool layer and open pocket coils move heat and air away instead of trapping it. This bed is built specifically for hot sleepers.

Will it off-gas when I unbox it?

Cotton Sleep

You'll notice a faint natural-latex smell like a new pair of leather shoes. It's not chemical, and it clears within 48 hours. There's no polyurethane, no flame retardants, and no VOC source to off-gas.

Are you organic?

Cotton Sleep

Our cotton, our wool and our latex are 100% organic at the material level.

The first few nights feel firm. Is that normal?

Cotton Sleep

Yes. Your body adjusts to a new sleep surface over the first several nights. If you'd like to fine-tune the feel, a topper does it.

How is it shipped?

Cotton Sleep

Free in the US, compressed and rolled in a box. Unbox it, give it 24 hours to reach full loft, and you're sleeping.

What if it's wrong for me?

Cotton Sleep

Sleep on it for 100 nights. If it's not right, we arrange a comfort solution or simply refund your money.

How long does it last?

Cotton Sleep

10-year warranty. The pocket-coil core and natural latex don't break down like memory foam, so most owners replace because they want to, not because they have to.

Consciously made

Innovation and responsibility in the same bed for lower emissions, organic materials, and a lighter-footprint supply chain.

Low emissions, high standards

Natural latex certified low-emission, tested against recognized international standards for VOCs and restricted substances.

Organically grown

Organic cotton and wool grown without synthetic pesticides or fertilizers. Purer to sleep on, gentler on the soil it came from.

Low-carbon supply chain

Premium materials like New Zealand wool, moved by consolidated shipments and sea freight over air for lower emissions.
