The most transparent name in baby sleep.
Baby sleep is all we do. Certified organic mattresses and bedding, traced from farm to nursery.
Trusted by 10,000+ Moms
Two sides. Four layers. Nothing else.
One mattress that grows with your baby: a firm organic side for infants, a softer organic side for toddlers. Flip it at their first birthday and it lasts to age four and beyond.
Cover - GOTS Organic Cotton
A durable, breathable outer layer, soft against your baby's skin.
Comfort Layer - GOTS Organic Wool
Nature's own fire barrier. Regulates temperature and wicks moisture, with no chemical flame retardants needed.
Toddler Side (1-4+ yrs) - GOLS Organic Latex
Medium-density natural latex for comfort once safe, independent sleep is established.
Infant Side (0-12 mo) - GOLS Organic Coconut Fibre
High-density and firm, exactly the way infant sleep guidance says it should be.
Even the bond between layers is natural latex. No glues, no synthetics, no exceptions.
Certified, not claimed.
"Organic" and "non-toxic" are easy words to print. We back ours all the way down to the fiber.
Certified to the fiber
Every layer is GOTS or GOLS certified organic, audited annually by Control Union. The finished mattress is UL GREENGUARD Gold certified for low chemical emissions. License numbers CU 1416107 (GOTS) and CU 912089 (GOLS) - look us up on the public registry.
Handmade in Sri Lanka
Every mattress is cut, layered, and sewn by hand in small batches in Sri Lanka, minutes from the farms its latex and coir come from.
Tested by people we can't pay
Independent reviewers test our mattress on their own terms - we're proud to be Forbes Vetted, and we never pay for praise.
Unbeatable benefits, unbeatable price.

"I was worried about that weird foam smell some mattresses have, but this had none. Fits the crib super tight with no gaps. Baby sleeps great."
"Knowing it's made from 100% organic latex and coconut, with GOTS and GOLS certifications, gives me peace of mind that it's non-toxic and safe for my baby."
"I learned about the Katu on Mommyhood101 and they had great things to say. With the competitive price, I gave it a shot. Baby safe, mom approved!"

Questions parents ask us.
Why is the infant side so firm?
A firm, flat surface is what safe-sleep guidance calls for in the first year. The coconut-fibre side is deliberately firm for infants; flip to the softer latex side around their first birthday.
Will it smell when it arrives?
Natural wool can carry a mild lanolin scent out of the box. It's harmless and fades fast - let the mattress air for a day and it's gone. What you won't get is the chemical off-gassing of foam mattresses.
Does it fit my crib?
It's made to the US standard crib and toddler bed size, so it fits any full-size crib sold in the US. Exact dimensions are on the product page.
How does the 100-night trial work?
Sleep on it for up to 100 nights from delivery. Not right for your baby? Contact us - we arrange the collection and the return is completely free.
Can I actually verify the certifications?
Yes, and we wish more people asked. Our GOTS and GOLS licenses are listed on the public certification registry, and every batch is covered by transaction certificates. Our GREENGUARD Gold certification is listed on UL's SPOT database.
When will it arrive?
In-stock orders leave our US warehouse within a business day. Exact delivery timing for your order is shown at checkout.
