Your grandchild will spend up to 12 hours a day on their crib mattress — more time than on any other surface. What most people don't realize is that the majority of crib mattresses are made from polyurethane foam — the same material found in yoga mats and packing material. This foam releases volatile organic compounds (VOCs), invisible chemicals that off-gas directly into your grandchild's breathing zone.

Even mattresses marketed as "natural" or "organic" often use polyurethane foam as their core, hidden beneath a layer of organic cotton. KATU contains zero foam, zero polyurethane, and zero plastic — just organic latex, coconut fibre, wool, and cotton. Nothing to off-gas, nothing to worry about.

A study (source) found that many brands treat their crib mattresses with flame retardant chemicals to meet official standards. Unfortunately, these chemicals, such as polybrominated diphenyl ethers (PBDEs), have been linked to a range of health issues, including endocrine disruption, neurodevelopmental delays, and reproductive toxicity.

At KATU, we use organic wool as a natural flame retardant barrier, so no need for adding harmful chemicals.

A study by the National Center for Health Research (source) found that the Vinyl (PVC) commonly used in waterproof mattress covers often contains phthalates to increase flexibility. Phthalates are concerning as they're commonly linked to the onset of asthma and allergies.

As KATU, our mattresses are 100% vinyl/plastic-free, including organic materials only. We sell an organic cotton mattress protector separately for those interested.

KATU was started after the founders went through the stressful process of buying a crib mattress themselves, having to choose between unhealthy or expensive options. Something had to be done.

That's why we developed the KATU Organic 2-Stage Crib Mattress - comprised of just organic-certified latex, coconut fibre, wool and cotton. So grandparents and mothers can rest assured their little ones are sleeping safely - completely breathable, completely organic

For a limited period, as part of our mission to help as many parents and grandparents give their little ones safer sleep, we are offering $100 off all new mattress orders.

For those on the fence, KATU is also offering a 100-Night Risk-Free Trial where, if you don't like it by the end, we'll happily take the mattress back from you in return for a full refund. This is the cheapest price you will EVER find for a 100% organic crib mattress.

Not only that, we're also offering a Lifetime Guarantee with all mattresses as part of our Bed For Life™ program.
