The 5 Nasty Truths About Your Baby's Crib Mattress...
This is what mainstream mattress brands don't want you knowing.
Many crib mattresses emit VOCs, which are chemicals that can off-gas from materials like foam padding. Infants, due to their developing respiratory systems and proximity to the mattress, can inhale these compounds during sleep. A study by The University of Texas at Austin found that crib mattresses release significant amounts of VOCs, potentially exposing infants to harmful chemicals (source).
To meet flammability standards, many crib mattresses are treated with flame retardant chemicals. 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 (source).
A study by the National Center for Health Research found that Vinyl (PVC) is commonly used in waterproof mattress covers and may contain phthalates to increase flexibility. Phthalates are chemicals of concern due to their potential health effects, commonly linked to asthma and allergies. The U.S. Consumer Product Safety Commission has taken steps to limit the use of certain phthalates in children's products (source).
The aforementioned study by the National Center for Health also found that over time, the polyurethane foam often used in crib mattresses breaks up into small dust-like particles that once inhaled can potentially cause asthma, skin irritations, or cancer.
Many crib mattress manufacturers fail to disclose the full list of materials and chemicals used in their products. This lack of transparency leaves parents unable to make informed decisions about potential health risks, especially when it comes to toxic additives like flame retardants, adhesives, or waterproofing treatments.
after realizing the truth, thousands of moms are switching to this safer organic crib mattress.
Every layer is GOTS- and GOLS-certified organic - from the outer cover to the inner core, no gimmicks, no hidden synthetics, just pure natural materials you can trust.
The natural organic wool and latex layers work together to regulate temperature and moisture, keeping your baby comfortable through every season and every sleep. Naturally hypoallergenic, the materials resist allergens, dust mites, and bacteria, providing a safe, chemical-free surface for your baby's sensitive skin.
The crib mattress has a firm side and a slightly softer side. For infants, use the firm side (organic coconut fibre) for optimal spinal development. Once the baby is approximately one year old, turn the mattress over for a more comfortable sleep surface (organic latex) as they grow older. Both sides are firm enough to be safe for an infant.
We're so confident that you and your little one will love the mattress, we're willing to give you a 100-night RISK-FREE TRIAL… We want as many children to be saved from sub-standard mattresses and we hope this zero-risk opportunity to improve your baby's health will help to do so.
Should your mattress ever be rendered functionally unusable for whatever reason, we'll repair or replace it. As a US-based organic brand, we prioritize solving problems quickly and keeping our customers pleased.

Customer Reviews
Great mattress perfect for both the crib or a toddler bed. I love that there are two sides so it can be flipped to the softer side when your child is ready for the toddler stage.
Great mattress! Made from safe organic
materials with no odors or chemicals. The dual-sided design is perfect-firm for newborns, softer for older babies. Breathable and comfortable, my baby sleeps soundly. High quality, and the cover is easy to wash.
Very comfortable, correct and high-quality mattress for my child. I am delighted and recommend.
I had Newton crib mattresses for our older daughters, which theyre still sleeping on as toddlers. It seems that Newton has been somewhat of a gold standard for safe, healthy crib mattresses, but so far I am liking this Katu mattress as much if not more for our new baby. She sleeps more soundly on it, without interruptions, and so far I can see that it really supports her sleep and therefore growth.
This mattress has several layers of GOTS-certified goodness - organic coconut fiber on the infant side, organic wool for padding and fire resistance, and organic latex on the toddler side, all tucked into an organic cotton cover. On the product description each material is listed with its country of origin for transparency.
The cover itself is a beautiful soft sage green which I love. Its easy to unzip and wash, and this crib mattress also came with a waterproof mattress protector.
This young company also offers a lifetime guarantee and 100-night trial, so its clear that they really stand behind their product.
Im so happy I found this crib mattress and I wouldnt hesitate to recommend it as being on par or better than Newton mattresses. I will definitely be on the lookout for more from this company!
Really nice product and very high quality. Daughter had previously purchased another like this at a hundred bucks more and she said this one is better. No plastics, organic with a lifetime guarantee while also coming in less expensive than similar mattresses.It comes super well wrapped (in a box and double wrapped) keeping the mattress pristine in shipping. The extra mattress protector is also extremely nice. GOT certified, really creative materials and it feels amazing. This one is for my DIL and she is very excited. Both girls are very cautious about plastics and other chemicals so this is a great find. Perfect for a gift and it is great they have a lifetime guarantee so it will be great for multiple kids.Very happy with this product.
