Affordable 100% Organic Crib Mattress Most Crib Mattresses are Plastic: We’re Changing That

Even many of the “organic” brands are selling plastic foam wrapped in organic cotton

Bed for Life
Should your mattress ever be rendered functionally unusable for whatever reason, we’ll repair it for you.

The Organic Mattress That’s Changing the Game
KATU’s mission is to make truly healthy sleeping accessible to all parents (and their babies!).
We (Hannah and Tom) are a couple that went through the pain of having to deal with the US crib mattress-buying process and immediately knew something had to change. We could choose affordable or healthy, but never both at once!
Knowing other parents in America must have been facing the same dilemma, we set off on a mission to make healthy crib mattresses accessible to all parents, not just the richest ones.
By focusing just on what parents actually care about (i.e. healthy, well-built, verifiably-tested product, for an affordable price) and after years of development, we produced the KATU Organic Crib Mattress.

GOLS – Global Organic Latex Standard
Our latex and coconut fibre (soaked in latex) is exclusively sourced from GOLS-certified suppliers, meaning they contain over 95% organic content and adhere to strict emissions standards

GOTS – Global Organic Textile Standard
Our cotton and wool is exclusively sourced from GOTS-certified suppliers, meaning they contain over 95% organic content. This requires rigorous testing of the supply chain from the farms to factories, also including social and environmental criteria
How does the dual-sided design benefit my child?
The crib mattress has a firm side for infants and a slightly softer side for toddlers. Flip it over when your baby turns one. Both sides are safe and firm enough for infants.
How do I care for the mattress?
To keep the mattress plastic-free, it’s not waterproof. That’s why we include our KATU Organic Mattress Protector for free, perfectly fitted for the mattress.
Is the mattress safe for sensitive babies?
Sensitive babies benefit most from our 100% organic, VOC-free mattress, avoiding risks associated with mainstream mattresses.
Will this mattress fit my crib?
The mattress fits standard US cribs snugly at 52″ x 28″ x 4″ and weighs about 15lbs.
How do I know this mattress is safe for my baby?
Our mattress meets rigorous CPSIA and ASTM testing standards in 2024. Reach out to us for testing certificates for your peace of mind.
FINALLY, A PLASTIC-FREE CRIB MATTRESS – Many mainstream crib mattresses are glorified plastic – research shows that many emit Volatile Organic Compounds that are harmful to babies. Our organic crib mattress is here to change that
THE PEACE OF MIND YOU’VE BEEN LOOKING FOR – All materials used in this crib mattress are sourced from leading organic-certified (GOLS and GOTS) suppliers around the world, you can rest assured that your baby is sleeping safely
FOR CUSTOMERS WHO VALUE QUALITY OVER QUANTITY – Not only are our non-toxic crib mattresses expertly crafted from the finest materials, the design is 2-sided (coconut fibre side for infants, latex side for toddlers) meaning you’ll get 4+ years of use out of this single crib mattress!
TRY WITHOUT RISK – We’re so confident in our artisan-handcrafted breathable crib mattresses that we offer a lifetime guarantee – rest assured you’ll never be buying a crib mattress again!

Soft, Supportive, and Truly Organic—So Glad I Took the Plunge
After trying another well-known organic crib mattress that felt too firm, I was on the hunt for something safer and more comfortable—especially since I often end up sleeping on it with my toddler. This KATU mattress has been exactly what we needed. It’s noticeably softer and more cushioned thanks to the natural latex and absence of springs. It fits perfectly in our crib and with our sheets. It has a nice thickness to it.There’s no chemical odor, which was a big concern for me, and the materials feel high-quality and thoughtfully made. I was hesitant to order since most reviews were from Vine voices, but I’m genuinely so happy I went for it. If you’re on the fence, don’t hesitate—this mattress has been a fantastic upgrade.

High-Quality Mattress That Gives Me Peace of Mind
After doing a lot of research, I decided to try the KATU Mattress, and I’m really happy with the decision.The mattress feels solid and well-made, with just the right level of firmness for my baby. It fits snugly in the crib without any gaps, which makes me feel confident about its safety. My baby seems comfortable on it and has been sleeping well since we started using it.One of the main reasons I chose this mattress is the use of organic materials. It’s reassuring to know my baby isn’t exposed to unnecessary chemicals while they sleep. There was no strong chemical smell when we unboxed it, unlike some other mattresses we’ve tried in the past.The only small downside is that it’s a bit pricier than some other options out there. That said, I think the quality and peace of mind make it worth the investment.Overall, I’d recommend the KATU Organic Crib Mattress to any parent looking for a safe, reliable, and eco-friendly option. It’s been a great addition to our nursery!

Solid Crib Mattress with Good Features
After a lot of research, we decided to go with this crib mattress, and overall, it’s been a great choice. The firmness is just right for safe sleep, and I appreciate that it’s made with organic materials. There was no strong odor when we first opened it, which was reassuring.The fit in our crib is snug, and it feels well-made. I also like that it’s dual-sided, so we can continue using it as our baby grows. That being said, it is a little firmer than I expected—some parents might prefer something slightly softer for a toddler.Price-wise, it’s not the cheapest option out there, but I think the quality justifies the cost. If you’re looking for an organic crib mattress with good safety features, this is definitely one to consider.

Where is the free mattress protector?
The mattress is great. Best I’ve tried with my 3rd baby. The Amazon experience has been a nightmare though. Will write a new review if I get a response from the seller on how great this mattress is.The first time I ordered it, it came folded in half inside the box with the firm infant side on the inside of the fold. It was ruined so I returned it. The second came in an appropriate box.Both times it did not come with the free mattress protector. If I get one, I would change my review to 5 stars but this mattress is expensive so I don’t want to spend an additional $50-100 on organic protector when it was said to be included.

Meh. Good enough to not return but I’m not over the moon
3-4 star… it feels organic. Soft and good quality. It’s heavy though. And its smell never fully lifted for us. I’d probably buy a washable one over this one if I could do it all over again.
Saiko –
Definitely worth the price.
We’ve been using this mattress for about five months and really love it. The natural materials give us peace of mind, and our baby sleeps great on it. It’s a bit heavy and thinner than regular mattresses, but we like how it feels and hope it lasts a long time.

Excellent mattress!
This KATU crib mattress is truly top-tier. The quality is exceptional—it feels sturdy yet comfortable, and the dual-sided design is perfect for transitioning from infant to toddler. 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. It’s breathable, hypoallergenic, and fits perfectly in the crib. If you’re looking for a healthy, durable mattress that supports your baby’s development, this is a fantastic choice.

GOL certified. Wool, coconut, latex. I love it all!
This is a step up from my first eco latex crib mattress. First and most importantly, it’s GOLS certified. That means it was grown without pesticides, harvested and processed in a neutral/sustainable way and is the lowest likely to off gas anything at all. The mattress is mostly a coconut coir pad (75%), with natural rubber latex (at 25%). There is still a high amount of structure on both sides, exactly as a crib should have. It’s comfortable.The mattress is also wrapped on the interior with 100% organic wool (for natural fire protection), then covered with a 100% organic cotton cover all around. This is a ton nicer than my previous one. My older, similarly priced one was covered in a much lesser quality cotton, no wool, no certification, no coconut (springs instead). The bed I sleep in (also latex) has this same organic material for the cover. The manufacturer took great care in using quality materials.I haven’t had any complaints whatsoever with this. I’m tickled by the quality of this mattress. It does sound like if there’s any problem at all, that the manufacturer stands behind their product and welcomes all inquires for help.
