What's Inside
1. Washable / Breathable Infant Cover
Air channels are engineered into every water-resistant mattress cover and mattress core. Our mattress cover fabrics carry the OEKO-TEX® STANDARD 100 label. This certifies that every fabric component of this mattress, (i.e. every thread), has been tested for harmful substances and that the mattress cover is entirely safe.
2. Zipper - Facilitate Easy Zip-Off Cover
Your baby spends a large portion of the day in their crib. Kiwi Sleep mattress comes with a removeable and washable cover to ensure a clean mattress.
3. Health & Safety Barrier
Parents can rest assured after removing the easy Zip-Off Cover for cleaning, that the internal portions of the mattress remain safe to touch, even while the cover is not in place, thanks to this sealed barrier that is OEKO-TEX Standard 100 certified.
4. Fire Proof Flame Barrier
The mattress conforms to all government flammability standards without using any chemical flame retardants. The Fire Proof Flame Barrier is crafted from Rayon & Polyester, completely devoid of fiberglass, antimony, silica, graphite, and other chemicals.
5. Infant Side Cushion Elements
Made with a CertiPUR-US® certified ILD 65 foam, the firmest foam used in crib mattresses. This ensures that the cushion elements will not envelope the infant’s face should the baby turn over in the crib.
6. Springs
Each individual spring element is directly coupled with an individual cushion. As an individual spring is compressed, it helps distribute the high spot cranial pressures over a larger area of the infant's skull.
7. Toddler Side Cushion Elements
Made with a CertiPUR-US® certified ILD 35 foam, the medium-firm foam used on the toddler side, makes for a very comfortable sleeping surface. When coupled with an individual spring element, this allows for the proper alignment of the toddler spine which is critical for alignment, growth, and development.
8. Washable / Waterproof Toddler Cover
We’ve designed the toddler side mattress cover to be waterproof and hence impervious to toddler accidents. Our mattress cover fabrics carry the OEKO-TEX® STANDARD 100 label. This certifies that every fabric component of this mattress, (i.e. every thread), has been tested for harmful substances and that the mattress cover is entirely safe.

What Parents Are Saying About Kiwi Sleep
We originally started out with the lullaby earth mattress and it was awful! Our baby is such a light sleeper and tosses and turns all night. We say she’s a whale slapping her tail down all night and rolling from side to side. I couldn’t stand how noisy and crinkly all the mattresses were. I wanted the most comfortable and quietest crib mattress well still being 100% breathable and safe. I finally came across this one and though it is the most expensive baby mattress on the market (the lullaby earth with waterproof mattress protector is only $50 less…) it is far superior than all of them. It is waterproof, soft, cozy, comfortable and most importantly FDA approved, 100% breathable, my baby at 3 months could roll over on her stomach and push herself up so the firmness is just right without feeling like a brick. If you’re a first-time parent just know that the crib mattress matters especially when every second of sleep counts.
We realized a couple weeks in that our newborn was a difficult sleeper. He didn’t suffer from colic or any other related issue but anytime he was put down he screamed. Bedtime routines didn’t work, swaddling didn’t work, we did all the things, nothing kept him sleeping for longer than 2 hours at a time, unless it was on me. This went on for 5 months. NOT an exaggeration.
When it came time to transition him from the bassinet to a crib I did as much research as possible. I read ever review and test study I could get my hands on. I landed on Kiwi Sleep and I’m so glad I did. Our sons first night in his crib he pulled two 5 hour stretches back to back. With one wake up for a change and some nursing. We were stunned.
Kiwi Sleep completely won us over, everything from customer service to product quality has been top tier. From the bottom of my heart, thank you Kiwi Sleep for bringing this product into our lives.
Safety in Crib Mattress is a big deal for me and my daughter allowed me to research choices for our first grad son. I chose Kiwi Sleep for several reasons. 1. Made in the USA with a GreenGuard Certification 2. It's breathability 3. Potential to eliminate the possibility of plagiocephaly. Out of packaging it moved to form quickly and no weird smells. The safety value is worth the cost.
Bought this for my grandchild's new nursery. (Baby not here just yet). The cover is soft and the mattress is an excellent quality. It appears like it will be much more comfortable than the average crib mattress. My daughter tested the "breathability" of the mattress by pressing her face into the mattress for a minute. States she could breathe with no problems. This is very important to us since we recently had a SIDS death in the family while co-sleeping with a parent. Hopefully, this mattress will add a layer of protection for this child and give us peace of mind
One of our twin babies has a bit of a flat side on his head. It’s benign and when I read that this mattress can alleviate the pressure on baby’s preferred side, we decided to get it. It is pretty soft yet safe. No more getting up at weird hours to turn their head. Time will tell if his head shape will improve, but so far this mattress is making optimistic. We also greatly appreciate that the mattress cover is pretty thick and beige. It definitely will not stain easily.
