Waterproof, Easy-To-Clean Surface will Save You a Lot of Aggravation

In a non-waterproof mattress, baby fluids such as urine, spit-up, and dribble can cause bacteria, mold and fungal growth, creating an unsafe sleeping environment for your baby. Vinyl/PVC, the covering of most inexpensive waterproof crib mattresses, is the most toxic plastic available and contain chemicals that can leach out or off-gas into the surrounding air.

This is the ultimate non-toxic water-proof and stain-resistant mattress surface! With this waterproof, dust mite proof mattress, there is no need to purchase additional items such as waterproof pads, wool moisture pads, or dust mite covers.

  • Protects from harmful fungi, mold, mildew and bacteria
  • Specially formulated waterproof surface – plant-based polyethylene made from non-GMO sugar cane
  • So pure that it meets food contact standards
  • No vinyl/PVC
  • Stain resistant
  • Super strong, tear resistant
  • Very easy to clean
  • Impenetrable barrier to dust mites/bed bugs and allergens – no need for additional cover
  • No Phthalates or Chemical Plasticizers – Independently Tested and Confirmed
  • NO Antimony, Arsenic or Phosphorus

Certified Organic, Safe and Non-Toxic – GOTS and GREENGUARD

Not only are the individual materials certified, but the finished mattress is certified as well. This ensures that all components meet a healthy non-toxic standard. Certified by OTCO to the Global Organic Textile Standard (GOTS). Also GREENGUARD SELECT Tested and Certified – the strictest standard. No harmful chemicals. No off-gassing.





No Wool and No Latex

A precautionary approach regarding allergies is reasonable for babies. It may be best to avoid baby mattress materials with allergenic properties like wool and latex until your child gets older and you know he or she won’t react.


No Fire Retardants or Barriers!

Made with Cotton – No Polyurethane Foam

Cotton does not burst into flames or release deadly fumes when ignited (as compared with polyurethane foam). This mattress passes all Federal and State flammability standards without the use of any fire retardant chemicals or FR barriers. It’s an innovative design using safe, non-toxic materials (organic cotton fabric, organic cotton fiber and food-grade polyethylene) and the elimination of polyurethane foam.

  • No PBDEs or any brominated or chlorinated fire retardants
  • No antimony, arsenic or phosphorus
  • No PAN (polyacrylonitrile), modacrylic, no dimethyl sulfate, and no boric acid, and no crystalline silica.
  • Confirmed by strict independent testing to not off-gas harmful substances.


Firm Support with Heavy Duty Orthopedic Innersprings

Naturepedic’s premium crib innerspring features 252 coils at 15.5 gauge, providing ideal support and weight distribution. It also has a 9 gauge border wire for strong edge support.

The 252 coil innerspring is a bit firmer and smoother, with better weight distribution than the 150. However, the real advantage lies in the center reinforcement. In addition to more coils, the 252 innerspring features 9 guage cross beams that help prevent sagging in the middle of the mattress. This is a concern with cribs that don’t support the center of the mattress well, i.e., a wire mesh crib bottom.


Environmentally Friendly Materials

Naturepedic mattresses are designed and constructed under the direction of a Board Certified Environmental Engineer (American Academy of Environmental Engineers), Qualified Environmental Professional (Institute of Professional Environmental Practice), and Certified Hazardous Materials Manager (Institute of Hazardous Materials Management).

Features U.S. grown and certified organic cotton filling. The food-grade polyethylene waterproof cover has a simple molecular structure that makes it unnecessary to use toxic chemicals in its production or add chemical plasticizers such as phthalates to make it soft. Typical waterproof covers and pads use vinyl/PVC, which releases dioxin into the environment during production and requires the use of phthalates that are harmful to both children and the environment. The polyurethane foam filling used in most mattresses is produced with numerous toxic chemicals. Switching from PVC/vinyl and polyurethane foam to organic cotton and polyethylene helps promote a healthier and safer environment.


Crib Mattress Pads, Sheets and Bedding

A 100% organic cotton pad and 100% organic cotton fitted sheet are recommended. The Naturepedic No- Compromise Organic Cotton Classic baby crib & toddler mattress is already waterproof; therefore no waterproof mattress pad is necessary. No dust mite cover is necessary – this mattress is already dust mite proof.

    I love this mattress and am so glad to know he is safe from the toxic chemicals from regular mattresses. I was terrified of SIDS and with this mattress I knew he was safe. This is by far the best item I have purchased for my little guy. The only flaw is that this mattress is on the larger side of ‘standard size’ and my crib seems to be on the smaller size of ‘standard size’. So it just means I have to work a little harder when it comes to changing sheets, but it is still well worth it! Oh, I did have to order sheets from Healthy Child because my regular crib sheets from Target were to small. I got the organic set of three and am also very happy with those. I have been using them about a year and a half and they are still holding up great even with all the washing they go through.

    Emily Smith:

    I was stressing about finding a mattress for my grandson’s new Dream On Me, Dream On Me Wonder Crib 3 in 1 electronic crib. I had been shopping for Organic mattress but some reviews were not favorable on various brands. I found Healthy Child on the internet and chose this mattress. My concern was, would it fit the crib? I called and talked to Valerie who assured me this mattress would fit the crib. Received it today and it fit perfectly! The mattress is firm but not hard and the cover adds additional comfort. It is safe from toxic chemicals and comfy to boot! My grandson is going to love sleeping in his new bed when he visits Grandma! Thank you Healthy Child for making this product available to us. The fact that it is made in the USA is very important to me. Looking forward to purchasing many more organic products from you.

    The Naturepedic No-Compromise Organic is a great mattress! I have used it for two years with my daughter and do not have a single complaint.

    If you are looking for a high quality, organic mattress, look no further than Naturepedic’s No Compromise Organic Cotton Mattress. Two years ago before our daughter’s birth, we were not sure whether spending double on an organic mattress was worth it, after much research we took the plunge and bought the Naturepedic mattress.

    Health concerns of traditional crib mattresses

    Nearly all mattresses on the market today contain chemical fire retardants, polyurethane foam, PVC and phthalates. Do a search for any one of those items and see the potential dangers associated with them. Health experts are slowly looking into the effects on a baby, I did not want to take any chances, especially when a baby spends 70% of the day sleeping.


    – Certified US grown organic cotton
    – Provides non-toxic fire protection and food grade waterproofing
    – Promotes baby health by eliminating harmful chemicals
    – Phthalates free (new study links this to ADHD)
    – Hypoallergenic / dust mite barrier cover
    – Made entirely in the USA

    My thoughts

    Two years later, we are still very happy with our decision and look forward to using it with our second baby who is coming in just a few months. For the quality and durability, the mattress still looks like it is brand new. As for the health concerns, it gives us peace of mind knowing that we do not need to be worried about what chemicals our daughter is being directly exposed to. If you are going to spend a lot of money on one item, spend it on the one thing where your baby will be spending most of their time.
