One feature found in some Naturepedic crib mattresses is the “waterproof” finish. These mattresses have a patented waterproof surface made without harmful chemicals for a hygienic design that is easy to clean. The waterproof surface is made of 100% food-grade polyethylene. (Note that the seams are not waterproof, unless you get the “seamless” feature - more on that below!)
“Ultra” is another option for the outer layer of Naturepedic crib mattresses. It’s described by Naturepedic as a “nicer finish”. This is also waterproof.
“Ultra Breathable” is another option. This is simply the “Ultra” mattress, as described above, plus a removable cotton mattress pad. The Ultra Breathable Mattress Pad features organic cotton fiber over a breathable layer of mesh and is designed to maximize airflow between the baby and the mattress. This breathable surface keeps the baby cool and dry for a more comfortable sleep with less risk of overheating.
“Quilted” is another finish available on the Naturepedic crib mattress. However, you will only this feature on their “2-stage” mattresses and the quilted finish will only be on the softer, toddler side. Quilted is your typical finish found on most mattresses and is not waterproof.
