Product details:

Every inch of this mattress was designed for your baby's health, safety and comfort. The star of the show: a patented Wovenaire core that's made of 90% free air (yes, air) and 10% food-grade polymer—so basically your baby could breathe right through it. It's all wrapped up in a soft, single layer eyelet cover with a natural viscose lining. Viscose is their natural chemical-free approach for exceeding rigorous federal flammability standards. They use absolutely no polyurethane foam, adhesives, metal springs or glue so it's non-toxic, hypoallergenic, recyclable and Greenguard Gold certified. A third-party CPSC accredited laboratory showed that a baby gets 97% more air while breathing through a Newton Crib Mattress than on a conventional waterproof crib mattress. The washable material prevents bacteria growth—you can pop right in the bath or shower (or rinse off with a hose) for a good washing for those inevitable messes. The 2-stage design allows for longevity through the toddler years. If you're comparing mattresses, the key differences are in the mattress thickness and whether the cover is single-layer or dual-layer.
