Overview
Description
This mattress features 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 breathable and plush dual-layer quilted cloud cover that provides comfort and unzips for easy washing.
They use absolutely no polyurethane foam, adhesives, metal springs or glue so it’s non-toxic, hypoallergenic, 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—and can even pop right in the shower (or rinse off with a hose) for a good washing.
The 2-stage design allows for longevity through the toddler years.
