Not only is our mattress safe, but it’s also award-winning! It has been named the best crib mattress by top parenting publications and endorsed by pediatricians and sleep coaches nationwide.

Our innovative Breathe-Thru Technology allows your baby to breathe right through, reducing the risk of suffocation. They’ll rest easy. You can, too. Moreover, this is the only crib mattress that’s washable from cover to core. NO foam, glue, latex or springs, so your baby will enjoy a cleaner, hypoallergenic sleep.

With innovative breathe-thru technology, our baby + toddler mattress allows your baby to breathe right through. The patented, supportive core is encased in a soft, detachable cover with a waterproof lining on the toddler side. The proprietary core of our toddler mattress is made up of 90% air and 10% yogurt-cup material.

Newton Waterproof Crib Mattress FAQs

Do I need to add anything to my Newton mattress?

Your Newton mattress consists of the Wovenarie core material covered by a viscose encasement and the dual-layer removable outer cover with waterproof underlining on the toddler side. While your Newton mattress is the perfect sleep surface for your baby, you may consider adding some other items to create the ultimate sleep environment (and have backups in the linen closet).

Chances are you’ll want to purchase an Extra Cover. Fully removable, machine washable and interchangeable, our Extra Covers are lifesavers for parents who prefer to have one ready when late-night accidents occur.

Our Waterproof Mattress Pad is a safe, breathable option to traditional waterproof pads. It’s perfect for adding to your Newton once your little one can roll in both directions on their own (often sooner than you might think)! It’s easily the best item to have in your diaper bag as well — for caregivers or when traveling — as it can add a layer of breathability to any traditional sleeping surface.

Add sheets to your Newton from day one with our perfect-fit Organic Cotton Muslin sheets. They’re as breathable as our mattress, gentle to the touch, and get softer with more washes!
