"Great quality! It feels soft and firm at the same time. The material is excellent. We have one for our 17-month-old and bought a second for the one on the way. I wouldn’t buy any other mattress."

  • FAQ

    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. 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 every wash!

    Can my baby breathe through this mattress?

    Newton crib mattresses were tested for air permeability, suffocation risk, and Co2 rebreathing factors in a third-party CPSC-accredited laboratory. During these tests, Newton crib mattresses showed 97% more airflow than the leading organic crib mattress, reducing the risk of suffocation.

Top 3 Crib Mattress Questions

Top 3 Crib Mattress Questions

  • Is your baby mattress organic?

    While the Newton Crib Mattress is not organic, it is a safer crib mattress for baby. Most "organic" baby crib mattresses feature only one organic component, such as cotton fabric or stuffing, but they aren't fully organic. Newton offers a mattress that is not only completely breathable to reduce suffocation risk but also offers the only washable crib mattress, making it the most hygienic sleep surface for your baby. Our products are GREENGUARD Gold certified, proving that Newton offers only safe products for your family.

  • Why a breathable mattress for baby?

    A breathable, washable crib mattress not only helps to reduce the risk of suffocation but also helps regulate the baby's body temperature (that's right, no more sweaty backs!) and reduces dust mites and allergens. This allows babies to sleep more comfortably and longer through the night.

  • What is the crib mattress size?

    Standard crib mattress sizes are regulated to meet a minimum sizing of 27 1/4" x 51 5/8" and not thicker than 6 inches. Standard crib sizes, while also regulated, can vary a bit based on construction. If a crib is labeled as a standard crib, Newton Crib Mattresses will fit nice and snuggly inside.
