Top 3 Mini Crib Mattress Questions

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.

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.

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 snugly inside.
