The Reviews Are In
We're providing peace of mind — for bedtime and beyond.
"We purchased the Newton crib mattress for our 3 month old after extensive research. She absolutely loves the mattress and sleeps comfortably during her naps and at night. The mattress is very well designed and so breathable that I never worry about her now that she can roll to her belly. I love everything about this product including the washable covers. The soft pink is perfectly delicate and adds just the right touch!"
"I started recommending this mattress the morning after my baby slept on it for the first time—it was the first time she slept thru the night on her own! Great quality, easy to clean, baby obviously loves it so I love it too!"
"This mattress is truly breathable. I love that it is easy to clean. Our reflux baby is finally sleeping well."
"Super happy with our purchase. I loved that we could wash the whole thing if needed, and our baby seemed to love it too. Seamless transition from a basinet to a crib."
"My little one sleeps so great on this mattress. I don’t need to worry if she sleeps face down, it’s a relief how breathable it is."
"We recently transitioned from a bassinet to mini crib. She has slept well on it! The peace of mind that she'll be safe if she rolls on her belly is huge."
"Waiting for the baby, but the first thing I did was put my face in it, and I can breathe really well! Totally breathable."
"Love Newton! This is our second mattress for the second baby. We have the full size crib mattress for our first (who is now 2.5, and still uses it) and have been really happy with it! LOVE that it’s fully washable. Worth every penny!"

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 crib mattress not only helps to reduce the risk of suffocation but also helps regulate 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 snugly inside.
