The Reviews Are In
We're providing peace of mind — for bedtime and beyond.
"The easy cleaning and handling method of the crib and the mattress cover made me get an extra one. Now whenever I need to wash the original cover, I just slip this extra one onto the mattress."
"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!"
"I have been a newton customer for over 3 years (with the SAME mattress!!). My old one has really held up. After 3 years of everyday use and multiple washes it's still nice and fits the mattress perfectly."
"I'm so glad I purchased this. Would definitely recommend buying an extra crib mattress cover, so you can actually clean the one the mattress came with. Perfect fit!"
"So thankful for an extra cover! We have a reflux baby so large spitup each night was unavoidable. Remove, was, replace, repeat!"
The Newton Crib Mattress Cover is made two layers of Breathe-Thru spacer fabric that is cozy enough for your little one and durable enough for everyday use. Simply throw the messy cover into the washing machine and replace with a fresh clean cover to get your baby (and you!) back to sleep more quickly.
- Standard Dimensions: 52" x 28" x 5.5"
- Tailored to fit snugly on the Wovenaire® core of your Original Crib Mattress.

Does this product come with a mattress?
The Newton crib mattresses come with the Wovenaire core and an outer cover. This is an extra cover for when the cover is soiled and needs to be laundered. It is interchangeable to the mattress type it is meant for use with.
Can I use this instead of a sheet?
While our covers are very soft, washable, and breathe-thru, most parents use a Newton Organic Cotton Sheet over the mattress cover.
