“So happy...now I have a spare when one is in the wash. These work great to stop accidents leaking to the core and are so easy to wash!”

Monique

“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.”

FAQ

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.
