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.
