Questions and answers

Is this mattress waterproof?
Yes. It has a waterproof medical-grade backing under the surface fabric, so spills do not soak into the foam. Wipe it clean rather than machine washing it.
Does it fit a standard crib?
Yes. It measures 52 by 27.5 inches, the standard crib and toddler bed size, and owners report a snug fit in most cribs.
Is it safe for a newborn?
It is a firm, flat, tight-top mattress with GREENGUARD Gold and CertiPUR-US certification, which is what infant sleep guidance calls for. Follow your crib maker's instructions on sheet fit.
How do I clean it?
Spot clean only. There is no removable cover, so use a damp cloth and mild soap and let it air dry fully.
Is $87.26 a good price?
That is the best new price found, at Wayfair as of November 8, 2026, and only two stores list it new. Certified foam crib mattresses often sell for more, so it is a low price for the category.
Does it work as a toddler bed mattress?
Yes. It is sized for both cribs and toddler beds, though the firm foam may feel hard to a heavier toddler.
