Does it fit a standard crib?

Yes. At 52 by 28 inches it is sized for standard cribs and most toddler beds.

Is the cover waterproof?

Yes. The mattress has a waterproof barrier, and the removable cover is machine washable.

What does two-stage mean?

It has a firmer side for infants and a softer side for toddlers, so you flip it as the child grows.

Is it safe for indoor air?

It is GREENGUARD Gold certified and uses CertiPUR-US foam without toxic fire retardants.

Is $90.99 a good price?

It is the only new price found as of November 8, 2026, at Walmart, so there is little to compare it with. Certified two-stage foam mattresses often sell for more.

Does it need a separate mattress pad?

No. The cover is already waterproof, though a pad can make cleanup easier.
