Our take on the Simmons BeautySleep Kids Extra Firm Crib and Toddler Mattress

A dual-stage foam crib and toddler mattress with an extra-firm newborn side and a slightly softer toddler side. The waterproof cover wipes clean and resists stains, and the foam uses recycled content. It is GREENGUARD Gold certified for low chemical emissions and made without harmful fire retardants. Parents rate it highly for firmness and easy cleanup; the main trade-off is that the cover is not removable for machine washing.
