Naturepedic Organic Breathable Ultra Baby Crib Mattress (2-Stage)

Important note on crib mattresses

A crib mattress is one of the biggest everyday-contact items in a nursery. Babies spend a lot of time on it, and it also gets exposed to spit-up, diapers, and frequent cleaning. In this category, I look for clear material disclosure, a firm sleep surface, and construction that doesn’t rely on added “performance” treatments to do the heavy lifting.

What I avoid in crib mattresses

I avoid vinyl or PVC mattress covers and polyurethane foam-based mattresses, since these materials are common and can contain plasticizers such as phthalates and added flame-retardant chemicals, which are often found in children’s mattresses. I’m also cautious with waterproofing or “repellent” finishes when the material system isn’t clearly explained, and I skip antimicrobial treatments marketed as a selling point. I prefer mattresses that rely on clearly disclosed materials and third-party standards rather than added chemical treatments for water resistance, odor control, or “germ protection.”

What I like

I appreciate that the brand is specific about what’s used for waterproofing and what’s included in the removable outer layer, rather than relying on vague or proprietary language. I also like that it’s a two-stage mattress, so it can be used from infancy through the toddler years.

Things to keep in mind

The airflow feature comes from the removable outer layer, which uses a 3D polyester structure along with other components to support washability and waterproofing.
