A certified-organic, waterproof mattress for families who want the shortest possible ingredient list under their baby.
If organic materials top your list, the Naturepedic Organic Cotton Classic is the gold standard: GOTS-organic cotton, no polyurethane foam, no added flame-retardant chemicals, no vinyl or PVC, and a food-grade waterproof surface that still wipes clean. It's firm on both sides (no soft side to second-guess) over a supportive innerspring, which is exactly the firm, flat surface the AAP recommends (healthychildren.org). Skip it if the premium price is out of reach, or if you specifically want a plusher toddler side, since this one stays firm throughout. For chemical-conscious parents, it's worth the splurge.
