Babies sleep upwards of 10 to 20 hours per day, and this time is significant for their development, which is why the mattresses that they sleep on matter.

Traditional mattresses are made with polyurethane foam (which comes from petroleum) and are often soaked or sprayed with toxic fire retardants, such as formaldehyde or benzene. Crib mattresses are often coated in vinyl, which is waterproof but contains chemical plasticizers that leach and can be inhaled.

Because babies under two years of age are particularly vulnerable to environmental toxins, reducing chemical exposure and prioritizing a mattress with natural ingredients is essential. While there are a lot of organic crib mattress brands on the market—from niche organic cotton crib mattress brands to affordable organic crib mattress lines from larger manufacturers—here are nine sustainable brands making the best nontoxic crib mattresses for your little ones.

While you’re on the hunt for the best crib mattress, don’t forget to get a nontoxic crib! (We’ve got also you covered for organic crib sheets for your new organic baby mattress, and organic baby clothes while you’re at it!) Need your own mattress upgrade? Head here for our guide to the best affordable eco-friendly mattresses.
