Babies sleep up to 16 hours a day, with their face inches from the mattress, so a crib mattress is one of the most important non-toxic purchases you’ll make. Conventional crib mattresses can off-gas VOCs and contain flame retardants and polyurethane foam. A certified non-toxic crib mattress avoids that. Here are the best.
| Brand | Type | Key certifications | Best for |
|---|---|---|---|
| Avocado | Organic | GOTS, GOLS, GREENGUARD Gold | Overall organic pick |
| Naturepedic | Organic | GOTS, GREENGUARD Gold, MADE SAFE | Waterproof organic |
| Newton | Breathable | GREENGUARD Gold | Breathability/washable |
| My Green Mattress | Organic | GOTS, GOLS, GREENGUARD Gold | Value organic |
What to Look For
Prioritize third-party certifications: GREENGUARD Gold (verifies low chemical emissions), GOTS (organic textiles), and GOLS (organic latex). Avoid vague “natural” claims with no certification. A waterproof but non-toxic surface is also worth it for the inevitable messes, look for food-grade or plant-based waterproofing rather than vinyl.
Our Top Picks
Avocado: Best Overall Organic
Avocado’s organic crib mattress carries the same trio of certifications as its adult mattresses. GOTS, GOLS, and GREENGUARD Gold, with organic cotton, wool, and latex and no polyurethane foam or flame-retardant chemicals.
Naturepedic: Best Waterproof Organic
A pediatric favorite, Naturepedic combines GOTS organic materials with a non-toxic, food-grade waterproof surface (no vinyl/PVC) and GREENGUARD Gold + MADE SAFE certification, ideal for easy cleanup without compromising safety.
Newton & My Green Mattress
Newton’s breathable, fully washable design is GREENGUARD Gold certified and popular with parents worried about airflow; My Green Mattress offers GOTS/GOLS/GREENGUARD Gold organic construction at a more accessible price.
Firmness Comes First
Before any eco claim, a crib mattress has to be firm. Safe-sleep guidance is clear that infants need a flat, firm surface, since a soft mattress raises the risk of suffocation. A quick check is the press test: push your hand into the center and it should spring back without leaving a dent. Many organic mattresses use a dual-sided design, firm for infants and slightly softer for toddlers, so one mattress safely covers both stages.
About Off-Gassing
That chemical smell from a new conventional mattress is off-gassing, the release of volatile compounds from polyurethane foam and adhesives. A certified organic crib mattress made from cotton, wool, and latex avoids most of it, and GREENGUARD Gold testing specifically screens for low emissions. If a new mattress has any scent at all, air it out in a well-ventilated room for a day or two before your baby sleeps on it.
What to Avoid
Skip vinyl or PVC waterproofing, which can contain phthalates, and look for a food-grade or plant-based waterproof layer instead. Be cautious with vague “natural” or “plant-based foam” claims that carry no third-party certification, since a small share of plant content does not make a foam non-toxic. And think twice about a used crib mattress, because firmness breaks down over time.
The Bottom Line
Avocado is our overall organic pick, Naturepedic wins if you want a non-toxic waterproof surface, and My Green Mattress is the best value, all certified rather than just “natural”-labeled.
