- Place your baby on their back, on a firm, flat crib mattress with only a fitted sheet.[1][2][3]
- The mattress must fit snugly: no gap wider than two fingers between the mattress and crib sides.[4]
- No pillows, bumpers, blankets, quilts or soft toys in the crib.[1][3]
- A full-size crib mattress should be no more than 6 inches thick.[5][6]
- Check recalls for your crib and mattress at CPSC.gov.[7]
Why Are Organic Baby Mattresses a Good Option?
Babies spend many hours a day sleeping, so parents want a mattress that is safe and well made. For safety, the most important features are firmness and fit, whatever the materials.[1][4] Organic crib mattresses use materials such as organic cotton, wool or natural latex. They can lower exposure to some chemicals, and certifications such as GOTS (for organic textiles) or GREENGUARD Gold (for low chemical emissions) show that the claims were checked by a third party.[8][9] There’s no evidence that an organic mattress lowers the risk of SIDS; safe sleep practices do.[10]Qualities of a Good Organic Baby Mattress
- Firm and flat: The AAP recommends a firm, flat sleep surface. A mattress is too soft if it indents when your baby lies on it.[1]
- Snug fit: Federal standards require full-size crib mattresses to fit the crib with no dangerous gaps.[5]
- Waterproof cover: A waterproof, wipeable surface helps keep the mattress clean.
- Certified claims: Look for GOTS for organic fabrics and GREENGUARD Gold for low emissions.[8][9]
- Fire safety: All mattresses must meet federal flammability rules; organic brands often use wool or other barriers instead of added chemical flame retardants.[11]
Features to Look For in an Organic Crib Mattress
Many crib mattresses are 2-stage: one firmer side for infants and a softer side for toddlers. Always use the firm infant side for babies under 12 months.[1] Lightweight mattresses make changing the sheets easier.What the Research Says
The AAP’s safe sleep recommendations focus on a firm, flat, level surface, a fitted sheet only, and nothing else in the crib.[1] CPSC rules require crib mattresses to fit the crib snugly and pass a firmness test, and all mattresses must meet federal flammability standards.[5][6][11] Organic certifications describe materials and emissions, not sleep safety, so check firmness and fit first.[8][9]How We Chose These Products
We don’t test products hands-on. We compared labels and listings: firmness, fit to standard full-size cribs, waterproofing, third-party certifications [8][9], and CPSC recall history [7]. We removed products that were out of stock, no longer listed or recalled, and we checked the brands we list against recent CPSC [7] recall notices in October 2026. None of the three mattresses below had a CPSC recall when we checked. We also removed three mattresses that are not organic (Newton Baby, Sealy Soybean and Graco Premium Foam), because this guide covers organic mattresses only. Brands don’t pay to be included, though we may earn a commission from purchases.Our Organic Baby Mattress Picks
