Both mattresses hold finished-product GOTS, the foundational organic certification. The question of additional certifications is about what other independent standards have tested the finished product.

OEKO-TEX® Standard 100 Class I is the strictest OEKO-TEX tier, designed for products used by babies and toddlers, and tests against thresholds for formaldehyde, phthalates, heavy metals, and pesticide residues. The Avocado Green Mattress is certified to Class I at the finished-product level. Per public records, the Silk & Snow Organic Mattress holds OEKO-TEX Standard 100 on its cover, not at the finished-product level.

MADE SAFE® screens against thousands of substances known or suspected to harm human health, aquatic life, and wildlife. EWG Verified® requires full ingredient transparency and screens against EWG's health-based criteria — including prohibitions on chemical flame retardants, fiberglass, PFAS, and PVC. GREENGUARD Gold certifies against indoor air quality emission limits. UL® Formaldehyde-Free independently verifies the absence of added formaldehyde. The Silk & Snow Organic Mattress does not list these certifications publicly.

Avocado screens for 679 PFAS substances at parts-per-billion sensitivity across core materials and waterproof protectors. No detectable amounts have been found. Full results are published publicly in our Help Center.

Avocado holds B Corp certification (since May 2020, score 113.9), 1% for the Planet membership, Climate Label Certification, an 88% landfill diversion rate (UL 2799 validated), FSC® certification across the latex and manufacturing supply chain, Responsible Wool Standard, Responsible Down Standard, OEKO-TEX® MADE IN GREEN, and Fairtrade certification. Avocado has published a 48% absolute reduction in Scope 1+2+3 emissions since 2021 and produces an annual Impact Report. Silk & Snow has not published comparable brand-level sustainability program credentials.

EWG Verified® is an independent standard from the Environmental Working Group that requires full public disclosure of ingredients and screens the finished mattress against EWG's health-based criteria — including prohibitions on chemical flame retardants, fiberglass, PFAS, and PVC. The Avocado Green Mattress is EWG Verified®; the Silk & Snow Organic is not. For a full explanation, see What EWG Verified Means on a Mattress.
