My Green Mattress Kiwi Organic Mattress – Certified Organic
Lower PFAS concern for a certified organic mattress, but brand is silent on chemical treatments and flame retardants.
My Green Mattress markets organic materials, which typically excludes PFAS-laden synthetics and Teflon-family coating coatings. However, the brand makes no explicit PFAS-free claim and does not disclose flame-retardant chemistry.
Material
Organic cotton, wool, natural latex
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
Why this grade
Category baseline
furniture is a category where PFAS exposure is more common.
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Kiwi uses certified organic cotton, wool, and natural latex as its primary layers. Organic cotton eliminates synthetic pesticide residues that conventional cotton can retain. Natural latex (rather than synthetic polyurethane foam) avoids off-gassing of isocyanates and other volatile chemicals common in petroleum-based foams. Wool provides inherent flame resistance without chemical treatment in many formulations, though the brand's specific approach is not publicly detailed.
The brand's record and disclosure
Organic Textiles holds third-party certifications (likely GOTS or similar organic standards) that audit pesticide and heavy-metal residues in fibers. However, the brand has not publicly disclosed its flame-retardant strategy, chemical finishing treatments, or adhesive compositions, which are common sources of concern in mattresses. No major recalls or safety controversies are on record for this product line. The silent stance on chemical treatments is a transparency gap rather than evidence of hazard.
How it compares in its category
Most conventional mattresses rely on polyurethane foam and synthetic cover fabrics treated with brominated or phosphorus-based flame retardants. This product's organic materials and natural latex represent a lower-chemical tier compared to budget and mid-range conventional options. It sits at a price and safety level comparable to other certified organic mattress brands (Avocado, Naturepedic, Helix Organic). The trade-off is that certifications cost more but reduce chemical exposure significantly.
If you buy it
Air out the mattress for 48-72 hours after unboxing to allow any residual odors from production or packaging to dissipate. Natural latex and wool are durable but sensitive to moisture; use a waterproof mattress protector and avoid saturating the surface. Spot-clean with mild soap and water only. Expect 8-10 years of typical use before foam density declines noticeably. Inspect seams and cover for tears annually to prevent latex oxidation.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Flame retardant chemicals (unlabeled)
Wool is naturally flame-resistant, but the brand does not publicly specify whether chemical flame retardants are applied to the cotton cover or internal layers. Organic standards do not prohibit all flame retardants, only synthetic ones; some approved natural or inorganic options may still be used without disclosure.
Formaldehyde in adhesives or finishes
Adhesives binding foam layers and glues in seaming can contain formaldehyde. Organic fiber certifications do not regulate internal adhesives. No specific disclosure from the brand on adhesive composition is publicly available.
Heavy metals in cotton or wool (pesticide residue)
Certified organic status audits for banned pesticides and heavy-metal contamination in raw fibers, significantly reducing risk compared to conventional cotton. No recalls or test failures are on record.
Latex protein allergies
Natural latex can trigger hypersensitivity in individuals with latex allergies. The brand does not label latex allergen risk or offer latex-free alternatives in this model.
VOC off-gassing (initial)
Even organic mattresses can emit volatile organic compounds from glues, dyes, or wool finishing in the first 1-2 weeks. Natural materials typically off-gas less than synthetic foams, but some odor and respiratory irritation during this period is not uncommon.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
