Leesa 10" Original Memory Foam Mattress
Lower PFAS concern, but Leesa provides no transparency on flame retardants or coatings.
The Leesa 10 uses standard memory foam and polyester, materials not inherently associated with PFAS. However, Leesa does not disclose whether flame retardant treatments or any water/stain-resistant coatings contain PFAS.

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 Leesa 10 uses polyurethane memory foam as its core, wrapped in a polyester cover. Memory foam is petroleum-derived and off-gases volatile organic compounds (VOCs) in the first weeks to months after purchase, though levels decline rapidly. The polyester cover may contain dyes, finishes, or antimicrobial treatments applied during manufacturing. Flame retardants are nearly always present in mattresses to meet US federal standards (16 CFR 1633), but Leesa does not publicly disclose which chemicals or methods they use.
The brand's record and disclosure
Leesa does not publish detailed material safety data, certifications (such as CertiPUR-US or GOTS), or flame retardant composition on their website or product labels based on publicly available information. The brand has no known major safety recalls or contamination incidents on record. Their silence on flame retardants and coating treatments is typical of mainstream mattress manufacturers but limits independent verification of hazard control.
How it compares in its category
The Leesa 10 is positioned in the mid-range memory foam segment. Competitors with higher transparency (such as Avocado, Helix, or certified CertiPUR-US brands) publish foam certifications and flame retardant methods. Budget brands rarely disclose this information either. The PFAS score of 75/100 suggests lower reliance on water-resistant coatings than some competitors, a modest advantage in that hazard class.
If you buy it
Unbox and air the mattress in a ventilated room for 24-72 hours to allow initial VOC off-gassing. Do not heat or expose to direct flame. Use a mattress protector to reduce dust mite exposure and prolong cover life. Rotate or flip every 3-6 months if the product allows it. Replace after 8-10 years or if sagging exceeds 1.5 inches, as foam breakdown may release additional particles.
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.”
Volatile organic compounds (VOCs) from polyurethane foam
Memory foam mattresses typically emit low to moderate levels of VOCs (especially formaldehyde, toluene) in the first weeks after opening. Leesa provides no off-gassing test data. Airing the mattress mitigates this.
Flame retardant chemistry (undisclosed)
US mattress regulations require flame barriers. Leesa does not publish which flame retardants or methods are used. Common options include brominated compounds, chlorinated compounds, or melamine resins; exposure risk is low for intact mattresses but increases if cover is damaged.
Polyester cover dyes and finishes
Polyester covers may be treated with disperse dyes, antimicrobial agents (e.g., triclosan), or water-repellent coatings. No specific Leesa cover testing is on public record. Risk is minimal in normal use; contact dermatitis is rare.
Microparticle shedding from degraded foam
Over 8-10 years, memory foam can break down and shed small particles, especially if the cover tears. This is a normal aging process, not unique to Leesa. Mattress protectors significantly reduce particle release.
Dust mite and mold colonization
Foam mattresses retain moisture and body warmth, creating favorable conditions for dust mites and mold if not rotated regularly or exposed to high humidity. Standard hygiene measures (protector, ventilation, rotation) minimize this.
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.
