The Allswell Supreme 14” Medium-Firm Mattress
Lower concern, but Allswell offers no transparency on PFAS, contact the brand directly if chemical disclosure matters to you.
The Allswell Supreme 14 uses standard polyurethane foam and polyester fabric, materials not typically flagged for PFAS in mattress applications. However, Allswell has not publicly disclosed PFAS policies or test results for this product.

The full breakdown
What it's made of and why it matters
The Allswell Supreme 14 uses polyurethane foam as its core comfort layer, wrapped in a polyester-blend fabric cover. Polyurethane foam is a common, well-established mattress material that typically off-gases volatile organic compounds (VOCs) in the first few days to weeks after purchase, though this dissipates significantly. The polyester cover may shed microfibers over time with normal use, though this is inherent to the material class rather than a brand-specific concern.
The brand's record and disclosure
Allswell (owned by Walmart) has not published detailed chemical composition disclosures or third-party certifications (such as CertiPUR-US or OEKO-TEX) in widely available public sources for this model. The brand has no documented product safety recalls related to the Supreme 14 mattress in FDA or CPSC databases. Allswell remains silent on PFAS use in their foam or cover treatments, which is typical of mainstream mattress manufacturers but limits transparency for consumers who prioritize chemical disclosure.
How it compares in its category
The Allswell Supreme 14 is positioned as a budget-friendly hybrid-style foam mattress; it lacks third-party certifications that distinguish premium brands (CertiPUR-US, GOTS, OEKO-TEX). Many competitors in the same price range offer similar polyurethane constructions without superior hazard profiles, though certified brands provide additional assurance of restricted chemical use. This mattress sits in the mass-market tier where chemical transparency is the exception rather than the norm.
If you buy it
Air out the mattress in a well-ventilated space for 24 to 72 hours after unboxing to allow initial VOC off-gassing to dissipate; this is normal and not a sign of defect. Use a mattress protector or pad to limit direct contact with the polyester cover and reduce microfiber exposure. Rotate or flip the mattress (if the design allows) every 3 to 6 months to extend lifespan and prevent uneven compression. Replace after 7 to 10 years or if comfort noticeably degrades, as polyurethane loses resilience over time.
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
New polyurethane mattresses commonly release low levels of VOCs during the first 1 to 3 weeks. No specific test data for the Allswell Supreme 14 is publicly available, but this off-gassing is typical of the material class and typically resolves quickly with ventilation.
Flame retardants in foam or cover
U.S. mattresses must meet federal flammability standards (16 CFR 1633), but Allswell does not publicly disclose which flame retardant chemicals are used in the Supreme 14. Chemical identity and concentration remain unknown; contact the brand directly if this is a concern.
Microfiber shedding from polyester cover
Polyester-blend covers shed microfibers during normal wear and washing. Shedding is inherent to the material but can be minimized with a mattress protector and gentle care.
Aluminum or other heavy metals in foam
No reports of heavy metal contamination in Allswell mattresses. Polyurethane foam does not typically leach metals, but chemical composition details are not publicly disclosed by the brand.
Bacterial or mold growth in foam
Polyurethane foam mattresses are not hygroscopic and resist moisture retention better than natural foams. No documented cases of biological contamination in the Allswell Supreme 14 line; standard mattress hygiene practices (mattress protector, occasional airing) mitigate this risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
