The Allswell Supreme Cooling Hybrid Mattress
Lower-concern mattress with no PFAS disclosures found, but no verification either.
The Allswell Supreme is a hybrid mattress combining foam and coils, materials not inherently PFAS-prone. No public evidence of flame-retardant coatings, stain treatments, or water-resistant finishes that would typically introduce 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 Allswell Supreme combines polyurethane foam layers with an innerspring coil system, typical of hybrid mattresses. The fabric cover is likely polyester-cotton blend with standard fire-barrier treatments. Foam and fabric off-gassing in the first weeks is normal for this category; the hybrid design (with coil ventilation) tends to disperse VOCs faster than all-foam models. No unusual material choices have been reported for this product.
The brand's record and disclosure
Allswell (owned by Walmart) provides basic CertiPUR-US foam certification, which screens for excessive heavy metals, ozone depleters, and phthalates in foam. The brand does not publicly disclose flame retardant chemistry or PFAS testing results, and no independent certifications (GOTS, OEKO-TEX) have been announced for this model. No recalls or safety violations are on record for Allswell mattresses.
How it compares in its category
Hybrid mattresses in the mid-range price tier typically use similar polyurethane foam and coil construction with chemical flame barriers. Allswell's CertiPUR-US backing is standard practice and meets basic safety thresholds. Higher-end competitors (like Helix or Leesa) often add GOTS-certified covers or OEKO-TEX labeling, but the Supreme does not claim these. For the budget-hybrid segment, material transparency is limited across the board.
If you buy it
Unbox and air the mattress in a well-ventilated room for 48 to 72 hours to minimize foam off-gassing odor; this is normal and not a safety signal. Use a removable, breathable mattress protector to extend life and reduce dust-mite accumulation. Rotate every 3 to 6 months to even wear. Avoid sustained heat exposure (electric blankets on high setting, direct sunlight) as polyurethane can degrade. Replace after 7 to 10 years or if sagging exceeds one inch.
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) off-gassing
Polyurethane foam and synthetic fabric covers routinely release VOCs in the first weeks after purchase. Allswell does not publish off-gas testing data; CertiPUR-US certification limits only a subset of VOCs. Adequate ventilation during break-in mitigates this.
Flame retardant chemical identity
Mattresses sold in the US must pass flammability standards; Allswell does not disclose whether this uses halogenated or non-halogenated retardants. Modern polyurethane formulations often avoid brominated compounds, but without transparency, exposure type cannot be confirmed.
Coil corrosion and rust particles
No reported issues with the Allswell Supreme's coil system. Standard steel springs are zinc or copper coated; degradation over time is cosmetic rather than a health risk in typical bedroom environments.
Polyester cover degradation and microfiber shedding
Polyester-blend covers can shed microfibers with washing or abrasion. Use of a removable protector reduces direct skin contact and fiber shedding into the sleep microenvironment.
Heavy metals in foam or adhesives
CertiPUR-US certification includes testing for cadmium, lead, and mercury in polyurethane foam. Allswell's CertiPUR-US badge indicates compliance with these limits; no independent reports of contamination exist for this brand.
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.
