The Allswell 10 inch Bed in a Box Hybrid Mattress
Lower concern for PFAS, but no transparency from brand on chemical treatments.
Allswell's hybrid mattress uses standard foam and fabric construction without confirmed PFAS-heavy components like water-resistant coatings or flame retardants. However, Allswell provides no public disclosure about PFAS in manufacturing or treatments.

The full breakdown
What it's made of and why it matters
The Allswell 10-inch hybrid uses polyurethane foam (core layer) combined with coil springs, wrapped in a cotton-polyester blend cover. Polyurethane foam can off-gas volatile organic compounds (VOCs) during the first 24-72 hours after unboxing, particularly formaldehyde and other solvents used in foam manufacture. The cotton-poly blend cover reduces risk compared to all-synthetic covers, though the polyester component may contribute minor VOC emissions. Hybrid construction with coils typically means lower overall foam density and mass than all-foam beds, potentially reducing cumulative off-gassing duration.
The brand's record and disclosure
Allswell (owned by Walmart) does not publicly disclose detailed chemical certifications, third-party testing results, or specific flame retardant formulations used in this mattress. The brand has not faced major safety recalls specific to this model as of available public records. No transparency statements regarding PFAS, formaldehyde limits, or other chemical safety standards are prominent on product pages or websites. This silence on chemical inputs makes independent verification of safety claims difficult, though absence of reported incidents does not confirm safety.
How it compares in its category
Budget hybrid mattresses like the Allswell 10-inch sit in the lower-certification tier compared to brands carrying CertiPUR-US (foam emissions), GOTS (organic fiber), or Oeko-Tex certifications. Most direct competitors at this price point (under $500 for queen) offer similar or identical polyurethane/coil construction without notable safety advantages. Higher-end hybrids often disclose flame retardant chemistry and off-gas testing; Allswell does not. For a "bed in a box" budget product, the material profile is standard but certification gaps are more pronounced than premium alternatives.
If you buy it
Unbox and air out the mattress in a well-ventilated room for 24-72 hours before sleeping, especially if you are sensitive to VOC odors; off-gassing typically decreases rapidly. Avoid direct heat sources (sunlight, heating pads) on the mattress surface, as polyurethane foam can degrade and off-gas more under sustained warmth. Use a mattress protector to minimize dust and microscopic foam particle exposure and to extend cover life. Expect typical lifespan of 5-7 years; replacement is warranted if visible sagging exceeds 1.5 inches or comfort noticeably declines.
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 compound (VOC) off-gassing from polyurethane foam
Standard polyurethane foam cores emit VOCs (formaldehyde, toluene, benzene precursors) during manufacturing residual release, especially in first 72 hours post-unboxing. Allswell does not publish CertiPUR-US or equivalent third-party off-gas testing, so emissions profile is unverified.
Flame retardant chemistry (undisclosed)
U.S. mattresses must meet flammability standards; chemical flame retardants used are not detailed by Allswell. Some budget mattresses use brominated or chlorinated compounds; without disclosure, residual chemical risk cannot be ruled out, though modern standards limit the worst options.
Polyester microfiber shedding from cover
Polyester-blend covers can shed fine fibers over time, particularly with friction or washing. Inhalation risk is low in normal use but increases with disturbance of aged or torn covers; cotton-poly blends shed less than 100% polyester alternatives.
Formaldehyde-based binders or adhesives in foam or cover assembly
Foam bonding and cover stitching may involve formaldehyde-containing adhesives or resins; Allswell provides no specification sheets or limits. Off-gassing typically subsides within weeks but is not lab-tested for this model.
Coil rust or leachates if cover is compromised
No widespread reports of premature rust in Allswell hybrid coils. Risk is minimal if cover remains intact; if torn, minor surface rust is cosmetic and does not leach into foam under normal indoor humidity.
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.
