The Allswell Relax 14 inch Bed in a Box Hybrid Mattress
Lower PFAS concern; standard hybrid mattress with no known PFAS-adjacent features, but brand provides no transparency.
The Allswell Relax 14" is a conventional hybrid mattress (foam, springs, polyester) with no obvious PFAS-risk triggers like water resistance, stain treatment, or nonstick coatings. Allswell makes no PFAS disclosures and holds no third-party certifications.

The full breakdown
What it's made of and why it matters
The Allswell Relax 14 uses a polyester fabric cover over a foam core with innerspring support, a common hybrid design. Polyester covers can off-gas volatile organic compounds (VOCs) during the first few weeks, particularly if the mattress was stored warm. The foam core (typically polyurethane) is the main component where flame retardant treatments and VOC emissions concentrate; the innerspring element itself is chemically inert steel. No known lead, cadmium, or heavy metal coatings are present in standard hybrid mattress construction of this type.
The brand's record and disclosure
Allswell does not publish detailed chemical ingredient disclosures, third-party certifications (CertiPUR-US, Oeko-Tex, or similar), or flame retardant chemical identification on their product pages. The brand offers a 100-night trial and 10-year warranty, but provides minimal transparency about material sourcing or testing. No public recalls or chemical safety controversies have been documented for this model. The silence on PFAS and flame retardant chemistry is typical of mainstream budget mattress brands but limits consumer verification.
How it compares in its category
Hybrid mattresses at this price point ($300-500 range for queen) rarely carry third-party chemical certifications; the Allswell is standard in that regard. Some competitors (Helix, Casper, Purple) publish CertiPUR-US foam certification and flame retardant details; others do not. The Allswell's lack of published testing places it in the middle of industry transparency, neither leading nor lagging. VOC and flame retardant exposure from this mattress is expected to be comparable to other non-certified hybrids in the same price tier.
If you buy it
Unbox and air the mattress in a well-ventilated room or outdoors for 24-48 hours to allow polyester off-gassing; new mattress smell typically dissipates within 2-4 weeks. Avoid exposing the foam core to high heat (direct sunlight, heating pads above 104F) to prevent accelerated degradation and chemical release. Use a breathable, non-plastic mattress protector to reduce dust and mite accumulation. Rotate or flip every 3-6 months if applicable (check manual) to extend the 10-year lifespan and monitor for sagging, which signals foam breakdown.
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.”
VOC off-gassing from polyester cover and polyurethane foam
New hybrid mattresses commonly release volatile organic compounds, especially polyester fabric and polyurethane foam. Allswell does not publish VOC test results (e.g., GreenGuard or similar); off-gassing is typical but unquantified for this model.
Flame retardant chemical composition
US federal flammability standards require flame retardant treatment in mattress foams; Allswell does not disclose which chemicals are used (brominated, phosphate-based, etc.). The specific retardant type and concentration remain unknown from available product information.
Polyurethane foam core degradation and off-gassing over time
Polyurethane foam is known to break down gradually with heat and humidity exposure, potentially releasing isocyanates and other compounds. No accelerated aging data is published for this specific mattress; degradation timing depends on storage and use conditions.
Microbe and dust mite colonization if unmaintained
Polyurethane foam and polyester covers absorb moisture and dust, creating environments for dust mites and mold if ventilation or cleaning is neglected. This is a hygiene and allergen concern rather than chemical toxicity but is relevant to long-term mattress safety.
Latex or natural rubber allergen (if present in foam formulation)
Allswell does not specify if the foam core contains latex or latex-like proteins; synthetic polyurethane formulations typically do not, but ingredient transparency is absent. No documented latex contamination incidents for this brand are on record.
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.
