The Allswell Brick 12" Bed in a Box Hybrid Mattress
Lower concern for PFAS; typical bed-in-box with no red flags, but no transparency on chemical treatments.
The Allswell Brick mattress uses standard foam, springs, and textile construction with no disclosed PFAS-based treatments or coatings. Allswell provides no public statement on PFAS or flame-retardant chemistry.

The full breakdown
What it's made of and why it matters
The Allswell Brick 12 uses polyurethane foam as its core comfort layer, which is standard in this price segment. It combines this with steel coil springs for support and a polyester/cotton blend cover. Polyurethane foam is inherently flammable, so manufacturers must add flame retardant chemicals to meet federal fire standards (16 CFR 1633); this is true across nearly all US mattresses, not unique to Allswell. The cover blend is common and generally low-risk when new, though degradation over years can release microfibers.
The brand's record and disclosure
Allswell is owned by Walmart and positioned as a budget-friendly direct-to-consumer brand. The company has not published third-party certifications (CertiPUR-US, Oeko-Tex) or detailed chemical disclosure statements in publicly available materials, which is typical for brands at this price point but limits transparency. No established safety recalls or chemical controversies have been documented for this specific model. The brand's silence on PFAS and flame retardant chemistry reflects industry-wide opacity rather than a specific red flag.
How it compares in its category
The Brick 12 is competitively positioned in the budget bed-in-box market (sub-$500 range) alongside Casper, Nectar, and Zinus. Most direct-to-consumer mattresses at this price use identical polyurethane foam and spring construction with similar flame retardant requirements; differences lie mainly in cover materials and foam density. Allswell does not stand out as riskier or safer than peers. Mid-range and premium brands (Saatva, Helix, Avocado) often publish CertiPUR-US or organic certifications, which reduces guesswork about chemical composition.
If you buy it
Unbox and air the mattress in a well-ventilated room for 24-48 hours to off-gas volatile compounds; this is routine for all new foam mattresses and reduces odor and potential irritant exposure. Avoid direct heat sources and keep humidity moderate to slow foam and cover degradation. Rotate or flip the mattress every 3-6 months if the design allows (check the manual). Expected lifespan is 6-8 years; plan replacement when sagging exceeds 1 inch or foam becomes noticeably softer, as degraded foam poses no acute hazard but loses support.
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
New polyurethane mattresses typically emit low-to-moderate VOCs (mainly limonene, formaldehyde precursors, and isocyanate residues) for 24-72 hours. Allswell has not published off-gas testing data, so specific VOC profiles are unknown; initial off-gassing is expected and normal across the category but can trigger headaches or respiratory irritation in sensitive individuals.
Flame retardant chemical exposure (brominated or chlorinated compounds, antimony)
US federal flammability standard 16 CFR 1633 requires mattress foam to resist ignition; Allswell almost certainly uses flame retardant additives to meet this, though the specific chemistry is undisclosed. Exposure risk is low during normal sleep (chemicals are bound in foam), but increases with cover damage or foam deterioration over many years.
Polyester microfiber shedding from cover
The polyester/cotton blend cover can shed microfibers, especially if pilled or damaged. Inhalation risk is minimal during sleep on an intact cover, but becomes relevant if the cover tears or is extensively rubbed. No product-specific microfiber data is available.
Bacterial or mold growth if exposed to moisture
Polyurethane foam is hygroscopic and can trap moisture if the mattress is used in damp environments or subjected to spills. This creates conditions for mold or dust mite proliferation rather than chemical leaching, but sustained dampness degrades foam integrity and increases odor.
Lead or heavy metal contamination in dyes or cover treatment
No recalls or test data suggest heavy metal contamination in Allswell covers. Polyester and cotton fabric dyes are regulated under CPSIA, and no public incidents have flagged this brand. Risk is consistent with the broader bed-in-box category.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 68% 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.
