Simmons Deep Sleep Collection Mattress
Conventional mattress with no known PFAS treatments, but brand makes no public disclosure, lower concern than stain-treated bedding.
Simmons Deep Sleep Collection is a traditional foam and coil mattress without disclosed PFAS-containing coatings or treatments. No public claims about PFAS, no third-party certifications found. Standard mattress construction poses lower PFAS risk than water- or stain-resistant bedding, though lack of transparency limits confidence.

The full breakdown
What it's made of and why it matters
Simmons Deep Sleep uses polyurethane foam, woven fabric, and steel coil springs, the industry standard since the 1970s. Polyurethane foam does off-gas volatile organic compounds (VOCs) during the first weeks after purchase, but at levels below regulatory concern for most users. The steel coils are zinc-coated to prevent rust, and the fabric cover is typically a cotton-polyester blend; neither poses known acute hazards at normal bedroom temperatures.
The brand's record and disclosure
Simmons (now part of Serta Simmons Bedding) makes no public commitment to PFAS avoidance or third-party testing transparency. The brand carries Certipur-US certification on many models, which screens for formaldehyde, ozone depletion, flame retardants, and phthalates in foam but does not address PFAS. No major recalls or safety controversies are on record for the Deep Sleep line.
How it compares in its category
This is a mass-market innerspring-foam hybrid at a mid-range price point. It lacks eco-certifications (organic, Global Organic Textile Standard) that brands like Avocado or Naturepedic market, but also avoids premium markup. Compared to memory foam only or latex-only mattresses, it presents similar or lower off-gassing risk due to lower total polyurethane density.
If you buy it
Air out the mattress in a well-ventilated room for 48 hours after delivery to reduce initial VOC exposure. Encase it in a washable cover if you have chemical sensitivity. Rotate the mattress every 3 months to even wear and extend lifespan beyond the typical 7-10 years. Do not expose to direct heat (space heaters, sunlight for prolonged periods) as this can accelerate foam degradation.
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 (VOC) off-gassing
Polyurethane foam mattresses release VOCs (toluene, methylene diphenyl diisocyanate residues) in the first 1-4 weeks, especially in warm, poorly ventilated rooms. Intensity varies by foam quality; Certipur-US certification limits but does not eliminate this. Reported symptoms in sensitive individuals are mild (headache, odor annoyance) rather than systemic.
Formaldehyde in adhesives and fabric finishes
Certipur-US certification and standard industry practice exclude intentional formaldehyde use in foam. Fabric dyes and finishes on the cover may contain trace formaldehyde releasers, but no product-specific reports exist for Simmons Deep Sleep.
Flame retardant residues
US law requires mattress fire barriers (typically fiberglass or treated fabric layers), but Certipur-US certified foams exclude brominated and chlorinated flame retardants. Simmons Deep Sleep models carry this certification, indicating compliance with these restrictions.
Microplastic and fiber shedding
Polyester components in the cover and any synthetic batting can shed fibers over years of use, especially with surface abrasion or dry cleaning. This is not unique to Simmons and poses negligible inhalation risk during normal sleeping; concern is mainly environmental at end-of-life.
Metal leaching (zinc from coil coating)
Steel coils are zinc-coated for corrosion resistance and do not leach into the foam or fabric under normal use. Moisture and sweat exposure do not create conditions for significant zinc migration in a mattress context.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 65% 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.
