Casper Element Mattress
Lower PFAS concern for standard foam mattress, though Casper provides no public PFAS disclosure.
The Element mattress uses conventional polyurethane foam and textile construction without known water-repellent or stain-resistance treatments that typically introduce PFAS. Casper has not publicly disclosed PFAS testing or made PFAS-free claims.

What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
VOC off-gassing from polyurethane foam
New polyurethane foam mattresses commonly emit VOCs (formaldehyde, benzene, toluene) for hours to weeks after unboxing. The Casper Element is not exceptional in this regard; severity depends on room ventilation and individual sensitivity. Off-gassing is typically mild and temporary but can cause headache or respiratory irritation in poorly ventilated spaces.
Flame retardants
US federal flammability standards require mattress covers to resist ignition; manufacturers typically meet this with physical barriers or chemical treatments. Casper does not disclose the flame retardant method used in the Element. Risk is low for normal use but unknown chemical composition remains a transparency gap.
Source: EPA ↗Dust mite and mold accumulation over time
Not a chemical hazard but a hygiene concern: any mattress can harbor dust mites and mold if exposed to moisture or not aired regularly. Use a waterproof protector and maintain dry storage conditions to minimize this biological risk.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Polyester cover degradation and fiber shedding
No documented safety risk specific to the Casper Element. Over many years of use, polyester-cotton blends may pill or shed fibers, but this does not create a chemical hazard. Washing or wiping the cover periodically prevents accumulation.
Formaldehyde / VOCs
Polyester-cotton covers and polyurethane foam are not typical sources of formaldehyde in finished mattresses under normal use. Casper provides no test data to confirm absence, but no recalls or complaints on record for this product class.

What it's made of and why it matters
The Casper Element uses a polyester-cotton blend cover over a polyurethane foam core. Polyurethane foam can off-gas volatile organic compounds (VOCs) in the first days to weeks after purchase, though this typically dissipates quickly in well-ventilated spaces. The polyester-cotton blend cover itself is not a known primary source of chemical leaching during normal use. No cadmium, lead, or other heavy metals are standard in this material class.
The brand's record and disclosure
Casper has no published PFAS transparency statement or third-party chemical disclosure for the Element mattress as of public record. The brand has not faced major product safety recalls or chemical controversies with wide documentation. Casper does not advertise certifications like GOTS (organic) or Oeko-Tex for the Element line, which limits independent verification of chemical inputs.
How it compares in its category
The Element is a budget-friendly foam mattress; it sits below Casper's premium lines and lacks the organic or certified-clean positioning of brands like Avocado or Helix Wedge. Most direct competitors (Tuft & Needle, Leesa, Purple) similarly use polyurethane cores and synthetic covers without extensive chemical disclosure. For the price tier, chemical safety documentation is generally sparse across the category.
If you buy it
Unbox and air out the mattress in a well-ventilated room for 24-72 hours to allow VOC off-gassing to subside. Use a washable mattress protector or barrier if chemical sensitivity is a concern. Avoid exposing the mattress to direct heat sources, prolonged sunlight, or moisture, as these can degrade the foam and cover. Replace the mattress every 7-10 years, as polyurethane foam naturally compresses and loses support over time.
