Casper · Stain-Resistant Bed Sheets
Casper Percale Sheet Set
Lower concern, plain cotton sheets unlikely to contain PFAS, but Casper has made no public disclosure.
Casper Percale Sheet Sets are 100% cotton with no reported chemical finishes, coatings, or water-repellent treatments that would typically introduce PFAS. Cotton textiles in everyday use carry lower PFAS risk than treated performance fabrics or stain-resistant furnishings.

The full breakdown
What it's made of and why it matters
Casper Percale is 100% cotton in a tight percale weave, which means the fibers are twisted and tightly interlaced before being woven. This construction creates a crisp, cool-to-touch fabric without requiring synthetic coatings or chemical finishes to achieve performance. Cotton is a natural fiber with minimal inherent chemical hazards when grown and processed under standard textile industry controls, though the dye and finishing chemicals applied during manufacturing are the primary exposure route.
The brand's record and disclosure
Casper does not publicly disclose PFAS testing results or commitments to PFAS-free manufacturing, which is notable because many premium bedding brands have begun offering such transparency in response to consumer demand. The brand has not faced major product safety recalls or regulatory actions on record for bed sheets. Casper does not list third-party certifications such as OEKO-TEX, GOTS (Global Organic Textile Standard), or similar programs that would independently verify chemical safety in their standard product line.
How it compares in its category
Casper Percale sits in the mid-to-premium price tier for cotton percale sheets. Many competitors at similar price points (Brooklinen, Parachute, Helix) explicitly market OEKO-TEX or GOTS certification as a trust signal; Casper does not. Unbleached or certified organic percale alternatives carry lower chemical load from dyes and finishing agents, though Casper's conventional approach is standard across most mainstream bedding brands and carries no known acute hazard.
If you buy it
Wash in lukewarm water before first use to reduce loose dyes and sizing agents. Avoid chlorine bleach, which can degrade cotton fibers and interact unpredictably with any residual dyes; use oxygen-based alternatives if needed. Dry on medium heat or hang-dry to preserve the crisp percale finish. Replace when fabric pilling, thinning, or staining becomes visually prominent, typically 3-5 years with standard use and care.
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.”
Synthetic dyes and finishing residues
Standard cotton percale sheets are dyed and finished with chemicals (often including azo dyes and resin-based softeners) during manufacturing. Pre-wash removes most loose residue; no acute toxicity is documented for Casper sheets, but third-party certification (absent here) would confirm that dye metals and formaldehyde releasers are below safety thresholds.
Formaldehyde-releasing finishes
Percale's tight weave does not require wrinkle-resistant or sizing finishes that typically contain formaldehyde releasers. Casper's product specifications do not indicate use of these treatments, and no recalls or complaints on this hazard class are on record.
Heavy metals in dyes
Industrial dyes can carry trace cadmium, lead, or chromium depending on supplier and quality controls. Casper's supply chain transparency is not publicly detailed. OEKO-TEX certification would cap these metals; absence of certification means no independent verification, though standard industry practice keeps levels well below skin-contact exposure concerns.
Azo dyes and allergic sensitization
Azo dyes (especially in darker or dyed colors) can release aromatic amines under sweat or heat, a known contact allergen for sensitive skin. Pre-washing significantly reduces this risk. Casper does not specify azo-free dyes; fragrance-free, hypoallergenic alternatives with third-party certification exist at similar price points.
Microfiber shedding (pilling)
100% cotton percale does not shed microplastics. Standard cotton pilling is cosmetic and mechanical, not a chemical hazard. Quality percale (including Casper) resists pilling better than lower-thread-count weaves.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
