Casper · Stain-Resistant Bed Sheets
Casper Hyperlite Set of 2 Shams
Lower concern, plain cotton pillowcases without water-resistant finish, but Casper makes no PFAS disclosure.
Casper Hyperlite Shams are 100% cotton sateen with no water-repellent or stain-resistant treatment listed, a lower-risk profile for PFAS. Casper does not publicly disclose PFAS sourcing, testing, or avoidance. No third-party certification or lab data is available to verify PFAS absence.

Why this grade

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
These shams are 100% cotton sateen, a tightly woven plain weave fabric with a subtle sheen from fiber alignment rather than chemical coating. Cotton sateen has no inherent toxicity concerns and does not require synthetic water-resistant finishes that would introduce PFAS or other water-repellent coating chemicals. The absence of a stain-resistant coating (despite the product category label) actually reduces exposure to potential hazardous finishes common in treated textiles.
The brand's record and disclosure
Casper does not publicly disclose PFAS use or avoidance in their bedding materials, which is typical of the sleep industry but falls short of transparency leaders like Patagonia or REI Co-op. The brand has no documented recalls, safety violations, or lawsuits specific to their sheet products. Casper has not pursued third-party certifications like OEKO-TEX or GOTS that would signal independent testing for harmful dyes, heavy metals, or chemical residues.
How it compares in its category
Cotton sateen shams sit at the middle-to-upper end of the bedding market for safety. Many budget brands use cotton-polyester blends with antimony catalysts in the polyester component and heavier chemical finishing; Casper's 100% cotton avoids this. Premium alternatives like Brooklinen and Parachute offer similar materials but with OEKO-TEX certification, providing third-party assurance on banned substances and restricted chemicals that Casper does not offer.
If you buy it
Wash before first use to remove any residual dyes, finishes, or manufacturing dust. Use warm water and mild detergent; hot water is unnecessary for cotton sateen and may accelerate wear. Dry on low heat or air-dry to preserve the sheen and avoid shrinkage. Replace every 2-3 years if pilling, thinning, or discoloration occurs; well-maintained cotton sateen typically outlasts synthetic alternatives.
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.”
Formaldehyde-releasing resins (wrinkle-resistant finishes)
Pure cotton sateen does not require formaldehyde-based wrinkle-resistance treatments if not marketed with that feature. No evidence Casper applies such finishes to this product; however, lack of disclosure means this cannot be fully ruled out.
Azo dyes and heavy metals in colorants
Cotton textiles may be dyed with azo dyes or contain heavy metal mordants (chromium, cobalt) used in coloring. Casper provides no testing data or dye standards; unbleached or white shams carry lower risk than deep colors.
Antimony in fiber or hardware
Antimony is primarily a concern in polyester, not cotton. This product is 100% cotton, so antimony contamination from the fiber itself is not a hazard; any metal hardware (if present) is not specified in available product information.
Residual manufacturing chemicals (finishes, lubricants, sizing)
Cotton sateen may retain spin oils, warp sizing, or finishing residues from the mill. Casper does not specify if fabrics undergo post-production washing or solvent treatment to remove these. Prewashing mitigates this concern.
Fragrance allergens or optical brighteners
No evidence Casper adds fragrance, perfume, or optical brighteners to these shams. These additives would be unusual in premium bedding but are not explicitly ruled out by brand disclosure.
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.
