Stria Black and White Woven Silk Lumbar Pillow with Down-Alternative Insert 23''x11'' by Ackerman - CB2
Lower concern, natural silk cover and synthetic fill pose minimal inherent PFAS risk, but no transparency on treatments.
This pillow's primary materials (woven silk and down-alternative synthetic fibers) are not traditionally associated with PFAS. However, CB2 does not disclose whether the silk or polyester fill received water-repellent or stain-resistant finishing treatments, which could introduce PFAS.

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
This pillow pairs a woven silk cover with a polyester down-alternative fill. Silk is a protein fiber with minimal inherent chemical hazard and does not off-gas volatile compounds the way synthetic foams can. Polyester down-alternative fills (typically polyester fiberfill or microfiber) are chemically inert once cured and do not leach into skin contact. The combination avoids high-risk materials like memory foam (which can off-gas volatile organic compounds) or untreated feather fills (dust/mite concerns).
The brand's record and disclosure
CB2 is a home furnishings subsidiary of Crate and Barrel and maintains basic compliance with US Consumer Product Safety Commission standards. The brand does not publish detailed material safety certifications, third-party testing results, or chemical transparency reports for individual products. No recall history is on record for this specific pillow model. CB2 remains silent on PFAS treatment of textiles, which is consistent with industry-wide non-disclosure at the mass-market level.
How it compares in its category
Throw pillows with natural fiber covers (silk, cotton, linen) and synthetic fills are among the lower-risk options in the category. This is safer than pillows with polyurethane foam cores (VOC off-gassing risk) or covers treated with heavy water-repellent finishes (potential PFAS). However, it offers less third-party certification than premium brands that provide oeko-tex or bluesign testing. Price point and material pairing suggest this is mid-market with standard, not enhanced, chemical oversight.
If you buy it
Unpack and air out the pillow in a well-ventilated space for 24-48 hours before use, as new textiles may carry residual finishing odors. Silk covers require gentle care: hand-wash or dry-clean only; avoid high heat. Polyester fills are durable but inspect seams annually for wear; do not compress excessively in storage to avoid fiber breakdown. Replace if cover tears significantly or fill clumps after 3-5 years of regular use.
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-based finishing resins in silk or polyester
Woven silk and polyester blends may be treated with formaldehyde-releasing resins for wrinkle resistance or crease-setting during manufacturing. Most residual formaldehyde off-gases within days to weeks post-purchase; CB2 does not disclose resin type or levels.
Azo dyes in black weave
The black color in this pillow may use azo dyes, which can release aromatic amines under friction or moisture. Risk is low on a non-garment item with limited skin contact, but CB2 provides no dye safety documentation.
Microplastic shedding from polyester fill
Polyester fiberfill can shed microfibers over time, especially if seams degrade or the cover tears. This poses no direct toxicity but represents plastic waste. Regular inspection and repair extend functional life.
Flame retardants in fill or batting
No flame retardant treatment is required or typically applied to decorative pillow inserts in the US. Down-alternative polyester fills are not inherently flammable and do not require chemical additives for code compliance in this application.
Heavy metals in silk dyes
Silk dyes used for black woven fabric are not known to contain lead, cadmium, or arsenic at regulated levels in mainstream consumer textile products. CB2 does not disclose dye suppliers or heavy-metal testing.
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.
