West Elm Outdoor Knotted Border Pillow
Outdoor pillow with no disclosed PFAS or water-repellent coating treatment info.
West Elm does not publicly disclose PFAS use or water-repellent coating treatments for this pillow. Without lab testing or brand transparency, PFAS risk from water-resistant coatings cannot be ruled out on outdoor textiles.

The full breakdown
What it's made of and why it matters
West Elm's outdoor knotted border pillow is almost certainly a polyester-blend or 100% polyester outdoor fabric, chosen for weather and UV resistance. Polyester itself is chemically stable in normal use, but outdoor textiles often receive water-repellent finishes (water-repellent coating treatments) that may contain fluorinated compounds (PFAS) or other durable additives. West Elm does not publicly disclose the finishing chemistry of this pillow, making the presence of antimony (a flame-retardant nucleating agent sometimes used in polyester) or other treatments unverifiable.
The brand's record and disclosure
West Elm is a mid-market home furnishings brand under Williams-Sonoma Inc. The company has not published comprehensive chemical transparency reports or PFAS phase-out commitments comparable to leading sustainable furniture makers. West Elm does not disclose material safety data sheets (MSDS) or third-party certifications (Oeko-Tex, GOTS, bluesign) for most outdoor textiles, leaving buyers without independent verification of dyes, finishes, or heavy-metal content in pigments used on the border knot detailing.
How it compares in its category
Outdoor pillows in West Elm's price range typically lack certified chemical transparency. Competitors like Patagonia and REI Co-op outdoor textiles often carry bluesign or GOTS certification and disclose PFAS-free water-repellent coating alternatives. Budget outdoor pillows from big-box retailers rarely disclose finishes, while premium outdoor brands (Sunbrella, Ektorp) publish technical specs. West Elm sits in the middle: better than no-name imports but without the accountability of certified alternatives.
If you buy it
Before purchase, contact West Elm customer service directly and request confirmation that the pillow contains no fluorinated water-repellent coating treatments and no added flame retardants beyond what polyester naturally requires. Store the pillow indoors or under a cover during winter and heavy rain to minimize water saturation and mildew risk. Wash only with mild soap and water; avoid hot water and bleach, which can degrade polyester dyes and finishes. Replace every 2-3 years if stored outdoors year-round, as UV and moisture eventually compromise fiber integrity and may accelerate leaching of any residual finish chemicals.
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.”
water-repellent coating (water-repellent coating) treatments - undisclosed chemistry
Outdoor textiles typically receive water-repellent coating finishes; West Elm does not disclose whether this pillow uses PFAS-based or PFAS-free alternatives. Fluorinated water-repellent coating can release volatile compounds during storage in warm conditions and may leach into skin with prolonged contact.
Antimony in polyester fiber
No public record of antimony or antimony-based catalysts in West Elm outdoor textiles, but polyester manufacturing sometimes involves antimony trioxide as a polymerization catalyst. This is not reported as a concern for this specific product line.
Azo dyes and heavy metals in pigments
The knotted border detail introduces colored yarn that may be dyed with azo compounds or pigmented with lead/cadmium-containing colorants. West Elm does not certify dye safety or test for heavy-metal content in trim details.
VOC off-gassing from finish or adhesives
New outdoor textiles sometimes off-gas volatile organic compounds from water-repellent coating resins or thread adhesives, particularly in sealed storage. This is typically mild but may cause odor or minor respiratory irritation in poorly ventilated spaces.
Mildew and bacterial growth if stored wet
Polyester is hygroscopic and will retain moisture if not dried promptly after rain or washing. Prolonged dampness encourages mold and bacterial colonization, especially in seams and under the knot detailing where water pools.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
