Westport Outdoor Lounge Chair Cushion Covers
Skip until West Elm discloses treatment chemistry or certifications.
Outdoor cushion covers typically receive water-repellent coating (water-repellent coating) finishes, historically PFAS-based. West Elm provides no chemical disclosure or third-party verification, leaving treatment origin unclear.

The full breakdown
What it's made of and why it matters
These covers are polyester fabric treated with a durable water and stain-resistant (water-repellent coating) finish, likely a fluorochemical or silicone-based formulation. Polyester itself is stable, but the treatment chemistry and any flame retardants applied to meet flammability standards are the real concern. Outdoor cushion covers often receive antimicrobial or mildew-resistant treatments as well, which may introduce additional chemicals. Without disclosure, you cannot know if the treatment contains PFAS, formaldehyde releasers, or other persistent additives.
The brand's record and disclosure
West Elm has not published detailed chemical disclosures or third-party certifications (e.g., Oeko-Tex, GOTS) for this product line as of available public records. The brand markets sustainability but remains silent on finishing chemistry and flame retardant sources for outdoor textiles. This opacity is typical across home furnishings retailers but represents a red flag for informed purchasing. West Elm has faced no major recalls specific to this product, but the lack of transparency on water-repellent coating and flame retardant chemistry is a material gap.
How it compares in its category
Outdoor cushion covers routinely use polyester with water-repellent coating finishes; West Elm's product is standard in construction. Premium alternatives (e.g., Restoration Hardware, Pottery Barn) often offer similar transparency gaps. Budget alternatives sometimes use untreated polyester or PVC, which sidesteps some chemical risks but sacrifices durability. Certified options (e.g., outdoor fabrics labeled Oeko-Tex Standard 100 or bluesign) exist but are rarer and pricier; this product does not appear to carry such certification.
If you buy it
Air out covers in sunlight for 48 hours after unboxing to off-gas any volatile residues. Wash before first use in cool water with mild detergent and hang dry; avoid high heat, which can accelerate breakdown of the water-repellent coating and any flame retardant resin. Replace covers if visible cracking, peeling, or discoloration of the treatment occurs (typically 2-4 years outdoors). Store indoors in winter to extend life and reduce UV and moisture-driven degradation of the finish.
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.”
Flame retardant chemicals (source unknown)
Polyester outdoor cushion covers sold in North America are likely treated to meet flammability standards. West Elm does not disclose whether brominated, phosphate, or other retardants are used, and some formulations can off-gas or leach under heat and humidity. Risk is low during normal use but higher if covers are heated (e.g., left in sun for extended periods) or stored in warm, damp conditions.
Water and stain-resistant (water-repellent coating) treatment chemistry
The stain and water resistance almost certainly involves a fluorochemical or silicone-based coating. Many water-repellent coating finishes historically contained long-chain PFAS; newer formulations use shorter-chain alternatives or silicone, but West Elm's silence means the specific chemistry is unknown. Off-gassing during initial use and potential leaching into soil during rain exposure are plausible but not quantif
Volatile organic compound (VOC) off-gassing
New polyester textiles with multiple chemical finishes (flame retardant, water-repellent coating, antimicrobial) commonly off-gas solvents and volatile residues for 48-72 hours after unboxing. Symptoms include odor and mild respiratory irritation. Risk is low outdoors (good ventilation) but higher if covers are stored or used indoors; airing out mitigates this substantially.
Polyester fiber shedding and microfiber release
Polyester fabric degrades under UV and mechanical stress, shedding microfibers into soil and water. This is not unique to West Elm but is inherent to the material. Outdoor exposure accelerates degradation, particularly if the water-repellent coating peels or cracks, exposing the underlying fiber. Microfiber pollution is an emerging environmental concern but poses minimal direct health risk to users.
Formaldehyde releasers in resin finishes
Formaldehyde-releasing resins are common in some durable-finish textiles but are less common in outdoor cushion covers than in apparel or bedding. No public recalls or safety alerts specific to West Elm cushion covers mention formaldehyde. However, without certification or disclosure, this hazard cannot be ruled out.
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.
