What Williams Sonoma Santa Barbara Side Cushion is made of, ingredients and materials
The Santa Barbara cushion is a polyester-covered cushion, likely filled with polyurethane foam or shredded polyester fibers. Polyester as a cover material is chemically stable once manufactured and does not typically leach harmful substances during normal outdoor use. The interior foam may off-gas volatile organic compounds (VOCs) during the first few weeks, but outdoor exposure and ventilation minimize this compared to indoor furniture.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
VOC off-gassing from polyurethane foam fill
New polyurethane foam may release VOCs (including toluene diisocyanate residuals) during the first 2-4 weeks. Outdoor placement and air circulation mitigate this; levels are not expected to pose acute health risk in typical use.
Degradation and microparticle release under UV
Extended outdoor exposure without cover causes polyester fabric to break down, potentially releasing fibers. This is a material lifecycle concern, not a chemical toxicity issue, but warrants seasonal storage.
Mold and bacterial growth in moist conditions
If left wet or in high humidity without drying, polyester/foam cushions can support mold and mildew, which pose respiratory and allergenic risk. Regular drying and storage prevent this.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Azo dyes in polyester fabric
No specific information on dye type or restricted substances testing is available for this product. Polyester fabrics may contain azo dyes; no recalls or warnings have been documented for Williams Sonoma cushions on this basis.
Formaldehyde / VOCs
Polyester cushion covers may include formaldehyde-based water-repellent treatments; none have been identified or recalled for this product. Outdoor exposure and ventilation would limit inhalation if present.

The brand's record and disclosure
Williams Sonoma does not publish detailed chemical disclosure or safety certifications for most home furnishings. The brand has no documented major recalls or controversies specific to outdoor cushions or chemical safety. No third-party certifications (OEKO-TEX, GOTS, etc.) are listed for this product, which is typical for mass-market outdoor furniture in this price range.
How it compares in its category
Outdoor dining cushions in this segment (mid-range retail) rarely undergo rigorous chemical testing or certification. The Santa Barbara cushion is representative of standard polyester-covered options; premium alternatives may use solution-dyed polyester (lower dye leaching risk) or certified organic fills, but those are uncommon at this price point. Budget options with vinyl covers or untreated fabrics carry similar or marginally lower risk profiles.
If you buy it
Store indoors or under a weather cover during off-season to prevent mildew and UV degradation, which can break down the polyester coating and release particulates. Rinse with mild soap and water; avoid high-pressure washers that can degrade seams and coatings. Replace cushions when fabric shows cracking, fading, or flaking, typically within 3-5 years depending on sun exposure. Do not expose to direct flame or high heat sources.
