What Williams Sonoma Ton 14 Side Chair Cushion is made of, ingredients and materials
Williams Sonoma outdoor cushions are typically polyester or polyester-cotton blends with a stain-resistant topical finish. The finish is the critical unknown, it is almost certainly a water-repellent coating (water-repellent coating) coating, which in the outdoor furniture industry has historically relied on PFAS-based chemistry (perfluorocarbons). Even if PFAS-free alternatives exist, Williams Sonoma does not publicly specify which one. Polyester itself is stable indoors but can off-gas volatile organic compounds (VOCs) during manufacturing and in the first weeks of use, especially in direct sun.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Outdoor cushion stain treatments are predominantly PFAS-based in the industry unless explicitly certified otherwise. Williams Sonoma has not disclosed or certified this cushion as PFAS-free, making PFAS presence probable though unconfirmed. Graded separately per instructions.
Source, ATSDR ↗Volatile organic compound (VOC) off-gassing from polyester
New polyester textiles, especially those treated with finishes, can emit VOCs in the first weeks, particularly if stored in warm or sunny conditions. Outdoors this risk is mitigated by ventilation; indoors before placement it could be elevated.
Heavy metals
Polyester textiles can be dyed with azo compounds or dyes containing cadmium, cobalt, or lead, especially in budget-to-mid-range products. Williams Sonoma does not certify dyes; outdoor use and minimal skin contact reduce dermal exposure risk, but not zero.
Source, FDA ↗Coating degradation and leaching over time
Water-repellent coating coatings degrade under UV exposure and washing, potentially releasing monomers or degradation byproducts (including PFAS if the finish is PFAS-based) into soil or water. Expected durability is 2 to 5 years before visual loss of water repellency.
What’s reassuring
Flame retardants
Outdoor cushions are not typically regulated for flame retardancy like upholstered indoor furniture, so no flame retardants are known to be added to this product. Risk is low.

The brand's record and disclosure
Williams Sonoma has not published a PFAS avoidance policy or third-party certifications (such as Oeko-Tex, GOTS, or Cradle to Cradle) for this product line as of public record. The brand is silent on stain-treatment chemistry across its outdoor cushion range. This is consistent with many mainstream home retailers, which treat chemical disclosure as proprietary and do not volunteer information unless pressured or required by regulation (California Prop 65, etc.). No major recalls or contamination incidents are on record for this specific product.
How it compares in its category
Outdoor cushions from Williams Sonoma are mid-to-premium priced and compete with brands like Pottery Barn, RH, and Frontgate, all of which maintain similar opacity on stain treatment. Budget alternatives (Wayfair, Amazon house brands) often use cheaper, less durable water-repellent coating coatings; higher-end certified brands (e.g., those with Bluesign or GOTS labels) are rare in outdoor cushion lines and command 20-40 percent premiums. Williams Sonoma's advantage is durability and design; its weakness is the lack of third-party verification of chemical inputs.
If you buy it
Store indoors during off-season to minimize UV degradation and weathering that accelerates coating breakdown and potential leaching. Avoid washing in a hot machine or high heat; gentle hand or cool-water rinse presents lower concern for the stain-resist finish. Inspect annually for pilling, fading, or loss of water repellency. Plan for replacement every 3 to 5 years depending on exposure; outdoor sun and moisture will degrade the fabric and finish over time. If stain-treatment disclosure becomes important to you, contact Williams Sonoma customer service directly to request chemical specifications before purchase.
