West Elm Sunbrella Indoor/Outdoor Cast Pillow
Avoid until West Elm discloses Sunbrella's water-repellent coating chemistry or confirms PFAS-free status.
Sunbrella's premium outdoor fabric traditionally relies on PFAS-based water and stain repellency. West Elm provides no clarity on whether this pillow uses PFAS-free or legacy formulas.

What West Elm Sunbrella Cast Pillow is made of, ingredients and materials
This pillow uses Sunbrella acrylic fabric, a solution-dyed synthetic material known for UV and water resistance without heavy coating. The water-repellent coating (water-repellent coating) finish applied to achieve water repellency is the critical unknown, most commercial water-repellent coating finishes historically relied on PFAS compounds like Teflon-type coating or fluorocarbon chains, though some manufacturers have reformulated to alternatives not known to contain PFAS. Acrylic fiber itself is relatively inert and does not typically leach problematic chemicals during normal use. The hazard depends entirely on which water-repellent coating chemistry West Elm or Sunbrella chose, which is not publicly disclosed.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Undisclosed water-repellent chemistry on Sunbrella textiles historically contains PFAS; no independent testing or brand confirmation available for this specific pillow.
Source, ATSDR ↗Formaldehyde / VOCs
Acrylic fabrics may undergo formaldehyde-based resin bonding during manufacturing. Sunbrella's process is proprietary and not publicly detailed; off-gassing risk is low given acrylic's lower propensity than cotton, but not zero.
Source, ATSDR ↗Fiber shedding and microplastic release
Acrylic pillows can shed fibers through friction and weathering, especially at seams or if the cover develops pilling. This contributes to microplastic dispersal in outdoor/indoor environments; not unique to this brand but inherent to synthetic textiles.
What’s reassuring
Heavy metals
Sunbrella acrylic is solution-dyed (pigment added before fiber extrusion), which typically avoids surface azo dye application. No recalls or reports of dye bleeding or heavy metal content in Sunbrella for indoor/outdoor pillow lines.
Source, FDA ↗Flame retardants
Sunbrella acrylic does not require added flame retardants for residential use in the US. No evidence that West Elm applies additional FR chemicals to this pillow line.

The brand's record and disclosure
West Elm (owned by Williams-Sonoma Inc.) has not published detailed chemical disclosures for Sunbrella products or made a clear public commitment to PFAS-free water-repellent coating finishes. The brand has not faced major product-specific safety recalls for this pillow line. Sunbrella (owned by Glen Raven) is respected for durability but similarly does not transparently specify water-repellent coating chemistry on consumer-facing materials. Without direct confirmation, the assumption is conventional PFAS-based water-repellent coating, which was the industry standard for decades.
How it compares in its category
Indoor/outdoor throw pillows commonly use either acrylic blends (like this) or polyester with water-resistant finishes. Sunbrella acrylic is considered mid-to-premium in durability and UV fade resistance. Most competitor pillows face the same water-repellent coating disclosure gap; few brands explicitly state PFAS-free status. Natural fiber alternatives (cotton, linen) avoid water-repellent coating chemistry entirely but lack weather resistance and outdoor durability.
If you buy it
Store indoors or under cover during extended rain or seasons when not in use to minimize water absorption that would stress the water-repellent coating finish. Do not machine wash; spot clean with mild soap and water, and air dry completely. Inspect annually for pilling, color fading, or seam degradation, especially in intense sun exposure. If West Elm or Sunbrella releases PFAS-free certification, verify your purchase batch and consider replacement for peace of mind.
