Avoid until brand discloses the coating formula or provides independent testing.
Outdoor seat and back cushions typically use polyester with water-repellent finishes historically based on PFAS chemistry. The brand will not disclose the coating type or PFAS status.

What Three Posts Indoor/Outdoor Cushion is made of, ingredients and materials
This cushion is polyester or polyester blend fabric with a water-repellent coating (water-repellent coating) finish applied to the outer layer. water-repellent coating treatments historically relied on PFAS "forever chemicals" (PFAS) to repel water, though some manufacturers have shifted to fluorine-free alternatives. The cushion fill material (foam or fiberfill) is not specified in available product data, which limits full material assessment. Outdoor Voices has not disclosed which water-repellent coating chemistry is used in this specific product.
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
Polyester outdoor cushions routinely use PFAS-based water-repellent coating treatments. Outdoor Voices has not disclosed whether this product uses legacy PFAS or fluorine-free alternatives, leaving exposure risk unquantified. water-repellent coating coatings leach gradually through washing, weathering, and landfill decomposition.
Source, ATSDR ↗Polyester microfiber shedding
Polyester textile cushions shed microfibers during use, washing, and weathering, particularly if cover seams degrade. These fibers accumulate in soil and water. No specific data on this product's shedding rate, but risk increases with outdoor exposure and with any water-repellent coating that stiffens or cracks the fabric.
What’s reassuring
Azo dyes in colored polyester
Outdoor Voices cushions are typically available in neutral earth tones (gray, tan, beige). Industry standard polyester dyes used for these colors are not known to contain restricted azo compounds, though no testing certification is published for this product line.
Flame retardants
Cushion foam or fiberfill is not specified in available product information. If foam, regulatory flame retardant standards (TB117 or TB117-2013) may apply depending on manufacturing region, but no hazardous flame retardant content has been reported for Outdoor Voices cushion fills.
Source, EPA ↗VOC off-gassing from coatings and adhesives
New polyester cushions may emit volatile organic compounds from water-repellent coating finish and any adhesives used in seam construction. This is typically mild for outdoor textiles but has not been independently tested for this specific product. Off-gassing dissipates over weeks with air circulation.
How is this PFAS grade calculated?
The brand's record and disclosure
Outdoor Voices is primarily a direct-to-consumer activewear and lifestyle brand with limited public transparency on chemical suppliers or testing protocols for home goods. No industry certifications (GOTS, OEKO-TEX, GREENGUARD) are listed for this cushion line. The brand has not published a PFAS policy or confirmed transition to fluorine-free water-repellent coating treatments in publicly available materials. This silence is a significant gap given the well-established PFAS hazard profile in outdoor textile water-repellent coating finishes.
How it compares in its category
Indoor/outdoor cushions from major retailers vary widely, some brands (REI, Patagonia, Pottery Barn) disclose fluorine-free water-repellent coating or provide testing data; others remain silent like Outdoor Voices. Untreated polyester cushions are common alternatives but lose water resistance. PFAS-conscious consumers typically prioritize brands with explicit fluorine-free commitments or third-party certification, which this product lacks. Price positioning suggests this is mid-market, not premium transparency tier.
If you buy it
Wash infrequently and use cold water to minimize water-repellent coating leaching into soil and waterways. Avoid high heat when drying; air-dry in shade. Store indoors during off-season to reduce outdoor UV and moisture exposure that accelerates coating wear. Inspect annually for seam degradation or fabric pilling; replace if cushion cover becomes compromised, as interior foam may shed microfibers. Contact Outdoor Voices directly to request water-repellent coating chemistry documentation before purchase if PFAS exposure is a household priority.
