Arhaus Wyatt Outdoor Water-Repellent Replacement Cushions
Skip until Arhaus discloses treatment chemistry or provides third-party testing.
Arhaus markets these cushions as water-repellent but doesn't publicly disclose the water-repellent coating treatment chemistry. Water-repellent outdoor textiles historically rely on PFAS-based coatings.

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
Manufacturer does not disclose whether water repellency uses PFAS-based chemistry (C6/C8 Teflon-family coating) or PFAS-free alternatives (silicone, wax, paraffin). Without third-party testing or brand statement, PFAS presence cannot be ruled out.
Source, ATSDR ↗Coating degradation and residue release
Outdoor cushion water-repellent coatings degrade under UV and weathering over 2-3 years. As coatings break down, treatment chemicals can migrate into skin contact zones or leach into soil during outdoor use, particularly if fabric is mechanically abraded.
Mildew and fungal growth if stored wet
Water-repellent coatings reduce but do not eliminate moisture absorption. Improper storage or use in humid climates can foster mildew colonization on the cushion core, which produces allergens and odors; replacement of affected cushions may be necessary.
What’s reassuring
Formaldehyde / VOCs
No public recalls or testing specific to Arhaus Wyatt cushions for formaldehyde in dyes or finishes. Polyester textiles with water-repellent treatments sometimes use formaldehyde-based curing agents, but absence of report does not confirm absence of hazard.
Source, ATSDR ↗Microfiber or fiber shedding during wear
Polyester outdoor cushion fabrics may shed microfibers into the environment during use and washing, but no specific data exists for Arhaus Wyatt cushions. Standard care (gentle washing, avoiding high-speed cycles) minimizes shedding.
The full breakdown
What it's made of and why it matters
Arhaus Wyatt cushions use an outdoor-grade fabric (likely polyester or polyester blend) treated with a water-repellent finish to resist moisture and mildew in outdoor settings. The specific chemistry of this treatment is not publicly disclosed by the brand, making it impossible to rule out legacy PFAS-based durable water repellents versus newer alternatives like silicone or wax-based coatings. Over time, outdoor UV exposure and weathering degrade water-repellent coatings, potentially releasing treatment residues or exposing untreated fibers beneath.
The brand's record and disclosure
Restoration Hardware (Arhaus parent company) has not published a public PFAS policy or disclosed the chemistry of water-repellent coating treatments in their outdoor textiles. The brand does not appear on major transparency initiatives (Outdoor Industry Association, CHEM Forward, or ZDHC Gateway). Arhaus cushions are marketed as high-end products, but lack third-party certifications (GOTS, Bluesign, OEKO-TEX) that would verify chemical safety standards.
How it compares in its category
Premium outdoor cushion brands vary widely in transparency, some disclose PFAS-free treatments or hold OEKO-TEX certification, while others (like this product) remain silent. Arhaus pricing suggests a design-led rather than safety-led positioning. Comparable outdoor cushions from smaller brands often provide material transparency and third-party testing that Arhaus does not, making this a mid-to-low transparency choice in a category where alternatives exist.
If you buy it
Store cushions in dry conditions when not in use to slow coating degradation and reduce mildew risk. Avoid high-heat washing or machine drying, as heat can accelerate treatment breakdown and potential off-gassing. Inspect regularly for water beading loss, color fading, or surface cracking; these signal coating failure and warrant replacement or professional re-treatment. Do not apply aftermarket water-repellent sprays unless you confirm they are PFAS-free, as reapplication is a common source of PFAS exposure.
