Skip or demand PFAS transparency. Sunbrella water-repellent coating likely contains PFAS.
Sunbrella outdoor fabrics are treated with water and stain-resistant finishes historically based on PFAS chemistry. The brand makes no public PFAS disclosure or commitment to PFAS-free alternatives.

What’s concerning
Category baseline

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.
Polyurethane foam off-gassing in cushion core
Product marketing does not specify foam type or flame retardant chemistry in the cushion core. Conventional polyurethane foam can off-gas volatile organic compounds (VOCs) including toluene diisocyanate (TDI) or flame retardants over its lifespan, particularly if exposed to heat or UV. Severity depends on manufacturing standard and material age.
Microplastic fiber shedding during use and laundering
Sunbrella acrylic, like all synthetic textiles, sheds microfibers during friction and washing. Outdoor cushions exposed to weather, foot traffic, and wind will release acrylic microplastics into soil and water over time. No product-specific shedding data is published, but this is inherent to the material class.
Mold and bacterial growth in damp foam core
Polyurethane foam retains moisture and is prone to mold colonization if cushions are stored wet, in shade, or in humid climates. Mold-contaminated foam can trigger respiratory irritation or allergic reactions during use. Regular inspection and dry storage are necessary preventive measures.
What’s reassuring
Heavy metals
Sunbrella's solution-dyed acrylic construction means pigments are integrated into the fiber during production, not applied topically. No azo dye or heavy metal pigment concerns have been reported for this product line, and this chemistry approach is recognized as lower-risk for textile color.

No records indicate formaldehyde-based finishes in Sunbrella acrylic fabrics. Performance-grade outdoor textiles typically use alternative cross-linking chemistry, though this is not independently verified for this product.

What it's made of and why it matters
Sunbrella fabric is solution-dyed acrylic, meaning pigment is locked into the fiber during manufacture rather than applied as a surface dye. This chemistry reduces risk of azo dyes and heavy metal pigment leaching compared to conventionally dyed textiles. The water-repellent (water-repellent coating) finish is the main concern, Sunbrella does not publicly disclose whether this uses PFAS-based or fluorine-free chemistry, which is standard industry practice for outdoor performance fabrics. The cushion core (typically polyurethane foam) and covers are not individually specified in product marketing.
The brand's record and disclosure
Sunbrella is owned by Glen Raven, a major performance textiles manufacturer. The brand has not published PFAS content or sourcing commitments in publicly available sustainability reports or product documentation. No product recalls for chemical hazards have been recorded for Sunbrella outdoor cushions. The brand does not certify to GOTS, OEKO-TEX, or other third-party chemical standards that would verify absence of restricted substances, which is typical for outdoor/marine-grade fabrics where performance is prioritized over transparency.
How it compares in its category
Sunbrella is the premium brand in outdoor cushion fabrics and is genuinely durable; most competitors use similar acrylic or polyester blends with equivalent undisclosed water-repellent coating finishes. Few outdoor cushion manufacturers voluntarily disclose PFAS use or offer PFAS-free alternatives at this price point. If PFAS avoidance is a priority, uncoated natural fiber options (untreated cotton/linen) exist but lack weather resistance and require more frequent replacement, offsetting environmental benefit.
If you buy it
Store cushions indoors or under cover during off-season to extend water-repellent coating finish life and reduce weathering that could degrade fabric integrity. Do not machine wash; hand rinse with water only, as detergents can strip the water-repellent coating. Inspect seams and stitching annually for mold or mildew growth in the foam core, which can occur if cushions are left wet or in humid storage. Replace when fabric shows pilling, seam separation, or color fading rather than waiting for catastrophic failure, as degradation may increase microfiber shedding into soil and water.
