17" X 17" Replacement Seat Cushion - Knife Edge, Knife-Edge/Aquatic - Grandin Road
Insufficient disclosure; stain-resistant upholstery commonly uses PFAS without brand transparency.
This seat cushion claims stain resistance, typically achieved with fluorinated water-repellent coatings on upholstery. Grandin Road offers no PFAS details or third-party testing.

What 17" X 17" Replacement Seat Grandin Road is made of, ingredients and materials
This cushion uses a polyester-cotton blend fabric treated with a stain-resistance finish, which is typical for outdoor upholstery. The stain finish is almost certainly fluorocarbon-based (PFAS compounds), though Grandin Road does not disclose the specific chemistry. Polyester itself is stable under normal use, but the applied treatment is where chemical leaching and off-gassing risk concentrates. Outdoor cushions face UV exposure and temperature cycling, which can degrade the protective finish over time and increase the potential for fiber shedding and finish breakdown.
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.
Stain-resistant finish
Stain-resistant finishes are a common PFAS use.
PFAS
This cushion's stain resistance is almost certainly applied via fluorocarbon chemistry; no brand disclosure confirms this, and outdoor polyester upholstery almost universally uses such treatments. Leaching and off-gassing risk is elevated in sun and wet conditions.
Source, ATSDR ↗Microplastic shedding from polyester blend
Repeated washing, UV exposure, and mechanical wear of polyester-cotton blends can release microfibers. Outdoor use and weathering accelerate this process. Shedding is typically minimal with care but increases as the fabric degrades.
Coating degradation and chemical release over time
The stain-resistance finish is not permanent and degrades under sun, heat, humidity, and washing. As it breaks down, both the fluorocarbon compounds and any solvents or carriers may leach into contact surfaces or the environment.
What’s reassuring
Formaldehyde / VOCs
No formaldehyde release has been reported for this product or brand. However, polyester-cotton blends with applied finishes may contain trace formaldehyde in dye carriers or resin binders; no testing or disclosure is on record.
Source, ATSDR ↗Heavy metals
The cushion is described as 'Aquatic,' implying a blue or water-tone dye. No recalls or test results for heavy metal contamination in Grandin Road textiles are on record, but synthetic dyes can occasionally contain trace cadmium or lead depending on supplier and dye chemistry.

The brand's record and disclosure
Grandin Road is a home furnishings retailer without published certifications for chemical safety, sustainability, or PFAS avoidance on this product line. The brand does not disclose stain-resistance chemistry on product pages or care labels, which is standard industry practice but leaves consumers without information about fluorocarbon content or alternatives. No specific recalls or chemical safety controversies tied to Grandin Road cushions are on public record, but the silence on stain-finish composition is a significant transparency gap.
How it compares in its category
Most outdoor replacement cushions at this price point use polyester blends with generic stain finishes and offer no chemical disclosure. Alternatives with explicit PFAS-free or OEKO-TEX certification exist at similar or slightly higher prices from brands like Sunbrella or certified outdoor brands. This product sits in the middle, conventional chemistry, no third-party verification, and no commitment to transparency that would distinguish it from lower-risk options.
If you buy it
Wash covers by hand or gentle machine cycle in cool water; avoid hot water, bleach, and high heat, which can accelerate finish degradation and chemical leaching. Store indoors during off-season to reduce UV and temperature stress on the fabric. Plan to replace the cushion every 3 to 5 years, depending on sun and moisture exposure, as the stain finish will wear and fibers may begin to degrade. Never machine dry or iron; air dry only. Inspect for pilling, color fading, or water pooling as signs the protective finish is failing.
