What 19" X 17-1/2" Replacement Grandin Road is made of, ingredients and materials
This is a knife-edge canvas cushion, most likely a cotton-polyester blend typical of outdoor furniture upholstery. Canvas is a tightly woven, naturally durable fabric that resists puncture and UV degradation better than lighter fabrics. The coating and finish applied to outdoor canvas (if any) determine whether flame retardants, formaldehyde resins, or other treatments are present; Grandin Road does not publicly disclose finish composition for this item.
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.
Formaldehyde / VOCs
Outdoor canvas often receives formaldehyde-based mildew and rot inhibitors; Grandin Road does not disclose finish chemistry. Off-gassing is typically minimal in outdoor use due to air circulation, but upholstered cushions stored indoors may release low levels when new.
Source, ATSDR ↗Flame retardants
No public data on whether this cushion meets fire code via inherently non-flammable weave or applied chemicals. If treated, brominated compounds may leach in contact with skin oil and perspiration over months.
Source, EPA ↗Microbiological growth (mold, mildew, bacteria)
Any outdoor fabric cushion stored wet or in humid conditions develops mold; canvas does not prevent this. Damp cushions can harbor pathogenic bacteria and trigger respiratory irritation in sensitive users. This is a maintenance and storage issue, not a manufacturing defect.
Microplastics
If blended with polyester, the cushion may shed microfibers when washed or abraded over time. Shedding is minimal in outdoor use but increases indoors. No Grandin Road-specific data exists; this is inherent to polyester textiles.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Canvas white colorant is unlikely to contain hazardous azo dyes (which are restricted in EU textiles); no recalls or safety alerts exist for Grandin Road cushions. Risk increases only if the product is dyed post-purchase with non-certified dyes.

The brand's record and disclosure
Grandin Road (owned by HSN/Evine Live) does not maintain a published safety materials disclosure or PFAS/flame retardant transparency policy specific to furniture cushions. No recalls, lawsuits, or regulatory actions tied to this product line are on record. The brand's silence on chemical treatments means you cannot verify whether the canvas received formaldehyde-based mildew inhibitors or brominated flame retardants, common in outdoor textiles.
How it compares in its category
Replacement cushions from mass-market furniture retailers fall into a middle tier, cheaper than certified-organic outdoor cushions (which would disclose natural finishes), more transparent than unlabeled big-box alternatives. Canvas presents lower concern than solution-dyed acrylic or polyvinyl chloride (PVC) for outdoor use because it is not a material linked to phthalate leaching when wet. Budget cushions often skip third-party testing, so this product offers no advantage over comparable Pottery Barn or Wayfair equivalents in documented safety.
If you buy it
Store indoors or under cover during rain and winter to prevent mold growth and fabric rot; wet cushions create anaerobic conditions that promote microbial colonization. Replace the cushion if the canvas tears, seams split, or mildew persists after cleaning, as these are signs of degradation that may allow padding underneath to absorb moisture and harbor bacteria. Wash covers with mild soap and water; avoid bleach, which accelerates UV damage to polyester fibers. Inspect the zipper and knife-edge stitching annually for fraying.
