What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
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.
PFAS
Water-repellent coating treatments on performance textiles historically relied on long-chain PFAS; Arhaus has not disclosed whether this pillow uses legacy PFAS, fluorine-free alternatives, or certified PFAS-free water-repellent coating. Without third-party certification or brand transparency, exposure risk cannot be ruled out.
Source, ATSDR ↗Microfiber shedding from polyester
Polyester outdoor pillows shed microplastics during use, particularly when rubbed or weathered. Arhaus does not advertise microfiber-shedding reduction (e.g., through tight weaves or special finishes), so this pillow likely releases fibers at rates typical for the material class.
Coating degradation and leaching
As the water-repellent coating wears (from sun, moisture, and friction), its integrity declines over 3-5 years. If the coating contains PFAS, degradation increases the opportunity for compounds to migrate into contact surfaces or the surrounding environment.
Mold and mildew growth
Outdoor pillows absorb moisture and can harbor mold or mildew if stored damp or in shaded, humid areas. Arhaus does not advertise antimicrobial treatments, so mold risk is standard for untreated polyester in outdoor conditions.
What’s reassuring
Formaldehyde / VOCs
No recalls or public complaints about formaldehyde odor specific to Arhaus Dawson pillows exist. Polyester fabrics can carry residual formaldehyde from manufacturing, but outdoor use and ventilation typically allow off-gassing within weeks.

What it's made of and why it matters
Arhaus Dawson pillows use polyester performance fabric treated with a water-repellent (water-repellent coating) finish. The specific water-repellent coating chemistry is not disclosed publicly. Polyester itself is stable and unlikely to leach under normal outdoor use; the risk centers on the water-repellent coating, which historically has used long-chain PFAS compounds, though newer alternatives exist. Without lab confirmation or certification, you cannot determine whether this pillow uses legacy PFAS, newer fluorine-free water-repellent coating, or something in between.
The brand's record and disclosure
Arhaus does not publish detailed chemical disclosure statements or PFAS-specific commitments on their website or product labels. The company has not sought third-party certifications (such as Oeko-Tex or GREENGUARD) that would verify water-repellent coating composition. This silence is not evidence of harmful chemistry, but it is a transparency red flag compared to peers like Restoration Hardware or Pottery Barn, which have begun phasing PFAS from outdoor textiles.
How it compares in its category
Outdoor performance pillows at this price tier typically use polyester with water-repellent coating finishes; Arhaus is not an outlier. Pillows certified PFAS-free (by third-party labs or OEKO-TEX Standard 100) are increasingly available from brands like Sunbrella or through secondhand markets, though they command premiums. Untreated linen or cotton pillows avoid the water-repellent coating hazard entirely but sacrifice stain resistance.
If you buy it
Use it outdoors only; do not bring it indoors regularly or store it in damp enclosed spaces where degradation accelerates. Spot-clean with cool water and mild soap; avoid dry-cleaning or high-heat washing, which can degrade the water-repellent coating finish and potentially increase leaching. Replace after 3-5 years or if the fabric becomes visibly worn, cracked, or faded (signs the coating is breaking down). Inspect seams and piping annually for mold or mildew growth, which signals moisture retention issues.
