Morris & Co. x Williams Sonoma Home Larkspur Curtain
Lower concern, plain woven textile with no disclosed durable water/stain treatment, but brand transparency on finishes is absent.
This Morris & Co. print curtain is a cotton-linen blend with no public evidence of PFAS-containing water-repellent coating or stain-resistant coatings. Williams Sonoma Home does not disclose finishing treatments, which limits full confidence. Untreated natural textiles carry lower PFAS risk than those with applied water or stain barriers.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This curtain is a cotton/linen blend, both natural cellulose fibers that do not inherently leach chemicals or off-gas volatile compounds when used as-is. The printed and dyed finish introduces the main chemical exposure pathway: synthetic dyes and any printing binders. No water-repellent, stain-resistant, or flame-retardant treatment is disclosed, which reduces the likelihood of intentionally applied synthetic chemicals like PFAS, heavy-metal catalysts, or halogenated flame retardants. However, the dyes and print chemicals used are not publicly specified.
The brand's record and disclosure
Williams Sonoma Home does not publicly disclose material testing, chemical certifications (e.g., OEKO-TEX, Cradle to Cradle), or restricted substance lists for this product line. The Morris & Co. collaboration is design-focused; neither brand publicly commits to phasing out hazardous dyes or finishes. This silence is not unusual for mainstream home textile brands but represents a missed opportunity for transparency. No recalls or contamination incidents are on record for this specific product.
How it compares in its category
Unfinished cotton/linen curtains without applied water or stain treatments are among the lower-chemical options in the category. Many competing curtains include polyester blends (risk of antimony residue), acrylic synthetics (higher VOC potential), or disclosed or undisclosed PFAS-based finishes. This product avoids those add-ons but does not exceed category norms in transparency; certified-organic or GOTS-certified alternatives exist but command higher prices.
If you buy it
Wash before first use to remove residual dyes and print chemicals; cold water and gentle detergent are sufficient. Avoid high-heat drying, which is unlikely to be necessary for curtains anyway. Inspect the print and dye for any odor after opening; mild off-gassing of solvents used in printing should dissipate within days in a ventilated space. Replace if dyes bleed excessively during washing (sign of poor dye fixation) or if the fabric weakens, typically after 3-5 years of normal use.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Synthetic dyes and residual solvents
Printed and dyed cotton/linen textiles may contain azo dyes (some of which cleave to banned aromatic amines under reductive conditions) and printing-solvent residues. No third-party testing or certification is disclosed for this product, so the dye chemistry and solvent removal are unknown.
Formaldehyde-releasing resins in print binders
Print paste binders sometimes include formaldehyde releasers to improve durability. This product does not disclose binder chemistry. Formaldehyde risk is generally lower in finished, properly cured textiles than in untreated paper, but off-gassing can occur, especially in newly manufactured fabric.
Heavy metals in dye colorants
Some synthetic dyes, particularly darker shades or reds, may contain or require heavy-metal catalysts (lead, chromium, copper) during synthesis or application. No testing data is available for this specific Morris & Co. print colorway. Risk is mitigated if dyes are properly fixed and the fabric is not chewed or heavily handled by children.
Microplastics from synthetic-blend contamination
This product is labeled as cotton/linen blend; if the linen content is genuine and polyester or acrylic is not present, microplastic shedding during washing is not a primary concern. However, label verification and full fiber composition are not independently certified.
Flame-retardant chemical additives
No flame-retardant treatment is disclosed for this product. Untreated natural-fiber curtains are not required to meet high flame-resistance standards in residential use, so intentional FR chemicals are unlikely. Risk would only arise if an undisclosed FR finish is present.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
