Sharland England French Ticking Stripe Blackout Curtain Panel vs Custom Seaton Textured Cotton Curtain: which is safer?

Where these two actually differ

• We flag PFAS in blackout lining treatment (DWR or flame retardant), Formaldehyde-releasing resins in finish curing, Coating degradation and microfiber shedding and Volatile organic compound (VOC) off-gassing on the Crate and Barrel and not on the Pottery Barn.
• We flag Formaldehyde resins in textile finishing, Azo dyes and heavy metal colorants and Dye migration or bleeding onto skin or other fabrics on the Pottery Barn and not on the Crate and Barrel.
• The Crate and Barrel is cotton/cotton-blend fabric with blackout lining, DWR treatment unspecified where the Pottery Barn is 100% cotton textile, no stated coating, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Pottery Barn is the one to buy.
• We are less certain about the Crate and Barrel grade, at 35% confidence against 82%, because it discloses less.
