Crate & Barrel Floral Blackout Window Curtain Panel vs Custom Seaton Textured Cotton Curtain: which is safer?

Where these two actually differ

• We flag Flame-retardant chemicals (unnamed), Volatile organic compounds (VOC) and odor from blackout coating, Microplastic and coating particle shedding over time and Formaldehyde-based finishing resins 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 Polyester with blackout coating (composition 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 45% confidence against 82%, because it discloses less.
