74 in by 19 in Outdoor Solid Polyester Tufted Chaise Lounge Cushion vs Topanga Armchair Cushion: which is safer?

Where these two actually differ

• We flag Azo dyes in polyester textiles and Microplastic shedding from fill and cover on the Blazing Needles and not on the Williams Sonoma.
• We flag PFAS in stain-resistant coating (reported separately; noted here for context), Microfiber shedding from base fabric, Formaldehyde in dyes or sizing (textile finishing) and Foam core degradation (if present) on the Williams Sonoma and not on the Blazing Needles.
• The Blazing Needles is Polyester fill with polyester cover where the Williams Sonoma is upholstery fabric with stain-resistant finish (likely PFAS-treated), which is most of the difference in these two grades.
• The gap is 40 points, wide enough that this is not a close call, and the Blazing Needles is the one to buy.
• We are less certain about the Williams Sonoma grade, at 45% confidence against 72%, because it discloses less.
