74 in by 19 in Outdoor Solid Polyester Tufted Chaise Lounge Cushion vs Santa Barbara Club Chair 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 Stain-resistant finish (likely PFAS), Flame retardant chemicals, Synthetic fiber shedding and microfiber release and Coating degradation and leaching on the Williams Sonoma and not on the Blazing Needles.
• The Blazing Needles is Polyester fill with polyester cover where the Williams Sonoma is Upholstered cushion with unknown stain-resistant finish, 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 35% confidence against 72%, because it discloses less.
