Banks Sleeper Sofa Foam vs Haven 108in Sofa, Performance Modern Chenille Pink/Rosewood, West Elm: which is safer?

Where these two actually differ

• We flag Volatile Organic Compound (VOC) Off-Gassing, Flame Retardant Chemical Content, Formaldehyde in Adhesives and Binders and Foam Degradation Over Time on the Joybird and not on the West Elm.
• We flag Volatile organic compounds (VOC) off-gassing from synthetic fiber and finish coating, Formaldehyde in synthetic fiber processing or finish resins, Microfiber shedding from chenille pile degradation over time and Coating degradation exposing untreated fiber base on the West Elm and not on the Joybird.
• The Joybird is polyurethane foam where the West Elm is Performance chenille fabric with durable finish, 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 Joybird is the one to buy.
• We are less certain about the West Elm grade, at 35% confidence against 72%, because it discloses less.
