Contour 103.5" Grande Sofa, Fabric vs Banks Sleeper Sofa Foam: which is safer?

Where these two actually differ

• We flag PFAS in stain/water-repellent treatment, Flame retardants in fabric or foam filling, Volatile organic compounds (VOC) off-gassing and Coating degradation and chemical leaching over time on the Crate and Barrel and not on the Joybird.
• 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 Crate and Barrel.
• The Crate and Barrel is fabric with stain/water resistance treatment where the Joybird is polyurethane foam, 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 Crate and Barrel grade, at 45% confidence against 72%, because it discloses less.
