Banks Sleeper Sofa Foam vs Lucia 93" Recessed Arm Slipcovered Sofa with Reversible Cushions Fabric: 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 Wayfair.
• We flag Flame retardants (halogenated or phosphorus-based), Formaldehyde-releasing resins (in finishes and dyes), Azo dyes (heavy-metal-laden synthetic colorants) and Volatile organic compound (VOC) offgassing on the Wayfair and not on the Joybird.
• The Joybird is polyurethane foam where the Wayfair is polyester/cotton blend upholstery fabric, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Wayfair grade, at 45% confidence against 72%, because it discloses less.
