Co. Perry 71" Fabric Comfort Queen Sleeper Sofa vs Banks Sleeper Sofa Foam: which is safer?

Where these two actually differ

• We flag Formaldehyde resins in fabric finish or backing, Azo dyes in synthetic or blended upholstery, Flame retardant chemicals (brominated or chlorinated) and VOC off-gassing from foam, glues, and finishes on the American Leather 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 American Leather.
• The American Leather is Fabric upholstery (fiber composition unspecified) where the Joybird is polyurethane foam, 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 American Leather grade, at 35% confidence against 72%, because it discloses less.
