Banks Sleeper Sofa Foam vs Thomasville Slide Jack Sleeper Sofa: 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 Thomasville Furniture.
• We flag Flame retardants (chemical identity unknown), Formaldehyde in adhesives and resins and Volatile organic compounds (VOC) from padding, fabric dyes, and finishes on the Thomasville Furniture and not on the Joybird.
• The Joybird is polyurethane foam where the Thomasville Furniture is upholstered sofa, typically fabric or microfiber, 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 Thomasville Furniture grade, at 45% confidence against 72%, because it discloses less.
