Banks Sleeper Sofa Foam vs Katelin Slipcover Sofa in John Linen Sepia | John Linen Sepia: 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 Klaussner.
• We flag Formaldehyde in textile finish, Volatile organic compounds (VOC) off-gassing, Flame-retardant chemistry (undisclosed) and Coating or treatment degradation over time on the Klaussner and not on the Joybird.
• The Joybird is polyurethane foam where the Klaussner is John Linen, polyester blend upholstery, 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.
