Revere Today Sleeper vs Thomasville Slide Jack Sleeper Sofa: which is safer?

Where these two actually differ

• We flag Flame retardant chemical exposure (polybrominated or organophosphate compounds), VOC and aldehyde off-gassing from foam and adhesives, Fabric dye and finish chemical residue (azo dyes, formaldehyde resins) and Foam degradation and microparticle shedding over time on the American Leather 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 American Leather.
• The American Leather is upholstered furniture with fabric covering and foam core 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.
