Co. Perry 71" Fabric Comfort Queen Sleeper Sofa vs Thomasville Slide Jack Sleeper Sofa: 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 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 Fabric upholstery (fiber composition unspecified) 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.
