Charleston Slipcovered Grand Sofa 96" Polyester Wrapped Cushions vs Thomasville Slide Jack Sleeper Sofa: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) from polyester finishing and dyes, Flame retardants in cushion filling and wrapping, Polyurethane foam degradation in cushion cores and Azo dyes in polyester fabric on the Pottery Barn 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 Pottery Barn.
• The Pottery Barn is polyester cushion wrapping, upholstered fabric 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.
