Can sofa and upholstery fabrics off-gas toxic chemicals?

Upholstered furniture is a significant source of indoor chemical exposure. Sofa cushions typically contain polyurethane foam treated with flame retardants, while fabric coverings may be treated with PFAS-based stain repellents, antimicrobial agents, and formaldehyde-based wrinkle resistance finishes. These chemicals off-gas into indoor air and accumulate in household dust.

Studies have detected flame retardant chemicals in dust samples from virtually every home tested, with furniture being a primary source. Children who play on and around upholstered furniture absorb these chemicals through both inhalation and dermal contact with dust. The combination of heat from body contact and friction from sitting accelerates chemical release from treated fabrics.

When choosing upholstered furniture, look for GREENGUARD Gold certification for low chemical emissions. Opt for untreated natural fabric covers like organic cotton, linen, or hemp. If stain resistance is needed, choose fabrics with tightly woven textures that naturally resist spills rather than chemical coatings. Reducing treated textiles on furniture, where you spend hours daily, meaningfully lowers your household chemical burden.
