Upholstered furniture is typically made with wooden or metal frames, synthetic or natural foam cushions, and fabric coverings. Many conventional upholstered pieces contain flame retardants, PFAS (per- and polyfluoroalkyl substances), and phthalates, which can contribute to indoor air pollution and pose health risks, including endocrine disruption and respiratory issues. Composite wood used in furniture frames can also release VOCs such as formaldehyde. Choosing responsibly sourced materials and non-toxic treatments helps create a safer indoor environment.
