When shopping for sustainable office furniture, you should look for pieces made of natural, organic, or recycled materials like wood, bamboo, cork, cotton, hemp, or metal. Avoid furniture made of synthetic, toxic, or non-biodegradable materials such as plastic, vinyl, or foam. Additionally, check the labels and certifications of the furniture to verify its environmental and social standards. The FSC (Forest Stewardship Council) certification guarantees that the wood used in the furniture comes from responsibly managed forests that conserve biodiversity and protect the rights of indigenous people and workers. The GREENGUARD certification verifies that the furniture meets strict standards for low chemical emissions and indoor air quality. The Cradle to Cradle certification evaluates the furniture's design, materials, manufacturing, use, and end-of-life cycle based on five criteria: material health, material reutilization, renewable energy, water stewardship, and social fairness. Finally, the BIFMA (Business and Institutional Furniture Manufacturers Association) certification assesses the furniture's durability, safety, ergonomics, and sustainability based on various performance and environmental indicators.
