How to get rid of chemical smell from new furniture?

Ventilate new furniture in a well-aired room or outdoors for 3–7 days, then apply baking soda or activated charcoal to absorb the VOCs responsible for the chemical odor.

The smell comes from volatile organic compounds released by adhesives, foams, and fabric treatments used in new sofa manufacturing, a process called off-gassing. Sunlight and fresh airflow accelerate VOC breakdown significantly. Baking soda sprinkled on cushions and left for several hours absorbs residual odor; activated charcoal bags placed nearby work continuously. Fabric sofas may need a light spray of white vinegar diluted in water, wiped dry, to neutralize stubborn compounds.

New furniture off-gassing typically peaks within the first 72 hours of unboxing.
VOC levels in new upholstered furniture can drop by roughly 50% after 3 days of ventilation.
Activated charcoal bags rated for 75–100 sq ft absorb furniture odors effectively within 24–48 hours.
Baking soda treatment: sprinkle, leave 8–12 hours, then vacuum thoroughly from cushion surfaces.
White vinegar dilution for fabric: 1 part vinegar to 2 parts water, applied lightly and air-dried.
