So sorry to hear of your stinky purchase. If you want to purchase new try going to the Sustainable Furnishings Council website where you can find manufacturers and retailers who specialize in sustainably manufactured products.
Another option would be to purchase used furniture at a consignment shop or other similar outlet.
- Older furniture may have already off gassed what ever toxic substances they were produced with.
- You could also consider purchasing used furniture for the frame and have it reupholstered with natural latex or wool fillings and organic fabrics.
