DURHAM, North Carolina (NBC News Channel) -- Your couch could be harboring cancer-causing chemicals.
Researchers at Duke University tested the foam in more than 100 couches and found it contained chlorinated tris (try-ss), a chemical banned from children's pajamas in the 1970's because of health risks.
Experts say the flame retardant can seep out of sofas and into household dust, which is then inhaled. The chemical has been found to disrupt hormone production and cause cancer.
It was mostly found in sofas fewer than five years old. CLICK HERE
