More than half of all couches tested in a Duke University-led study contained potentially toxic or untested chemical flame retardants that may pose risks to human health. Among the chemicals detected was “Tris,” a chlorinated flame retardant that is considered a probable human carcinogen based on animal studies. “Tris was phased out from use in baby pajamas back in 1977 because of its health risks, but it still showed up in 41 percent of the couch foam samples we tested,” said Heather Stapleton, associate professor of environmental chemistry at Duke’s Nicholas School of the Environment.
