Are certain substances in furniture truly toxic? I'm looking to purchase a sofa, but have been bombarded with all kinds of internet info about the toxicity of certain materials used to make sofas.  For example, polyurathane foam is labeled as toxic--is this true?  Is something like a blend of cotton/polyester and polyurethane toxic?
The polyurethane would have to be absorbed through your pores when you're in contact with the sofa. That's not going to happen easily? 
Theres a few tangent articles about the safety of these so called "cheap" sofas and mattress on livestrong and other websites. 
I'd say it's not a concern. Sofa on bro.
