New Couch = Chemicals?

I just purchased a new couch and had it placed in my living room when I realized I should probably google if the chemicals could be harmful (my first mistake.) I found some decent sources that worry me, but I'm unsure if I should really be worried or not. The couch is faux leather and polyurethane foam. One thing to complicate matters: my AC is currently broken so air isn't flowing through my (relatively small) home very well. I have fans going and multiple windows open but I'm worried inhaling the chemicals could be harmful to baby. I'm 14+4. What would you ladies do? I could place the couch in my open garage for a week or so, continue with the fans and open windows, or go stay somewhere else until Tuesday when my AC is fixed. Opinions?
