Hi Electric:
I am sympathetic because I have reactions to new carpet, furniture (especially leather), and plastics.
New furniture can be treated with chemicals to be stain or fire resistant. It can have foam that is gassing or parts such as stuffing and wood laquer or plastic could be gassing off.
We bought a leather couch at macy's and had to return it within the 30 day money back guarantee period because of the strong chemical odor which never gassed off.
I also recently purchased a new vehicle which I don't drive regularly because it too is Gassing off. (it has a chemical/plastic odor which I can't stand).
I advise buying a couch that has already gassed off. Some dealers will sell the floor model if you ask. Try sitting on the floor model before buying to see if it bothers your allergies.
Good luck
