Hi, I'm currently 21 and a half wks pregnant. My current sofa is really old and tatty and I need to buy a new one. I have read that you should be careful when buying new furniture when pregnant due to chemicals, such as fire retardants, and that they apparently off-gas for a period of time. Should I go ahead an purchase one anyway and keep the windows open for a week or so until the 'new furniture smell' disappears, or should I not buy one at all to be on the safe side? I would really appreciate some advice. Thank you, Sarah
