new furniture, flooring etc gives off VOCs, volatile organic chemicals and they can and do cause reactions similar to allergies. The gases will eventually go but you must keep the room well ventilated and windows open with a through flow of air
VOCs are dangerous, you can buy air purifiers that will help to remove them and some plants also help to keep the air clean but initially you must do all you can to ventilate that room and not stay in there
VOCs are everywhere in buildings and furniture and are a major cause of being unwell and worse
