Do you know the year of this settee?

hi, i just got this sofa for free on craigslist , it is very heavy and i think it could be antique or vintage (to be honest i don't know the difference between the two) i just really love it. im curious however; what year it is from whether French or Victorian. I really love sofas from the 19th century. Im hoping this is one of them ...
also, we flipped the couch over and did not see any tags or markings of maker.
any ideas??
thank you!
