Depending on how long your financing lasts: You pay off things for up to 30 years that you might not even have anymore - THAT would worry me more, and therefore a 0% financing at a furniture store would make much more sense.
It's like in the past when a car was always included in a mortgage - the vehicle was long at the junkyard, but you still paid for it. Usually, you don't notice that at first, but then it's just wishful thinking.
