Then in order to not be hit by a UDRP, you need to be very careful. Don't use it for their industry and park in on a blank page (you currently have it showing furniture ads which is an easy way for them to win bad faith against you). If you put a for sale page on it, suggest its use in other industries.
Also, do not approach them as they will win an easy battle against you they know anything about domain related laws. If they approach you, that is not a sign of bad faith on your part - but make no mention of any awareness to their TM or right to the name (or even existence as a company prior to reaching out to you). Argue its merits as a brandable without emphasizing furniture, etc. They may try to get you to admit something that they then use in a UDRP. Be friendly, polite, but also smart about it.
Personally, I would get rid of such a domain since its main brandable use is sofas anyway and its could be a big pain with legal issues... but I've hung onto a few that I found had TMs in obscure countries after I bought them, too.... if you can think of another industry, they go for it and market it for that.
But again, a lawyer can help you much more (or the legal forum here at the very least).
