Where'd you get your couch?

I need a new couch. I've had an ikea couch for a decade. It cost $800 new, has had a good run but it's not particularly comfortable anymore and I'm ready to upgrade. I want a couch with longevity (at least 10 years) and online reviews don't help in ascertaining how long a piece of furniture will retain the comfort and integrity levels that justify the outlay because they are usually written just after the couch was purchased.

So, do you have a couch that you love? Or hate? How long have you had it? Where did you get it from? Where do you avoid?

I won't give anymore specifics on what I want and need as this might be useful to others with different requirements.
