How do I find a quality couch that will last?

I’m looking to buy a new couch, but it seems the options are restricted to high-end designer furniture, or low quality discount furniture. I don’t want a discount couch that won’t last any longer than the one I have now, I want a piece of furniture that will be out of style and ugly, but still comfortable and functional when my kids are grown and move out. Where do I even start looking for a quality piece of furniture? Even if I pay for something from a higher end store, am I really getting something that’s better made than the discount furniture store’s product?
