Heck, even at the low end of not-garbage, a couch runs in the $1k range. Something from Bobs Furniture Outlet, for example.
Note, I love Bob's furniture. I have a couch from there I bought 10 years ago and it's absolutely the most comfortable couch I've ever had. My comment that they're low end is not, in any way, to insult the quality of what they have. Rather, they're not expensive (the same couch at a slightly more "name brand" place would have been twice the cost; for no increase in quality).
All sofas have labor and logistics. The more expensive ikea couches are as good as other big box couches, which is to say, they aren’t premium furniture.
Not really? Furniture is expensive. Once you move out of the garbage tier, that's not a whole lot of stuff.
