But do they suck less than not having a sofa at all? I am a several-time-over beneficiary of cheap made-in-southeast-asia sofas. Shipped in a fridge-sized box right to my doorstep, assembled (by me) in ~15min, and perfectly serviceable. Is it up to the same quality level as a $5000 made-in-USA solid wood hand-woven twine-joinery (etc etc) masterpiece? No, but I couldn't have afforded that kind of sofa. And it didn't have to be hand-packed by a furniture transportation expert, and it didn't weigh 800 lbs.
I don't really see the "loser" here exactly - broke grad students, college kids, people in rural areas, and starving artists win; workers in developing countries win (the furniture factory sure beats the rice paddies); Instagram-sofa tech bros win. And gilded solid wood sofa makers can always market to the rich, who can afford to spend several months' worth of my rent cost on a piece of furniture.
