You are treating me as if I don't understand a fundamental aspect of engineering (rude) when I am pointing out that previously such optimizations were far less tradeoffs, as evidenced by the case of earlier couches which didn't have this problem.

Obviously you will always have to make tradeoffs, it's the core of life. Previously these tradeoffs were not so harsh, and the penalty for spending a bit less was not a couch that broke in a year.
