Yeah... maybe, theoretically you could assess if the expensive furniture was crap or not but in practice it's problematic, so you pay for some expensive crap.
Also the thing is that IKEA hollowed out the middle market, there is only cheap crap, medium crap but still crap, expensive crap that masquerades as expensive quality, and expensive quality.
The sofa that the author bought was not expensive quality, it was medium quality. Medium quality is good enough for just about anything but it probably isn't beautiful and high quality. The stuff you are seeing around from the old days in that are more sturdy than modern things are generally not the expensive stuff, because that stuff is still expensive. It's the medium stuff.
There is no longer any more medium stuff.
Thanks, IKEA.
On edit: feelings on matter may be colored by living in Denmark, which may be more affected by IKEA than other countries (proximity to Sweden, Danish habit of everyone agreeing on one way of doing things and then there is no other way)
