I disagree with this sentiment, IKEA furniture is much more sustainable than artisanal furniture. Most of the "back in the day" furniture came from tearing down virgin woods. Sorting + shredding-recycling + making new "cheap particle board crap" furniture takes a lot of energy, but not a lot of non-renewable resources. With increased electrification this problem is being drastically reduced and the wood is sourced from re-grown tree farms (which also have their environment problems, but it is nowhere near as bad)

I am from Brazil and before the recent soy-growing deforestation of the amazon the #1 cause of deforestation was furniture-making. My parents have a really old dinner table made from high grade wood, is it is a pain in the ass to move and it has a ton of scuffs we can't be bothered to fix. Once my parents move we will probably throw it away. It lasted 40 years (with a big varnish rework around 25 years in) but the trees used to make it will never come back, my ikea table has been with us for around 8 years and still works fine.

Particle board tech has come a long way and it is much better than it used to be, IKEA particle board is consistently "okay" to "great", but other manufacturers it is not guaranteed. The only thing it lacks (by design) is the weight, particle board will be much lighter than "normal wood" furniture, which is both good and bad depending on the situation (some types of furniture you want to be heavy).
