All IKEA furniture I've bought has lasted a long time, but the meme is wrong, the reason it even exists is you can't buy better quality furniture for the same price, at least not by very much, it will cost a lot more if you want amazing quality.
Agreed, yet to find any ikea (or any non-ikea being fair) fail to hold whatever items i put into them... Sounds like you (OP, not person i am replying to), might ve storing something strange in them to fail often enough to complain about ALL ikea furniture...
Flat pack furniture traditionally had the relationship for being crap, in particular for missing pieces like a screw here or there, but when Ikea came along they did things properly. That was the reason they got so popular, they were so much better than the competition, and they forced others to up their game. I think they were the first to actually include extra screws, to cover the occassions when they weren't there, but these days their quality assurance is so good they just include the exact right amount every time.
I've done that once, and honestly wrote I needed four screws. A few days later I got an envelope with like, 20 screws. I get it, but still found it a bit funny.
