I have IKEA furniture that's lasted for decades. It's value-optimized, but it's usually well designed; if you put it together properly, it will last.
This chair for example is way stronger than it has any right to be. I’ve seen it used in a ton of cafes so it clearly holds up to heavy usage https://www.ikea.com/au/en/p/taernoe-chair-outdoor-foldable-...
The look and price feels like it should be a flimsy piece of junk but in reality it’s incredibly solid.
On the other hand, I bought a dresser with a lot of particle board and, no, it's by no means well made. But it's in a bedroom and it works. I could have spent 4x (or more) for a nicely made hardwood dresser from a good New England brand. But even getting it into the bedroom upstairs might have been a bit of an adventure.
