I have tons of Ikea furniture. The only things that haven’t held up were a cheap $40 coffee table, and a set of dishes. Everything else has been great for years- all of our beds, several Henmes dressers, two couches, bookshelves… I’m sure I’m forgetting stuff. And we are a family with 7 people, 2 dogs, and 3 cats.
If you buy their cheapest stuff, it is going to last for like a year or two. But their more expensive things are great, imo.
