Some are worse than others. Every time I have to dis/re-assemble our IKEA bedframe, it's a struggle to figure out how the weird spinny locks work - which way to turn them, are they actually engaging? did I strip something? why don't I just go buy a real bed frame? The basic stuff like bookshelves, coffee tables, chairs, maybe desks are pretty easy. But I put together a metal filing cabinet from IKEA once, and it was like a 2 hour ordeal for a piece of junk.
