Ikea has some decent light fixtures and lamps and whatnot, now that I think of it. But we don't buy "serious" furniture there. We used it for those tall, narrow shelves for CD/DVDs, our TV stand, and a couple low-end dressers in our guest room. There's also some serviceable cookware to be found relatively cheaply there, too. Stuff like cake tins, frying pans, and like that.
I was just fitting the hardware in prep for assembling my shelves over the weekend. Yes the shelves are particle board, but the frame is definitely solid wood.
