Given that Ikea is legally run and registered as a non-profit charity, I think that the term is fairly meaningless at this point. We can only judge them by their actions, just as we do any other company.
Not for profit and non-profit are actually different in different tax and law scenarios. I'm not going to try and butcher the explanation, but it pretty much boils down to how employees get paid and expenses get deducted- which, in my opinion, has made me look at not for profit companies as companies that want to appear nicer than they really are.
That sounds like a US tax law distinction, but the IKEA structure is non-US (as are the owners/founders).
