IKEA populates its display units (like bookshelves or living rooms, etc.) with real books. I was quite surprised to see many copies of Vikram Seth’s The Golden Gate translated into Swedish on my last visit there.
Speaking of IKEA, HTMLGIANT will tell you what to read in your IKEA chair (h/t to Bookslut). I’m surprised they didn’t choose the ubiquitous Poäng.
