If you have books falling over on or off a shelf, consider these steel bookends from Hay. They come in a set of three (in either a color mix, black, or white) and have different heights to work with your books. Quite similar to the Steel Bookends from the Jasper Morrison shop, which are a little less price wise if you’re in the UK.
