These are superb shelf units. Very sturdy, with fully adjustable shelves, and extremely easy to assemble (especially if free-standing). Really nice quality finish. The only advice I would give is that they are perhaps too big for wall mounting as they are A: very deep and B. extremely heavy, even without any books on. However all fittings, instructions, plugs and screws are provided if you decide to go that route, just make sure you have a couple of people to do it!
