Quite easy to build (although fiddly with the glue) and now it's up it looks great! We didn't attach to wall because we have a dado rail, so to keep it upright we put some heavy books in the bottom three holes and that seems to have done the trick. We have this on carpet, so if you were to put it on a hard floor it would probably be more secure.
Great buy! Especially if you have tons of DVDs like us
