Lovely shelf for our nursery, easy to build (think I managed it in half an hour!) didn’t need any fancy tools and everything came labelled. 
My only criticism and reason why it’s not 5 stars, is that it scratches easily, when I was tightening a piece my screwdriver slipped and scratched it but luckily I had some paint (not regular wall paint) to touch it up, so just be cautious when building it so you don’t scratch it either!
