I love the astetic of this bookshelf and I also love the cabinet underneath for all my puzzles! The wheels included are pretty great thought- however, the bookshelf is slightly more flimsy than I anticipated and I personally would not dare to move the book case full of books on wheels. It's not built for movement w/ a full load.  

The entire shelf is FULL of books and it kind of wobbles back and forth while stationary (I just try not to mess with it). It hold up just fine. 

Honestly, I may buy a second - regardless of the slight flimsyness... It's super cute and I honestly just have a book problem lol
