I'm a little disappointed because while the shelving unit itself feels really sturdy, when I got it into my space, one leg was slightly shorter than the other, causing the unit to rock back and forth. I had to stick something underneath the leg to get it to stabilize, which is more than a little frustrating (especially after it took so long to build). Despite that, the bookshelf is beautiful and does a great job of keeping things in order, due to the mid bars on the sides of each shelf. All in all, I'm pretty satisfied.
