My previous bookshelves are from Ikea, and one can easily tell that this one is an upgrade: It's very sturdy (somehow all my Ikea pieces are a bit shaky), and the assembling steps are similar to putting together an Ikea bookshelf. I did it on my own and it is easy but time-consuming (there are lots of nails to put in at the back). 
Somehow the color of the bookshelf is darker than the photo suggests. That's why I'm giving it 4 stars rather than 5. Overall, I'm happy with it.
