My husband and I got the 4 shelf bookcase for our 11yo son's room. I wanted something solid and sturdy. I wasn't disappointed. This bookcase Also comes with an attachment that you can attach to a stud in the wall for further stability (though it was pretty sturdy without it). It was very easy to put together. All of the piecesholes lined up nicely. It only took my girlfriend and I about 20 minutes. Prompt delivery. Satisfied customer.
