Very much wish I hadn't purchased this. Very flimsy and rickety material...whole thing is held together with long screws into MDF and the locking screws in the other piece. Bookcase wobbles despite putting it together right. Backboard is held together with white duct tape, which can either face to the outside or inside, but either way, you're going to see it. Removing the "mandatory" (child tipping hazard) sticker left two holes in finish.  Nonetheless, it was only bookcase I could find that fit the right size measurements for a very small space, so am reluctantly keeping. If you have more parameters, don't get this bookcase.
