This bookcase is a lovely piece once assembled. In my opinion, assembly required for this bookcase is not recommended for those who by temperament or circumstance need an especially quick process with only a few pieces. The assembly steps were pretty well described and all pieces required were included. I'd say two people, dedicated space, 30 minutes, and a screwdriver are required to assemble this piece. In our case, we found that we did need to use our own drill to create missing pre-drilled holes for one small piece, one of the two short, mid-shelf supports between the outer rails.
