This bookcase comes in a flat pack. Assembly required. The instructions weren't 100% accurate: said the side panels would be labeled left and right, but they weren't; also, an incorrect number was given for the small Philips head screws in the hardware package. Main drawback was in the side panels, where a number of unnecessary and unused pre-drilled small screw holes are present; I had to fill these in after assembly because I bought the white finish and the screw holes were very visible.

Pros: Fairly easy assembly, good value for money
Cons: The instructions not 100% accurate, and some unnecessary and unused pre-drilled screw holes in the side panels
