This took two of us about three hours to assemble, not the 45 minutes stated. The instructions were rubbish, and the pre-drilled holes were misaligned. I’d ordered one with a skirt and the extra bits were just added to the packaging with no holes drilled to add the skirt so I’m not using it. The only reason I didn’t return the bookcase was that friends had come from from two hours away to help. Next time I’ll spend more money and get a pre-assembled unit, I thought I could get away with buying a cheap bookcase as I only want it for a study but you get what you pay for.
