Superb looking bookcase and quality to match. Item arrived in 3 boxes (total weight is around 50Kg!) between the times stated by the delivery company. 

The bookcase was assembled that evening taking around 2 hours in total. An hour more than the instructions suggested it'd take but we were limited for room and didn't want to damage anything. The provided instructions were clear and easy to follow. Each stage of assembly is numbered and has a plastic bag containing instructions and the required hardware to complete that particular step.

All in all very happy with our purchase and experience of shopping with Wayfair.
