The structure was alone relatively easy (2 hours for the main part + 1 hour for the doors), but you have to find out from the number of screws, for which parts these are intended as all screws look the same on the enclosed plan - which could be but easily done with a coffee and some rest.
The middle shelf is indeed included, but the brackets are missing it. It is additionally also comprise a rack for the center, which I have installed instead. It lacks the silver trim, which can be seen on the photo on both Article doors.
Despite the negative points I'm happy with the cabinet, and I give you a star deduction.
