Building the desk requires attention to detail to ensure that the right components, especially the various fixings/screws, are correctly located. Allow plenty of time, follow the (wordless) instructions carefully and take it slowly and steadily. The cabinet fitted together quite well, although the sliding shelves for the keyboard and the printer did not operate smoothly: this doesn't seem to be a major problem, though. With six castors the desk needs to be on a very level solid surface to ensure that the front two locking castors operate correctly. Note that there is no height adjustment with the desk, so make sure it suits whatever seating you plan to use with it.
