I finished assembly of this cabinet in about 4 hours and found it of moderate difficulty. You will need the recommended helper to assist in lifting the heavier sub-assemblies as you progress.  All parts were included and the 20 page instruction booklet was adequately detailed, but make sure you don't skip a step.  The only issue that I found was 2 scratches in one of the doors that must have occurred in the manufacturing process as they were painted over, but visible.  Otherwise, I would have given this item 5 stars.
