Provided tools do indeed get you through the whole job. Paddle-type wrench can easily scratch paint on the black metal, so that's something to be careful about if you care about that sort of thing (I thought that might be me, but frankly I don't look under the desk to see). Thought assembly might be 45 mins but was twice that. Pull-out shelf works but not very well, which reminds me that there was no way to tell which was the correct way to put that in ... either way required force, and neither the shelf nor the instructions specified, so I picked a side and shoved really hard. Guess I picked the wrong way. Or maybe I can loosen some side bolts. Also: * Very Important * not to mix up the two kinds of bolts, as the more common (longer) kind will ruin the main desktop. It will still work, but the desk surface will no longer smooth, and that will be the fault of you, the assembler. I also ended up using a razor to cut the plastic coating around some thru-holes -- clearly, the manufacturer simply plastic-coated then punched the holes -- faster than drilling but leaves the plastic. Not a problem until you try to push a bolt through, and then the plastic makes it very difficult. But trim with a razor and voila! bolt goes through easy.
