Quite a task to assemble this but it looks great.  The instructions are quite good but this isn't an allen-wrench-included type thing; you'll need a hammer and screwdriver and a good bit of elbow grease.  I recommend lubricating the short brown screws before putting them in.  They're hard to put in by hand otherwise.  I used a drill (the instructions said not to) and broke one screw.  Fortunately there was an extra.  Drawers slide smooth and have fine adjustment cams on the sides.

I would not rely on the lock.
