Looks great!  It was definitely a long process to put it together, but the directions were perfectly clear.  It is a really solid bookcase, nice and heavy.  I think it will be structurally sound, but of course only time will tell on that.  I have had many bookshelves over the years requiring self-assembly, and they always seem to fall apart at some point.  But this is definitely the most solid of any I have purchased in the past, and am hopefully it is going to stand the test of time...and not become the leaning tower.  It looks great and matches perfectly to a grey-wood TV stand I also purchased through Wayfair.
