The solid wood two tier revolving book case is exactly all that it says it is.  Solid wood.  Cut to precision.  There are several online videos clearly demonstrating (without the annoying non-stop chatter) how to build this bookcase, given that the single page instruction sheet in the box is somewhat inadequate.  The Philips screw driver that came with the bookcase is totally useless after using it three or four times. You will need to get one from your own tool box to build this.   
I have not yet decided whether to stain, paint or leave this as raw unfinished wood.  Leaning towards the latter.  Time will tell.  The two tier book case is extremely stable and in tandem functions as my end table.
