This is a beautiful piece! The assembly is facilitated by the use of cam-screws, which allow one to un-assemble, if needed, without much trauma.  I mistakenly put in a major component upside-down and was able to rectify without too much crying.  Instructions and ilustrations leave a bit to be desired, and the whole thing would be easier if the pieces had better labels indicating right side, up, down etc. But I love it!
