Extremely easy to put together - took me about 15 minutes at most.  Problem was the pre-built part: the metal bars of the frame beneath table were not properly screwed into the table.  As a result, the table pops in and out of the frame.  When I tried to tighten the screws, the head of the screw snapped off with the threaded part stuck in the socket.  Now I cannot stop the table from moving around...otherwise an okay table
