Difficult to put together by myself e.g. I had to place a 4 ft. shelf  over the side posts while holding it almost over my head. Shelf is quite sturdy but I couldn't get the back pieces (to stop things falling off the shelf) to fit so I left them out. Instruction booklet and even on line didn't provide much information.
However I am hoping that when I can get a second set of hands to help maybe I can get the back pieces installed and the top shelf put on.
Nice looking shelf though and it holds a lot.
