This was the easiest project I have built in awhile. I assembled it in 1/2 day. The instructions were complete and they gave you lots of the correct screws.

Also it is easy to modify to your needs or dimensions.  I built mine 8' wide and 3' deep and used the leftover 12" pieces of the 4'x8' sheet for the upper shelves. In hindsight I might have made it only 33" deep since the shelf platforms are 15" wide but it worked out just fine.
