Assembly was tricky because the holes didn't want to necessarily line up but I got them to with the use of my mallet, and I love the results. I bought this to allow my historian husband to move his books from one room to another easily, but so far it's moved everything else. I have to remember the cautions I read in other reviews about not putting too much weight in this.hat I'm going to do later is put a strip of one by two under each shelf in the center on edge to strengthen each shelf a bit and I think that that will be just enough so that I never have to worry about it carrying pretty much anything. Except concrete blocks or small elephants. I will draw the line there.
