A few of the bolts and nuts seemed to be cross-threaded but the manufacture promptly sent me replacements. Aside from 'interpreting' the pictures-only assembly instructions it went together relatively well. I took a casual pace of three weeks to assemble it and at this point I am pleased with the product and my assembly work. I have now built a redwood slatted floor and just finished with the first, of three, redwood plant stands inside, as well as adding a LED Light Strip inside it.
