While I had read other reviews stating that this workstation took many hours to assemble, I didn't really expect it to take all day for me and my husband to finish the project. However, it did take ALL day (with a 2 hour break for lunch). The end result is a beautiful piece of furniture, but the assembly was challenging, to say the least, and frustrating at times. All of the pieces were nicely labeled, as was all of the hardware. The instructions had nice illustrations, but there were multiple times that the diagrams switched orientation without warning, causing us to assemble something backwards (for the record, I'm an engineer, so reading diagrams is not a problem for me). Also, it is a very LARGE piece of furniture, so it was rather unwieldy to assemble at certain stages. We also had issues with the drawer slides, but Overstock replaced them quickly, without question. Overall, I am happy with the unit, and it definitely serves the purpose for which I purchased it. It has a great color, and is very sturdy. Just be prepared for a long assembly process.
