Assembly took 6+ hours and involved hundreds of hardware pieces and over 12 pages of instructions. I did successfully put it together (and it looks ok) but was literally angry by the time I was finished. From the look, I had assumed (my bad) that the top part would come assembled and I'll I'd need to do is put the base together and bolt on the top. So not the case. If you're solo, you will have a really difficult time with this product...you'll need a helping hand for the final assembly part of the process.
