We bought 2 sets, a total of 4 chairs.  I found the assembly to be fairly easy.  The only step I inserted myself was to make small pre drill hole and added wood glue when putting together the bottom of the chair where your foot was rest on.  I do plan on tightening the hardware every few months to be in the safe side.  The chair description on the site was accurate to what we received and cost per chair was reasonable.
