The chair is very comfortable and looks good.  The assembly was very difficult.  Hex bolts of various lengths were provided.  It would have been much easier if the heads of the bolts had slots that fit drill bits so that a cordless drill could be used for assembly.  In retrospect, I would have taken all the bolts to the local hardware store and replaced them with the same size bolts that would allow a drill bit to be used; the assembly would have taken one third of the time and have been much less frustrating.
