I've been searching for the perfect bar stool for quite so time. This was it for me. Sturdy, clean lines, welded frame, all you have to do is attach seat assembly to base. You will need a SKINNY/THIN   7/16 wrench to hold the bottom bolt while securing the washer with a regular 7/16 wrench. There were no instructions included so I sent an email to the manufacturer of the stools and got an answer within 30 minutes of my request.  Great purchase in spite of having to run down the directions
