These chairs are comfortable and sturdy and they look great.  Assembly was easy but there are a few things to keep in mind if you want to avoid problems:

The “H” shaped foot rail assembly is made of square tubing with a nut welded inside, but not cleanly. On mine the threads on one nut was welded over during manufacture - however it’s hard to notice so I stripped out the bolt when I tried to put it together. Before putting a chair together I recommend looking it over carefully and gently starting a bolt to make sure the threads aren’t damaged. 

Also, not explained in the instructions, one side of the “H” shaped foot rail is 2cm wider than the other so flip it around before forcing the legs into position. The longer side goes in front and the shorter side in back.  

I’m waiting for replacement parts so I think customer service is good.
