I should have read more of the reviews before purchasing.  The chairs were time consuming to assemble- misaligned parts, glue from packaging on over half the screws made it a challenge to thread into the parts, 5 end caps in the chairs were broken that I had to glue back on, and the Allen wrench was to short and luckily I had a longer one that helped in assembly.  I’m hoping when people sit on the chairs it straightens them out.  I can’t comment on durability.
