I never write reviews, but unfortunately I have to. I spent an hour putting together the first chair and had no problem. It is actually very comfortable. Then I started working on the second chair. When I was assembling the right arm (part C) to the seat I noticed that the hole wasn't properly drilled where the (i screw) is supposed to go. I tried for 20 minutes until I took the right arm totally off to test it out with just the screw. Again, the (i screw) would not fit. I triple checked by checking the (i screw on the left arm and it worked perfectly. Now I'm 2 hours into my Saturday and need a new right arm to complete this chair wishing I had my time and money back. Please help.
