Initially I was terrified, when one , then two more boxes arrived at my home. 
As I opened them, I thought of all the “some assembly required.”
To my shock and glee three boxes contained the 4 major components of the chair. Box one, the base. Box two the arm sets. Box three, the back. 
By the way the assembly instructions are in the pocket of the right arm. Yeah the arms labeling is reversed. No biggee. So put the arms in, the back in, figure out what to plug into what, and you have the best value for the money you. Can buy. 
Also congratulations to the team at Wayfair customer service. No, I didn’t find the instructions until I assembled the chair, however I did an initial on line query. It gave me a phone number to call. I did. Answered in less than 3 minutes. Emailed me the instructions. Easy . Best customer service experience I’ve had. 
That is saying that as a customer who hired and trained customer service agents, and ran call centers for years.
Well done Wayfair.
