The chair arrived the day after it was scheduled to arrive.  So much for a wasted day.  There were no directions for operating the adjustment levers.  I still couldn't figure out the middle lever and called the company.  The guy was not knowledgeable.  He recommended that the lever didn't function and that I should return it to Wayfair.  I found other YouTube videos that explained the levers.  I got it to work.  Wife is now happy.
