Another for Ekrones or Eames. When buying my current "Listening Chair" I took height measurements and identified the optimal location for my head. Also, the headrest was a issue. I wanted one but preferred adjustable so I could keep it low. The Ekrones fit the bill but I was not prepared for the cost. My wife talked me into it. She is a Safety Engineer and performs Ergonomic assessments for employee work stations among her other duties. Our discussions came down to the following. I spend a lot of time in a chair so don't cheap out. Dam woman knows me all to well.
Good Luck
