I was driving my car today and it occurred to me that the seat is pretty darn hard behind my head. I know; I should be wearing a helmet in conjunction with the high back Kirkey seat. I'd look pretty silly doing so on the street. Has anyone fashioned a padded headrest that slips over the top of the seat? I'm picturing high impact foam covered with black tweed. I'm curious if it's been done. I can't find any solutions online.
