We always call this the Herman Miller chair. Never the red chair, or the red rocker. My father-in-law gave it to us many years ago. We didn't know it was a collector's item and for a while left it out on the porch. It's in our bedroom now, where it looks good and we try not to let it become a dirty clothes receptacle.
