Seconded. Used a Steelcase Leap (v1?) with headrest in my previous office for about 7 years, looked brand new.

Bought a Leap v2 w/o headrest to replace my "gaming chair" - well worth paying double. I wish I would've paid a little more money to get headrests because it's built into the chair back. To get an official one, you'd have to replace the entire back.

Edit: FYI - Gaming chair was a Secret Lab Titan. Fell apart under 3 years. What a POS and since it was just out of warranty, they wanted $160 to replace the defective seat (leather was peeling) and armrest (lumpy).
