Dear @desktopguy my comments re. V1 Leap - having owned them as well - is due to my experience only. I had several of the V1 and a) they are very bulky and heavy, b) the v2 not only lightened the chair, but it enhanced some of the ergonomic comfort, they are cooler (more breathable) than the very thick seat and back of the V1, "in my opinion". I can sit comfortably in the V2 for hours (too long, in fact!) unlike most chairs. You are 100% correct, the standard model does not include a headrest but one is available. As I began, I noted "aesthetics aside".
In my opinion. 😇
