Chad, I remember a few years back you and I were discussing a swivel chair and designs through a few pm’ s back and fourth and how you were in the process of trying to figure out how to keep it light. I finally get to see what you got and looks very solid .Now is the chair adjustable in height and what are the gear looking things on each side. Is that for tilting it somehow? Looks like you been busy like a “Chemist” in a basement and glad you are bringing this swivel seat to life.
