I need the king of swivel seats

[Chad Orde]

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. 

Keefer,
HAHA been a slow go friend. I have been hunting out of it for a few years now and making slight tweaks to the design. 
To answer your question each leg independently adjusts for height by pulling the leg down and ratcheting up or down. The first set of legs are a little to short so I am adding 3" to them and adding larger feet too.
I started with a spring and now am using a tension band instead.

WOW! That looks like the jump seat out of a jet fighter... very cool!

I hope your design comes to fruition.

Chad, that seat looks sweet!

I actually won the millennium G100 in September and have taken it out a dozen times or so this season. Really liking it. Definitely not heavy at all, but the carry strap needs some work. Kinda digs. Sets up and tears down easily. Can sit in it flat (no legs) or all the way up or in between. Pretty comfortable.

Lots of good ideas here.
