Nice grab.
I have spent many years mostly on my feet.
A co-worker ordered a stand-up desk, then did not like it.
I glommed on to it.
When busy I often ate my lunch standing.
Now retired, I read standing at a kitchen island. Not as good but it works.
When my wife is out, I eat standing.
My wife got me that chair about a decade ago when it wasn’t that much. I had a plywood standup desk for a few years at a jobsite trailer office . I liked it.
