> Correct me if there is evidence to the contrary, but I don't think humans were designed to sit or stand in one position for extended periods of time, habitually.

Hard evidence? I can't give you that. But look at all of the other mammals out there. Almost all of them spend substantial amounts of time sitting.

Traditional hunter-gatherer societies do almost of their work and food processing sitting down. Every hobbyist flint-knapper works sitting down.

The difference is they don't use chairs. Sitting in a chair is bad - just consider the risk of embolisms on long flights. It removes the need for your body to actively support itself and restricts motion. Anecdote of size one, but for me the biggest help was getting rid of the traditional "throne" chair and replacing it a very broad stool. I can comfortably sit cross legged on it all day. I'm constantly moving and shifting my weight forwards and back, leaning and reaching since I can't just roll a chair around.

It has required making some unusual furniture to use a computer comfortably. Like all of my keyboards are tilted the "wrong" way (away from me) with the front higher than the back. Much easier on my hands and wrists.

Like the horizontally staggered rows of keys, the traditional tilt is a skeuomorphism of a mechanical typewriter. There's no good reason for it to be preserved in electronic keyboards. Ergonomic keyboards are usually tilted the opposite way, with the front higher than the back. This better matches the natural tilt of your hands when you hold them in front of yourself.

Traditional hunter-gatherer societies blend into their daily schedule some amount of sitting, some amount of walking, also running, also climbing trees, perhaps swimming, etc.

It's the variety that's the key difference. We do the same thing (whether that be sitting in a chair, or felling trees in the forest) all day long, for decades. The monotonous schedule seems to be the problem; we're not evolutionarily adapted to it.

Got any pictures of this stool?

Yeah I'd be curious to see as well, if it's got some unique properties to it that would be useful to take example from :)

No, it is basically a boring hard flat piece of wood. Think of a bit of floor raised up off the ground. No back or arms.
