I have seen what I recall was called a Balan desk. It was a work top combined with a stand, you fitted into it in a semi- standing posture with support from knees and legs instead of buttocks. It supported the person upright, no leaning back. This was claimed to be good for those with back problems. One chap tried it for a few weeks then it vanished.

We have the option of converting the sectional "desktops" in our cubicles to standing height. When I worked in Sacramento, a number of us had done just that to one (or more) of a sections of our work areas, and the result was no less than amazing -

(1) If you're a walker/pacer when you're on the phone, or if you're in what I call "creative" mode, it is a definite plus to be able to walk up to your desktop and throw in ideas without having to sit down to do so.

(1.1) I also found when writing / rehearsing / editing presentations (something I did a lot of there), I could walk over, make the edit, and it was far less of an interruption than having a "desk height" workstation.

(1.2) - They were good enough to also include a tall desk chair (I think it was from an architectural supply house) that if you wanted to sit, you could (to jot notes or whatever). This was an added plus, as once I got used to it, I found the chair at that height was more comfortable than my regular desk chair.

(2) when I started using the standing height desk, the persistent back pains I had (likely from sitting in a desk chair for hours at a time) slowly and steadily vanished. Additionally, the early stage carpal tunnel pains diminished.

(3) People would come over for meetings, and ask how I pulled that off, or come over and take notes of my "standing desk".

While I still used my sitting desk for some tasks (formal meetings, vendor sessions, etc.), I found myself using the standing standard more and more.

Because of space considerations where I work presently (too much stuff, not enough room!) I can't set one of these up here - yet - but I implemented one at my home office, and, well... I can't say enough good about them.

I have never used on at work. I have a small standup desk in my home office. It has just a notepad on it and a pen.

I am a pacer when thinking, getting creative and as I get ideas I will walk over and write a note down. For this purpose I have loved it as I do not have to sit down to capture a thought. I can write and then pace some more.

I do not think I would care for it if doing anything where i plan to be in one place working for a length of time, but have never really tried it.
