I've always pictured the lever controlling the support as turning a non cylindrical (more oval shaped) tube within the seat. IF that was the case (and it probably isn't, since my mechanical acumen is questionable .. even on a "good day" lol) I'd have thought there was something that had come unwelded.

Your point of this being the result of a "mere" 20 years of use is probably right on. That put it into perspective for me as I just replaced the 5th computer chair used during the same time period.
