Can’t Stand to Sit Too Long? There’s a Desk for That

A writer who likes to shift positions while he works tried out a work station that, with a push of a button, adjusted to his sitting or standing height.

When there were other than "student" drawing boards, they adjusted in height.

these look like them.

draughtsmen had tall stools to save the effort of getting out of a chair to draw. there were also desks and chairs. writing is easier seated as is calculation.

I have such a table. They are available in the used office furniture market.
