Are counter-height or bar-height straight desks available for standing-only use?

Yes — counter-height straight desks at 36" and standing-height desks at 42" are available for applications where the user stands at the desk rather than sits. These are common in retail, clinical, and laboratory environments. They require a tall drafting stool or standing mat. They do not adjust in height.
