A self-driving office chair

Unlike their reputation, the office worker gets up and moves around a lot. The office worker waits as the coffee machine is brewing, they meet someone and talk for a while, they go to meetings, they hunt down conference rooms in previously unexplored territories. They get lost, and they get tired, and they get bored, and they often forget their laptops on various surfaces where they had to leave it in order to free up both hands.
