This is Roll Bottom, a desk design by Ian Stell. The metal secretary desk cover slides down and forms the seat. I'm not sure if it's practical, but it's pretty. You could give it to a coworker that you dislike.

Does it even function? They never sit in the seat? Sure it's fun to watch the lid go on the track but if they can't sit in it what good is it?
