It is not a machine since a simple version of an ordinary chair does not have any moving parts and does not convert energy. It is best classified as a tool and it would be related to an inclined plane. A modern office chair would be composed of several more complex tools. If you consider the rollers on the legs, they would be wheels. If you want to use your imagination they are related to Roman chariots, horse-drawn carriage, or even the modern car as a distant relative.
Energy is actually most evident when there is work. When an object or person moves it creates energy. An example of this would be pedaling a bicycle.

I think people strapped the person who was being accused to a chair. Then, the people who were accusing the "witch" would put the chair underwater for long periods of time. Then the chair would be brought up from the water. If the "witch" was dead, then it would turn out that the person wasn't a witch. If the person survived, he/she would probably be hanged or stoned to death because they were a witch and did witchcraft. If you look up "Salem Witchcraft" or something like that, I'm sure you'll find something. Hope this helped!
