Tired of standing all the time? Built a house and now you need a break? Then take a seat!
Benches is a plugin that allows you to right click on stairs and sit down. You are sitting like you would be if you were sitting in a boat or minecart and you can exit by pressing shift. Only one person is allowed to sit in a chair at a time. You can configure the plugin to auto orient the player and whether or not benches require signs on the side.
Configuration
Signs: Whether or not benches should require signs on the side of them to function.
Rotate: When the player sits down should they be rotated to face forward on the chair.

This bench is one that requires signs on the side. The bench can be however wide you want it to be even if signs are enabled.
