This resource pack includes 5 types, 16 colors chairs. Each chair can be rotated 45 degrees.

This pack uses the Wheat Seeds System. Each chair is actually a wheat seeds item in an invisible item frame which put on an invisible barrier block. So if you use some plugin to sit on blocks (for example GSit), you can sit on a chair.
