Sit (Fabric)

Sit provides players with the ability to use slabs and stairs as seating. Simply right-click on the top surface of a slab or stair block while holding an empty hand to sit on it. To exit, use the key you normally use to exit a minecart (by default SHIFT). In most cases, slabs and stairs from other mods are supported.

The mod works in both singleplayer and multiplayer modes, but for it to function on a server, it must be installed on both the client and server sides.

You are free to include this mod in any modpacks.
