Armor Stand

Armor Stands are entities that are able to hold and display armor, mob heads, and pumpkins.

Usage
Armor stands are able to hold armor of different materials, as well as mob heads and pumpkins. The stand does not have a GUI, players interact with it directly. They are also able to be placed in different orientations, similar to banners or signs. Armor stands are entities and they can be pushed by pistons, transported by minecarts and bounced by slime blocks. An armor stand can be broken by double-clicking with the left mouse button.

It is possible to summon an armor stand using commands.
 * spawns an armor stand with arms
 * spawns a smaller armor stand.

Properties
Armor stands are not damaged by cactus, fire or lava although they do catch fire. If an armor stand is blown up by TNT, it will break and not drop as an item. Any armor on the stand will drop when the stand is broken. Armor can be automatically placed on armor stands with a dispenser, but mob heads can only be added manually. Because armor stands are entities, they obey gravity (unless specially spawned without gravity), allowing then to fall and rest on non-full blocks such as Enchanting Tables and Snow Cover.

Trivia

 * Although the slab in the crafting recipe can be any stone-type slab, it will not accept red sandstone slabs, because red sandstone slabs use a different ID to other stone-type slabs.
