Usage
Saddles may be used to ride horses, donkeys, mules, pigs and striders.An equine mob equipped with saddle is rendered wearing a bridle along with the saddle.

a saddle on a pig equips the pig with the saddle, allowing the player to ride the pig. Controlling the pig requires using a carrot on a stick. Killing the pig is the only way to retrieve the saddle. Striders behave in a similar manner when equipped with a saddle, but require a warped fungus on a stick to be controlled instead.

Tamed horses, donkeys, and mules can be ridden without a saddle, but a saddle is required to control them. Once tamed, they can be equipped with a saddle by placing it in their inventory, which can be opened by pressing while holding a saddle or. The saddle can be unequipped by removing it from the specific inventory slot.

Trivia

 * A saddle is considered "armor" by the game, but the value of protection to the pig is zero.
 * A saddle can still be seen if the pig is invisible.
 * Punching a pig or horse while holding a saddle causes the mob to wear the saddle, and it is removed from the player's inventory, even in Creative mode.
 * The "When Pigs Fly" achievement requires "Cow Tipper" even though leather is not used to craft saddles.
