Bed

Beds are an object and item that appear in The Legend of Zelda series. They are beds which Link can sleep in to restore hearts and/or pass the time.

The Legend of Zelda: Skyward Sword
Beds appear primarily in The Sky and can be slept in order to restore hearts or change the time of day. Link has his own bed in his room at the Knight Academy, though humorously he can sleep in other people's beds, even Zelda's bed in Zelda's Room once he has managed to sneak inside and unlock the door.

Beedle's Air Shop has a bed inside and Link can sleep in it to visit Beedle's Island at night. Additionally the beds in the Lumpy Pumpkin can be used to visit Pumpkin Landing. As a result, they allow Link to visit other areas in the sky besides Skyloft at night as he is unable to fly his Loftwing at night.

The Legend of Zelda: Ocarina of Time 3D
In the 3DS remake of Ocarina of Time, Link can sleep in his bed in Link's House to restore health. It also allows him to battle bosses he has previously defeated.

The Legend of Zelda: Breath of the Wild
Beds can be found mainly at Inns, Stables, the Woodcutter's House, Selmie's Spot, Pondo's Lodge, and Link's House. Like Campfires and Cooking Pots, they can be used to pass the time to morning, noon, or night. However unlike Campfires, sleeping in a bed restores Heart Containers. Some inns even off special beds or additional services that add temporary yellow hearts or a yellow stamina wheel though cost more than the standard bed. While most inns require Link to pay to sleep the Deku Tree's Navel Inn in Korok Forest allows Link to sleep for free due to the bed in the inn being made especially for him to sleep in due to his heroic status.
