A Sleeping Bag is a portable bed in Stranded Deep. It could be considered a direct upgrade to the Shelter, since it bears the same functionality. When dropped on a Raft, it severely weighs it down, and if you are using the Life Raft, it may even sink it. You cannot, however, sleep or save on raft in the middle of the sea. That's why it's best to store it in equipment wheel or a crate. To use it, drop it down on the ground.
Notes
- You can sleep only between 6pm-6am.
- In latest updates, it is called simply a "Bed" in the crafting menu.
