At dusk or night, the item can be used by dragging and dropping on a character (which causes the 'Sleep' option to appear) or by right-clicking them from the inventory. The character will place it on the ground and lie down, and time will advance to the beginning of the next day. When going to sleep in a bed roll, the character takes an immediate hunger penalty. If the hunger penalty causes hunger to reduce to 0, the character will lose health in their sleep. Considering that this item allows a player to skip the dusk/night sanity loss, this makes the bed roll's sanity benefits even more pronounced.
Bed rolls cannot be used in "dangerous" situations, such as near a Spider Nest, in a Marsh (if Tentacles are nearby, as any Tentacles count as dangerous mobs even if they're under the surface), during combat, when monsters are nearby, or when Hounds or Depths Worms are approaching. However, they can be used when under attack by Shadow Creatures.
Bed Rolls are unusable by Wickerbottom due to her insomnia.
The Fur Roll can be used three times. Using it restores 50 Sanity and 30 Health but consumes 75 hunger. Additionally, it will set the user's temperature to maximum, which is useful during winter.
In the Reign of Giants DLC, the behavior changes so that upon the Fur Roll's use, if the sleeper's temperature is below 35, it will be set to 35, but if it is above 52.5, it will increase by 17.5, making it dangerous to use in the heat of Summer when overheating is a possibility.
The Straw Roll will not affect the sleeper's temperature.
Don't Starve TogetherEdit
In Don't Starve Together, sleeping in a Bed Roll affects stats over time rather than instantly, and sleeping won't skip time. If Hunger reaches 0, the character will automatically wake up to avoid starvation.
Using the Straw Roll restores 0.67 Sanity/second, and costs 1 Hunger/second.
Using the Fur Roll restores 1 Sanity/second, 1 Health/second, and costs 1 Hunger/second. Additionally, it will increase the user's temperature by 1/second if it is less than 30, and decrease the user's temperature by 1/second if it is greater than 45.
The Fur Roll will not prevent the user's temperature from being affected by other sources, so its temperature effect may be counteracted, and will also stack with other sources.
- The Straw Roll was added in the October 2, 2012 update, and the Fur Roll was added in the Underground update.
- Using a straw roll and then immediately examining it will cause the character to just lie on the mat, instead of sleeping.
- By using a Straw/Fur Roll right before daytime, but still before the next day, you can skip 'two' days (the day counter skips a day, e.g.: goes from day 7 to day 9).
