Mattress (Fallout 4)

A mattress is a constructible settlement object and world object in Fallout 4.

Characteristics
Mattresses are dark brown mattresses, which were originally intended to be used on a bed. They can be found in settlements, pre-War buildings, and in makeshift shelters throughout the Commonwealth. They can be used to rest in order to wait for time to pass and/or recover health.

Survival mode
In Survival mode, the mattress can not be slept on for more than five hours at a time, nor can it reduce the sleep-related fatigue state below "Tired." It can prevent the "Tired" state, but only if used before the "Tired" state occurs (14 in-game hours since last sleeping). Any attempt to sleep beyond the five-hour limit is prevented by the game. Like any sleeping in Survival mode, there will be a check for the contraction of an illness. This check is made in the first hour of sleeping and is not increased further by sleeping for longer. Multiple sleep sessions will increase the chance of contracting a disease, but only because additional checks will be made (one per session).

Crafting
The mattress is located under Furniture &#8594; Beds in the workshop.
