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 three hours at a time, nor does it alleviate tiredness. Any attempt to sleep beyond the three hour limit may result in the contraction of an illness.
