Automatic adaptive comfort for bunk mattress

A vehicle, comprising:

• a bunk, in particular for a vehicle cabin, comprising:
• a base plate;
• an upper layer;
• a plurality of supporting members which are vertically compressible, such as springs, the supporting members being arranged spaced apart from one another, according to an array, substantially over a whole surface of the bunk;
• a plurality of pressure sensors which are part of the upper layer and arranged in an adaptable area comprising at least one area of the bunk;
• a moving mechanism connected to at least some of the supporting members located in the adaptable area, configured to move the supporting members with respect to and parallel to the base plate;
• and
• a control unit connected to the pressure sensors and to the moving mechanism, the control unit being configured to cause the moving mechanism to automatically and dynamically move the supporting members in the adaptable area, as a function of current pressure data provided by the pressure sensors, so as to locally change the density of the supporting members in order to provide a locally variable bunk firmness.
