From the static component P of the mattress internal pressure, a fluctuation part ?V of the mattress internal pressure depending on the value is specified (S 12). Each value of the fluctuation part ?V of the mattress internal pressure is obtained beforehand by applying a predetermined load, and changing the static component P of the mattress internal pressure.
