1. An apparatus for selecting a mattress which will be suitable for the anatomy of a user, comprising:

  • a measuring mattress having a predetermined hardness, on which the user lies;

    detecting means for detecting a load on each of a plurality of points of the measuring mattress when the user lies on the measuring mattress;

    said detecting means including means for generating a detection signal indicating the load at each of the plurality of points, the load at each of the plurality of points deforming the measuring mattress by an amount determined by the actual load at each respective point;

    control means for receiving the detection signal generated by said detecting means and for calculating a first average value that represents a plurality of deformations in the measuring mattress at a head portion and a leg portion of the user, said control means further calculating a second average value that represents a plurality of deformations in the measuring mattress at a plurality of other portions of the user excluding the head portion and the leg portion of the user; and

    display means for displaying the first average value and the second average value calculated by said control means as a first straight line and a second straight line, respectively, said display means further displaying a mark which designates a hardness of a mattress suitable for the user, said hardness being determined on the basis of a comparison in the amounts of deformation represented by the first and second straight lines.
