Claims (15)

A heat generating member including a heating element;
An elastic body unit device formed by enclosing a pedestal part and a plurality of columnar heat conductive elastic members discretely arranged on the pedestal part with a bag, and disposed on the heat generating member;
With
A mattress device in which the heat generating members are arranged in a sparsely arranged manner so that a foot side is dense with respect to a sleeping person's head side .   2. The mattress device according to claim 1, wherein the heat generating member applies a temperature to the elastic unit device with a temperature gradient that increases a temperature of a sleeping person's foot.   The mattress device according to claim 1, wherein the elastic body unit device is divided into a plurality of unit elastic body units in the longitudinal direction. The mattress device according to claim 1, wherein the elastic body unit device is divided into a plurality of unit elastic body units in the lateral direction.   The mattress device according to claim 1, wherein the columnar heat conductive elastic member is made of an elastomer resin.   The mattress device according to claim 1, wherein each of the columnar heat conductive elastic members is provided integrally with the pedestal portion.   The mattress device according to claim 1, wherein the bag is made of an elastically deformable material.   The mattress device according to claim 1, wherein the heating element is a heater wire.   A heater wire extending in a zigzag shape along the longitudinal direction of the elastic body unit device is adopted as the heating element, and the density is adjusted by a folding density per unit length along the longitudinal direction of the elastic body unit device. The mattress device according to claim 1.   The mattress device according to claim 1, wherein the heating element is appropriately controlled intermittently by a timer. The heating element is disposed in a recessed portion formed in the main body, and the dense state of the heating element is disposed so as to be denser in the order of a central part, a head part, and a foot part for a sleeping person. The mattress device according to claim 1 . A base formed with an upwardly open recess;
A heating member that encloses the heating elements arranged in a dense manner, and is fitted in the recess;
An elastic body unit device having a pedestal part and a plurality of columnar heat transfer elastic members discretely disposed on the pedestal part, and fitted in the recess to be placed on the heat generating member;
A mattress device comprising: The mattress device according to claim 12, further comprising: a urethane resin quilt member that is placed on an upper surface of the base and covers the opening of the recess; and a cover that includes the base and the urethane resin quilt member.   The mattress device according to claim 12, wherein the heating element is a heater wire.   A heater wire extending in a zigzag shape along the longitudinal direction of the elastic body unit device is adopted as the heating element, and the density is adjusted by a folding density per unit length along the longitudinal direction of the elastic body unit device. The mattress device according to claim 12, wherein:
