PROBLEM TO BE SOLVED: To provide a bed cushion device capable of providing a comfortable touch with no oppressive feeling by buckling in being pressed and distributing a load along the physique in a surface supporting the body of a user. SOLUTION: This bed cushion device has a three-layer structure of an upper part elastic layer, an intermediate elastic layer, a lower part elastic layer and an exterior body covering over the three layers, the upper part elastic layer is formed of a plate-shape low repulsive elastic material, the intermediate elastic layer is formed of a cushion core whose thin-wall partition is formed into a grid by an elastic material, and the lower part elastic layer is formed of a spring unit having a repulsive force higher than that of the intermediate elastic layer. This bed cushion device is so constituted that the partition of the cushion core is composed of elastomer with a hardness of shore A10-40 and resilience reinforcing agent is mixed in the elastomer.
