Abstract: A mattress according to the invention is formed from a plurality of layers stacked in a thickness direction thereof, and includes a tactile layer that is positioned on an upper side in use, and a cushion layer that is positioned on a lower side in use. The tactile layer and the cushion layer each contain an elastic body constituted of a filament three-dimensional assembly. The elastic body contained in the cushion layer has a larger resiliency than that of the elastic body contained in the tactile layer, and is 100 N or more and 200 N or less. The elastic body contained in the tactile layer has a resiliency of 10 N or more and 80 N or less. The tactile layer shows a constant sinking displacement regardless of load.

Abstract: A mattress core material includes a plurality of flat cushion bodies stacked in a thickness direction thereof, including at least a first cushion body which becomes an upper part; and a second cushion body which becomes a lower part, the first and second cushion bodies including a three-dimensional filaments-linked structure, each including a high-density upper surface layer having high filament density; a high-density lower surface layer having high filament density; and a low-density elastic layer, a high-density intermediate layer being formed in an intermediate position in the thickness direction of the mattress core material in which the first and second cushion bodies are stacked as upper and lower parts in the thickness direction, respectively, the high-density intermediate layer having a function of distributing a vertically applied compressive stress, along a curvature of an interface between the first and second cushion bodies in the high-density intermediate layer.
