Abstract: A mattress in which a vibration is unlikely to be transmitted between different cushion members is provided. The mattress includes a mattress cushion on which a plurality of persons can lie in a left/right direction, the mattress cushion includes a plurality of cushion members that can be separated in the left/right direction, each of the cushion members is formed with a filament three-dimensional bonded member that includes a plurality of filaments, and includes a contact surface that is in contact with another cushion member adjacent to the cushion member and ends of the filaments of the cushion member do not enter the other cushion member adjacent to the cushion member.

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.
