To obtain a to obtain a cushion function and suitable sound effects and a sound pressure effect by containing a speaker without giving sense of incongruity and avoiding impact from an outside to the speaker at the same time. A cushion 20 comprising: a resin body with a spring structure 10 comprising a three-dimensional structure including voids at a predetermined bulk density, the three-dimensional structure being obtained by contacting, entwining, and gathering adjacent ones of random loops or curls of continuous filaments made from a thermoplastic resin in such a manner as to allow the resulting structure to have a layered structure in which oppositely lengthwise disposed superficial layers have a high bulk density, and a core layer having a low bulk density is interposed between the superficial layers, wherein the resin body with the spring structure supports at least an upper half of a human body when using the cushion; and a speaker incorporated in the resin body with the spring structure 10 or oppositely disposed on either of the superficial layers of the resin body with the spring structure 10.
