To provide a cushion structure that has a three-dimensionally multi-layered fiber structure, thus has excellent cushioning property without side slipping and stable compression recovery.
The ground weaves 10 made of plain weave are vertically piled up in the warp direction and many of the high shrinkage yarns 11 are confounded and the ground weaves 10 are bent to wave form. By bending the ground weave 10 into wave like form, a plurality of continuous spaces 12 are arranged in the weft direction and the layer structure M is formed. In the layer structure M, the warp yarns 10a made of flat monofilaments are confounded with upper and lower high shrinkage yarns 11 to maintain the interval whereby the continuous spaces 12 are retained and the warp 10a supports the frame skeleton of the continuous gap space. And, the weft yarns 10b constituting the ground weaves 10 are incorporated into the warp thereby the total warps 10a are unified.
