PROBLEM TO BE SOLVED: To obtain soft seating feeling without inhibiting deformation to a specific direction by facilitating deformation of a filament body itself constructing a substrate, and make load support excellent while suppressing a thickness of the substrate, in a substrate structure of a load support member which contacts a seated person on a chair and receives a load.SOLUTION: A backrest substrate 21 has a shape where a central part in a width direction in the surface direction is bent or curved so as to project to the opposite seated person side to both ends in the width direction. Each of filament bodies 88 constructing the backrest substrate 21 extends to the height direction in the surface direction without crossing the other filament body 88. An intermediate part in the height direction is curved or bent so as to project to the central side in the width direction than both ends in the height direction, and the bent shapes or curved shapes of the plurality of filament bodies 88 are symmetrical while interposing a width direction center line CL of the backrest substrate 21. 【課題】椅子における着座者と接して荷重を受ける荷重支持部材の基板構造において、基板を構成する線条体自体を変形し易くして特定方向への変形が阻害されない柔軟な着座感を得るとともに、基板の厚さを抑えた上で荷重支持を良好にする。【解決手段】背凭れ基板２１は、その面方向の内の幅方向における中央部が、該幅方向の両端部に対して反着座者側へ突出するように屈曲又は湾曲した形状であり、背凭れ基板２１を構成する複数の線条体８８のそれぞれは、他の線条体８８と交差することなく前記面方向の内の高さ方向に延び、かつ前記高さ方向の中間部が該高さ方向の両端部よりも前記幅方向の中央側に突出するように湾曲又は屈曲し、複数の線条体８８の屈曲形状又は湾曲形状は、背凭れ基板２１の幅方向中心線ＣＬを挟んで対称をなす。【選択図】図１１
