To provide a vehicular seat base material which is lightweight, has excellent cushion property, and is excellent in adhesion between the cushion material and the vehicular seat base material, and a vehicular seat using the vehicular seat base material.SOLUTION: In a vehicular seat 10 where a cushion material 21 is laminated on a vehicular seat base material 11, a vehicular seat base material 11 is composed of a flexible urethane foam of 30 to 70 kg/m3 density (following JIS K 7222). Rigidity of the flexible urethane foam composing the vehicular seat base material 11 is preferably equal to or larger than 25 and below 100 N during 2% compression, is equal to or larger than 45 to below 200 N during 5% compression, and is equal to or larger than 65 and below 300 N during 10% compression.SELECTED DRAWING: Figure 1
【課題】軽量でクッション性が良好であり、かつクッション材と車両用シート基材との接着性が良好な車両用シート基材と、その車両用シート基材を用いる車両用シートを提供する。【解決手段】車両用シート基材11にクッション材21が積層された車両用シート10において、車両用シート基材11を、密度(JIS K 7222準拠)30〜70kg/m3の軟質ウレタンフォームで構成した。車両用シート基材11を構成する軟質ウレタンフォームの硬さは、2%圧縮硬さが25〜100N未満、5%圧縮時の硬さが45〜200N未満、10%圧縮時の硬さが65〜300N未満であるのが好ましい。【選択図】図1
