A contoured seat for airplanes and automobiles comprising a bottom portion and a back portion, both supported by a basic frame support. The bottom portion comprises a bottom cushion and a bottom support. The cusion has a front edge, two thigh portions, a center ridge, a fundament section, two side portions, and a rear fundament section, all conforming to the passenger\s shape. Preferably, the cushion also contains a plurality of identations. The thigh portions and the fundament section are depressed below the surrounding surfaces. The back portion, which surrounds the frame support, has two lower side portions, a lower central plane portion, a lower middle central portion, and an upper middle central portion. The side portions extend to support the hip. The lower central plane portion extends to support the user\s extreme lower back as does the upper lower central plane portion. The lower middle central plane portion is concave and the upper middle central section is convex to provide a form fitting support for the user\s vertebral column. The support itself is contoured and preferable contains a plurality of holes. Between the support and the back portion in the area of the upper lower central plane portion is preferably placed memory material to provide further support and comfort.
