A seat assembly includes a fabric component with a seat surface and with an interior segment directly attached to the fabric component. The interior segment extends from an exterior segment that has a greater flexural resistance than the interior segment.

A vehicle seat that can reduce manufacturing costs while increasing assembling rigidity of an elastic spring for supporting an occupant is described. A vehicle seat includes an elastic spring bridged between a front frame and a rear frame to support an occupant. A hook member is attached to a rear end portion of the elastic spring to be hooked to the rear frame. The hook member includes a hook body extending along an outer periphery of the rear frame and a projection projecting from a front edge of the hook body toward the rear frame and formed to have a width smaller than a width of the hook body. A through-hole is formed in a portion of the hook body, which is opposed to the projection. The through-hole has a width larger than a width of the projection and a length larger than a projecting length of the projection.

A seat assembly includes a base and a support platform spaced above the base. The support platform includes a pad having a hinge portion defining a flex region, wherein the pad is pivotable about the flex region. A link has a lower portion coupled to the base and an upper portion coupled to the pad, wherein the upper portion is pivotable with the pad about the flex region.
