A seat structure consisting of a seat cushion unit and a seat back unit wherein each of said units comprises a foam body and a spring assembly embedded in the body. The seating units are mounted on a frame and each spring assembly includes a plurality of spaced linear springs which project from the foam body and are attached to the frame so as to mount the seating unit on the frame. In the seating cushion unit, the linear springs, border wire and bolster wires cooperate to provide desired seating resilience and the spring end portions are snapped over upstruck tabs formed on the frame. In the seating back unit, the spring end portions extend through mounting slots in the frame. In both units, the springs are connected by bolster wires and the foam bodies are formed with grooves aligned with the bolster wires to enable mounting of the seat structure covering on the foam bodies by attachment to the bolster wires.
