A vehicle seating assembly includes a seat frame disposed between an integrally formed back panel and an inner close-out panel. A cushion assembly is operably coupled to the inner close-out panel. A composite support member is substantially encompassed by the cushion assembly. The composite support member includes attachment members projecting rearwardly from inside the cushion assembly that engage with the inner close-out panel. The attachment members include snap-fit features disposed at a lower portion of the composite support member. Retaining rings are disposed at an upper portion of the composite support member. An upper trim piece extends over a top portion of the seat frame, the back panel, and the inner close-out panel.
