A modular seat assembly includes a seat frame, a modular seat component for engaging the seat frame including a mounting bracket, a cable routed towards the frame and engaged with the mounting bracket, and a cable tensioning system. The cable tensioning system is configured to tighten the cable into a tensioned state and release the cable into a slacked state. In the tensioned state, the modular seat component is secured to the seat frame via engagement of the cable with the mounting bracket, and in the slacked state, the modular seat component is releasable from the cable via disengagement of the cable from the respective mounting bracket.
