A vehicle includes a convertible space system that is integrated into a floor of an interior cargo area. The convertible space system includes a pair of panels that are moveable between a stowed position and a deployed position. When in the deployed position, the pair of panels are extended and integrally positioned on the floor to define a primary load bearing surface. When in the stowed position, the pair of panels are collapsed and positioned on the floor to define vertically extending lateral boundary walls for the cargo area, and to expose a secondary load bearing surface disposed below the primary load bearing surface, thereby increasing the effective height of the interior cargo area.
