A system for reversibly dividing a space is disclosed. A first panel consists of a first vertical member and a first horizontal member attached perpendicular to a bottom end of the first vertical member and extends away from the first vertical member towards a second panel. The second panel consists of a second vertical member and a second horizontal member attached perpendicular to a top end of the second vertical member and extends away from the second vertical member towards the first panel. The first and second panel can be stored in an overhead position. The space is reversibly divided when the first panel and the second panel are lowered. The first panel is lowered such that the first panel forms a top portion of a wall. The second panel is lowered until the second horizontal member rests on the first horizontal member, forming a bottom portion of the wall.
