I would use at least two 2x6 nailed together for horizontal members. Vertical columns at the quarter spans. With cross bracing at ever corner. Then sheeted with 3/4" plywood. If I was doing it I would use two 2x8's nailed together. I will also third the checking of the floor for capacity. I would be more likely to say if it is not on a concrete slab then don't do it.
