A container having deployable support surfaces for reinforcing the container to permit stacking is disclosed. The container includes a plurality of sidewalls pivotably attached to one another end to end. A bottom flap is attached to the bottom edge of each sidewall, and a pivotable support surface is attached to the top edges of two oppositely disposed sidewalls. For each support surface, a support panel extends from the support surface to the bottom flap directly beneath it. The support panels are pivotably attached to the support surfaces and bottom flaps, and, with the oppositely disposed side walls, act as a four bar mechanism to position the support surfaces substantially perpendicular to the side walls when the bottom flaps are pivoted to form the bottom of the container.
