Our Medley organic latex mattress was shipped in a box. The mattress was very tightly rolled. The box measured about 24" x 24"x 48". While it was a compact shipment, which was great, the box is VERY HEAVY. Neither my husband nor I were able to move it alone and we even used a dolly to move it back to the ADU where it lives. Once it's out of the box, you have to unroll the tightly wrapped (with plastic) and then let it expand. The expansion happens very quickly. I think it really took two of us to easily set it up, however, because of its weight.
