We ordered 4 of these mattresses.  2 twin, a King and Queen.  We were so impressed with the Lucid foam mattresses. We followed the directions as suggested upon arrival.  All mattresses arrived rolled up in a box.  When delivered, it was well protected in plastic, but the boxes were destroyed.  The queen and Kong mattresses were heavy to carry.  You will need help.  Very comfortable!  A little more firm than I expected, but as a side sleeper, I slept very well.  I might write more about this a little later since we just received these.
