Very awesome mattress!  The packaging was amazing.  We have an old home built in the 1930s. with a narrow staircase.  We have always had trouble getting mattresses and large furniture upstairs.  This vacuum sealed mattress was like a dream.  No fuss at all.  We brought the box up very easily unrolled the mattress on the bed frame cut the vacuum seal and voila!  We waited 24 hours to let the bed come to the true 12 inches as described.  Thanks again Wayfair for making our home projects so easy.
