Coming from an old sleep number mattress, this thing is practically magic.  I became so used to trying to sleep on a stifling, glorified airbag that I had no idea just how much of an upgrade this would be until I got to experience it for a couple nights.  No more midnight sweat episodes!  No more leaky airbags!  No more uneven sleeping surfaces!  I sleep so well on this thing that when I wake up in the morning, my facial hair is all pushed over to one side of my face, because I no longer toss and turn throughout the night.  In case you couldn't tell, I'm very enthusiastic about just how great this mattress is.
