Overall, I'm pleasantly surprised with how comfortable this mattress is.  It did not have a pillow top, yet there was a plushness to it that made it feel like it was a pillow top.  The overall size of the mattress is very tall, but it still fit our deep fitted sheets and mattress pad we already had.  I do not awaken in the night when my partner moves around, nor vice versa.  My only complaint would be the sides could use more support so if you sit on the site of the bed, it won't sink in as much.  It keeps me cool at night, and doesn't seem to radiate heat as much as my old mattress.  There also didn't seem to be an odor with this mattress as there have been with other new mattresses I've purchased in the past.   I no longer wake up feeling sore and tired.
