Today it just got taken out of the box,I was amazed to see that it didn't even look like it had been in a box.i left it on the bed for 8 hrs before I layed down to take a nap, usually it takes me time to fall asleep.but this mattress is very comfortable and I fell asleep right away.when I got up I didnt feel any pain in my back Ithat i was getting from my old mattress that was a pillow top.excellent i say excellant!!
