I like the functionality of this mattress.  It is a good pick for a guest room and feels fine on the floor, too.  It is light enough for me to pick up and tote around, even though it is thicker and somewhat bulky.  The mattress had a bit of a chemically smell when we took it out of the packaging, so we aired it out before bringing it into the house.  Overall, a solid mattress, especially for a trifold.
