Very soft. I bought it because it supposedly has an innerspring, which many of these mattress-in-a-box products don't. I sat on the edge and it completely collapsed-no support there at all. Any one who moves in bed toward the edge may find themselves on the floor. I weigh 160 pounds and when I laid on it, I sank a good 2 inches into the mattress. It looks good but I am disappointed. It is for my guest room futon/couch so I will keep it, but I was hoping for something more comfortable than the very hard futon mattress that is on there now. This is the opposite, dang!
