Too hard and dense: it has more give if you put your hand on it, but once you lay on it, all of that just disappears and it's like laying on a board: I got someone else to try it too and they agreed. I've slept on it for just two nights and have not had anywhere near a good night's sleep. My previous mattress was a memory foam too, but I really don't like this one. Also it is not cooling at all, in fact I would say the dead opposite.
