Its firm, almost too firm was my first impression of this mattress, but after sleeping on this for a few weeks now Ive grown to love it! I get a good nights sleep and my body doesn’t have any aches or pains from sleeping awkwardly unlike my last mattress. I also don’t get overly hot. It’s gorgeous, good quality and I love the All over black color of it. 

As for the height reference I have a platform bed which is about 8 to 10 inches off the ground and the mattress is about 15 inches. I’m 5 feet and it sits mid thigh when I stand next to it.
