Feels like a medium firmness to me, much softer than what I am used to sleeping on, which is a cotton futon on a platform, no springs no faam, so this is very different. My legs ,ankles and feet appreciate the floating sensation of the new bedding.  This is my first night to use, so will probably feel great tomorrow. I will say that there is no odor from this packaging or product, that it expanded to full size in about 3 hrs. I am happy that it has a washable cover and looks like a real mattress.
