Used for a guest room. Very comfortable rest. Medium Firm. You will not be able to sit stable on the edge of this bed though and will slide off. And it is not quite 10 inches either it is more like 9 inches, even after the initial 3 days to air out. But it will be one of the most comfortable sleep ever. No chemicals smell. Super ridiculous fast delivery that I could not change to pay a little more for the extras in the bundle.
