On a firmness scale this mattress is about a 7 out of 10, with 10 being extra firm. The 1.5 inches of foam on top allow you sleep comfortably in any position, while the latex underneath still provides great back support. As a result, you don't get the feeling of sinking into the bed as with some other foam mattresses. The mattress came packaged in a roll and was usable the same day with no noticeable smell. Overall, I am very happy with my purchase and would highly recommend this mattress to anyone looking for good value in a latex foam mattress.
