It’s only been one night however, it was the best night my lower back has ever had lol. If you’re someone who struggles with herniated discs or any back paindiscomfort while sleeping, this is the mattress for you. I always slunk onto my boyfriends side of the bed (simply because he is bigger), which hurt my back immensely due to my herniated discs and laboring job. With this mattress that did not happen!! I’m a very light sleeper and I didn’t even feel him get into the bed. One thing many reviewers didn’t seem to realize is that this mattress needs time to “breathe” and plump. It is rolled up in a “ball” in a box for god knows how long so of course when you first open it it appears uneven and thin. If you give it time to do what it’s supposed to do on its own you will not be unhappy. I would give it more stars if possible. I’ll update after a longer period of time using it!
