I have been sleeping on this mattress daily for the past 2 months. For the first month the mattress never lost air at night. Now I have to pump it up before I go to bed EVERY single night and it is losing more and more air. Also, I sat down on it to go to bed and I heard a pop. Not sure what they are called but the seams that hold the air in different compartments broke and they are blown out. More popped this week. Now my mattress has a giant bump. Very disappointed. Other than those issues it was very comfortable. Wish it would have lasted more than a month though.
