This mattress has the possible potential of being very comfortable. Unfortunately,  mine is defective and one side dips so much it is to uncomfortable to lay on it. I tried to return it the day after I  received it. I was asked to send pictures, which I explained wouldn't help, as it is not a visual defect; you must lay on it and feel it. I was also told that I couldn't return it because it was no longer in its original box; which was due to the delivery men removing it from the box white it was still in their truck. I've sent pictures, as I may get another one through the 100 day mattress warranty.
