I received this mattress in exchange for my opinion and as hard as it is to say this, I am not at all satisfied with it and if I had purchased it, I would have promptly returned it. The sides have no support so unless you’re right in the middle of the bed you roll right off. I received this mattress at the end of September and by mid November there is a permanent “dip” where my bottom rests and it’s very uncomfortable. I will be replacing this just as soon as I am can, being disabled I unfortunately spend a lot of time in bed so I can definitely say that this is not a quality mattress. It might be okay if you have kids or for a spare bedroom you don’t use often. I appreciate the opportunity to try it out and I wish it was more supportive.
