I would not say this is a Medium Firm mattress, this was very soft, too soft, we had to return it. On a positive side, the return process was fairly easy and they were extremely helpful.

My daughter is super picky about her matresses. She doesn't like full memory foam, but I needed one that could be shipped to my door. This was a good compromise, and she LOVES it. Its super heavy, so be prepared when it comes

The best mattress ever! I brought this for my mother and she absolutely loves it! It’s firm and gives in all the right places. Honestly it’s better than my $5k TemperPedic!

So far so good. I bought a twin size supper plus for my 7 year old and we love it! I thought that a mattress inside a box wasn't good but this passed my expectations

I ordered a full size mattress. The mattress I received is a full 3 1/2 inches wider than either of my full size beds and much smaller that my queen bed. Being to wide causes the mattress to collapse along the edge.

I bought this for a Murphy bed that I made and after guests used it they gave me great feedback and said it was very comfortable. Easy setup too. Just open it and let it expand for a day.

Although the mattress is advertised as 12 inches, mine has only reached 10.5 inches and it's been 5 days. Other than that I do feel like it's super comfy! But since it's not expanded fully it's not sitting on my box spring correctly

Amazing how these things expand once opened. Softer mattress for my liking and contours to your body. We use them for guests and the grandchildren love them.

The package arrived 3 days early to our surprise. The setup was so easy and the mattress has been so far better than expected. The firmness is just right and no more aching back in the morning. Very happy with this product.

This was not as firm as I suspected. I put this mattress on a good firm box spring. The sides of this mattress feel kind of weak but the middle is very comfortable. It did not have sides handles which woul have made it easier to move.
