Hi Peterpan1121,
Unless you can find out the information in this article about the materials inside the mattress … it’s not possible for me to make any meaningful comments but like all the major brands Simmons tends to use lower quality materials in the comfort layers of their mattresses.

These specs are also incomplete and don’t include information about all the layers but as you can see in the guidelines here … just the top 2.5" is lower density memory foam than I would be comfortable with and would be a weak link in the mattress. I would pass it by.
