You can see some similar comments that talk about the difference between the feel and performance of a separate topper and having the same layers inside the mattress in posts #3 and #4 here and in this topic (just to let you know that it’s not just your imagination :))
This also isn’t an unusual comment and there are many people who either “need” or prefer a thicker mattress. You can read a little more about the effects of thicker layers or a thicker mattress in post #14 here. Some people would feel this and some wouldn’t but it would depend on the person and on the specifics of the layers.
I certainly agree … and I only wish this was more common in the industry
