Brand with Most Comfortable Bed?

Marriott beds are 30% off on the Bonvoy website as of today. Thinking of purchasing one and need some perpective from the community. What Marriott brand hotel has the most comfortable beds in your opinion. Is there a Marriott bed that you actually look forward to when traveling? Why so?

Personally, I am not fan of sinking into 8 inches of memory foam. I like a fairly firm base but soft-ish top. Looking forward to hearing your experiences. Thanks, everyone.
