One mattress per review. Each is built from every public owner report I could find, scored against the same eight criteria, with the sources linked so you can check the reading rather than take my word for it.
What is in each one
The verdict, and who it is wrong for
Up top, in a sentence. Including the sleeper it does not suit, which is usually the more useful half.
Score by criterion
Eight numbers rather than one, so a mattress that is excellent everywhere except edge support cannot hide behind an average.
The complaint pattern, dated
What people raise, how often, and how long they had owned it when they raised it.
What the paperwork commits to
Trial length, who pays return shipping, the impression depth that triggers a warranty claim, and the exclusions that void it.
