I started this while shopping for a mattress, because I could not find an answer to one question: what does this thing feel like in a year?
The reviews I found came in two kinds. Lab reviews measure a new mattress on a bench: accurate, repeatable, and silent about month fourteen. Affiliate round-ups rank whatever pays best, and you can usually tell within a paragraph. Neither reads the one thing that exists in real quantity — thousands of people describing what happened after they bought.
So that is what this site does. One mattress at a time, every public owner report I can find, sorted and scored the same way each time.
What I am, and what I am not
I am a researcher. There is no test lab here and no showroom, and I have not slept on any of these mattresses. What I can do is read at a scale nobody buying a single mattress has time for, and be exact about what the reports do and do not support.
Where another reviewer has measured something I cannot — density, actual thickness, surface temperature — I cite them by name and link to them. Their work stays on their site.
How it is paid for
Affiliate commissions on some links, and nothing else. No brand has paid for coverage, sent a mattress, or seen a review before it went live. The full disclosure is here.
Corrections
If something here is wrong, or if you are a brand and think a report has been read unfairly, write to me and point at the specific claim. Corrections get made in the open, with a note saying what changed.
