The short version of our full methodology: MattressNut verdicts come from materials-and-construction analysis, spec verification against official brand pages, and pattern analysis of verified owner reviews at scale. We don't run a physical lab, and we don't pretend to.
What that means in practice
- Materials first. Foam density, coil gauge, latex type — the build determines how a mattress ages, and the build is verifiable.
- Every number sourced. Prices, trials, and warranties are checked against the brand's official page at the time of writing.
- Owners as the dataset. Thousands of verified purchase reviews, read for patterns — not cherry-picked quotes.
- Same criteria everywhere. Recommendations follow identical rules on every page; sponsored placements are labeled.
Questions about a specific verdict? Every review states what it's based on — and when something is an owner-reported pattern rather than a verifiable spec, we say so inline.
