Methodology v2.1
How We Test Mattresses
No mattress has completed the current instrumented physical protocol with recorded measurements. Current mattress records are research evaluations, not lab-tested results. Research evaluations compare published manufacturer specifications, construction, materials and buying terms. They are not personally tested results. Third-party claims require attribution; historical experience is not evidence of completion of the current physical protocol. The 9-factor rubric below describes a future physical protocol, not completed tests.
Research first, measurements only with evidence
A precise score is not evidence by itself. We compare materials, construction and buying policies, and explain what those sources cannot establish about your experience.
No mattress has completed the current instrumented physical protocol with recorded measurements. Current mattress records are research evaluations, not lab-tested results. Personally tested observations need dated product-specific records. Manufacturer and third-party specifications remain attributed claims, not our own measurements; historical accounts do not prove completion of this protocol.
Our proposed scoring formulas are public. They describe how future recorded inputs would be converted into scores. They do not validate legacy ratings or establish measured performance today.
The 9 Future Physical-Scoring Factors
The proposed weights total 100%. No completed test dataset validates these thresholds. The rubric is separate from current written research evaluations.
Context outside the future score
These topics can inform a research comparison, but there are no current instrumented results to report. Future measurements would need their own evidence and conditions.
- Sinkage. Compression can describe feel, but cannot be inferred as a measured value from material specifications alone.
- Bounce. Material responsiveness can be discussed qualitatively; a rebound percentage would require a documented physical test.
- Cover composition. Use manufacturer-reported fiber content where sourced; it does not establish a measured durability or lifespan.

Errors & corrections policy
Our policy is to correct factual errors and explain material changes. Documented manufacturer updates prompt a review of the affected research; they do not imply a physical retest. Record real content changes rather than refreshing dates automatically.
Spotted something that looks wrong? Send the source and affected page. No fixed response-time commitment is documented. Prices on record can change; confirm the seller's current price, configuration and terms. No weekly price-verification cadence is established here.
