Editorial Guidelines & Review Integrity
How we weight sensor readings, audit brand specifications, and preserve 100% commercial independence.
1. Editorial Independence & Firewall Policy
Our editorial testing division operates behind a strict commercial firewall from advertising and affiliate partnerships at Tested Mattress Media LLC. Mattress manufacturers cannot pay to increase a rating, suppress a criticism, preview scores prior to publication, or buy placement in our Best Mattress rankings.
No sponsored brand placements exist inside our scorecard tables. When we receive media sample units for new-release coverage, they undergo the identical instrumented protocol as anonymously purchased retail beds—and brands are notified that low pressure or thermal results will be published unchanged.
2. Transparent Lab Scoring Rubric (10.0 Scale)
Overall mattress scores on testedmattress.com are computed using a weighted composite of six standardized test categories:
| Testing Category | Weight | Primary Lab Instrument |
|---|---|---|
| Pressure Relief & Spinal Alignment | 25% | 1,024-sensor tactile pressure pad (mmHg) across 3 sleep positions |
| Cooling & Thermal Regulation | 20% | FLIR infrared thermography over 60-minute load + 5-min recovery |
| Motion Isolation | 15% | Tri-axial seismometer & weighted impact drop test |
| Edge Support & Perimeter Stability | 15% | Calibrated 175-lb & 230-lb edge deflection depth gauge |
| Responsiveness & Ease of Movement | 10% | Steel-ball rebound height + millisecond foam recovery timer |
| Material Durability & Construction | 15% | Foam PCF/ILD verification, coil gauge caliper & warranty audit |
3. Five-Step Review & Fact-Checking Lifecycle
- Anonymous Procurement & Intake: Wherever feasible, beds are purchased anonymously through standard consumer checkouts and inspected for unboxing expansion time and initial VOC off-gassing.
- 14-Night Break-In Period: All comfort layers undergo controlled break-in cycles before instrumented baseline scans begin so scores reflect true broken-in feel.
- Multi-Body Sleeper Panels: Testers across lightweight, medium, and heavyweight builds sleep on each model and log alignment, turning resistance, and morning soreness.
- Editorial Fact-Checking: Pricing tiers, sleep-trial exclusions, return haul-away fees, and law-tag materials (including fiberglass vs. silica/wool fire barriers) are verified directly against current brand terms.
- Peer Review & Medical Advisory Audit: Articles covering spinal alignment or chronic joint pain undergo clinical accuracy checks prior to publication.
4. Retesting & Corrections Policy
Mattress makers frequently swap foam densities, coil zones, or cover textiles without changing model names. When our editorial monitoring detects a spec change—or when a reader flags a factual discrepancy via our Contact Form—we verify the update within 48 hours, revise the review with an updated timestamp, and schedule physical retesting if core layers changed.
