How We Test
Every mattress we review is purchased at full price and tested in our sleep lab for 30+ nights. We measure pressure distribution, motion transfer, and temperature regulation — and we sleep on them.
Scoring Criteria
Every product receives a score from 0 to 10 based on weighted criteria. Here is exactly how we calculate it.
Comfort & Support
We test with sleepers across body types (120-280 lbs) and sleep positions (side, back, stomach, combo). Pressure mapping reveals support zones and potential pain points.
Durability & Materials
We evaluate foam density, spring gauge, cover quality, and certifications (CertiPUR-US, OEKO-TEX). Durability is projected based on material analysis and 1,000-cycle roller testing.
Value
We compare price-per-night over expected lifespan, trial periods, warranty terms, and return policies. We track price drops and flag misleading MSRP claims.
Temperature & Motion
We measure surface temperature over 8 hours using thermal sensors. Motion transfer is tested with a partner simulation rig (dropping a 15-lb weight and measuring disturbance).
Tools & Equipment
The tools we use to produce consistent, reproducible results.
- XSENSOR pressure mapping system
- Thermal sensors for temperature tracking (8-hour cycles)
- Motion transfer measurement rig
- 1,000-cycle roller durability tester
- Multiple sleeper panel (side, back, stomach, combo — various body types)
Independence Pledge
- No sponsored rankings. Our scores are never influenced by advertising or affiliate relationships.
- We buy everything ourselves. Products are purchased at retail price with our own funds. No vendor-supplied review units.
- Affiliate transparency. We earn commissions from some links. This funds our testing but never affects our scores. Full disclosure.
- Corrections policy. If we get something wrong, we update the article with a visible correction notice and date.
Update Cadence
Mattress reviews are updated with model refreshes. Sleep tech is re-tested every 6 months. Price tracking runs daily.
Every article shows its publish date and last update date. If a review is more than 6 months old without an update, we flag it as potentially outdated.
