Our Methodology

We sleep-test each mattress for at least 3 weeks with side, back, and stomach sleepers. We measure motion isolation with a seismometer, pressure mapping with a sensor pad, and edge support with calibrated weights. We also track temperature regulation overnight. No manufacturer has editorial influence.
