Lab Verdict
Bear Elite Hybrid ran measurably cooler in our 60-minute body-heat test (2.7°F surface rise vs. 3.3°F on the Serta iSeries Hybrid). Motion isolation was roughly equivalent; either is safe for a partnered sleeper. Side sleepers will feel less shoulder pressure on the Bear Elite Hybrid (peak 27 mmHg vs. 32 mmHg). Perimeter compression was nearly identical — neither bed is the obvious pick on edge support alone. Serta iSeries Hybrid returned more energy on rebound (58% vs. 36%), favoring combo sleepers.
