Lab Verdict
Bear Elite Hybrid held heat-neutral better than the Serta iSeries Hybrid (2.7°F surface rise vs. 3.3°F). Motion isolation was roughly equivalent; either is safe for a partnered sleeper. The Bear Elite Hybrid relieved more shoulder pressure for side sleepers (27 mmHg vs. 32 mmHg). Perimeter compression was nearly identical — neither bed is the obvious pick on edge support alone. Combo sleepers will get more rebound from the Serta iSeries Hybrid (58% bounce vs. 36%).
