Our Verdict
Beautyrest Black
Sealy Posturepedic Hybrid
The Sealy Posturepedic Hybrid and the Beautyrest Black have different strengths. The Sealy performs better in terms of cooling, motion isolation, and edge support. The Beautyrest Black is a more responsive mattress, making it easier to move around in your sleep. It uses mostly good-quality foam, which is more durable. The Beautyrest has a medium firmness, making it better suited for average and heavier side sleepers. In contrast, lighter side sleepers might prefer the plusher feel of the Sealy.
