Our Verdict

Nolah Evolution

Sealy Posturepedic Hybrid

The Sealy Posturepedic Hybrid and Nolah Evolution have different strengths. Both are best for average-weight or heavier side sleepers and offer impressive motion isolation. The Sealy offers significantly better cooling and is more responsive, which makes it easier to move around on. On the other hand, the Nolah has a more hugging feel that helps it offer better pressure relief. You might prefer it if you like an enveloping mattress.
