Our Verdict
Serta Perfect Sleeper Innerspring
Sealy Posturepedic Hybrid
The Sealy Posturepedic Hybrid and the Serta Perfect Sleeper Innerspring are both hybrid mattresses with a medium-plush feel. The Sealy is a better choice for most people since it offers better cooling and better motion isolation. The Serta has a more contouring feel, which you might prefer, and has a better edge support performance. The Serta uses one layer of good-quality polyfoam, which is more durable, but both mattresses include lower-quality foams as well.
