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, as 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; however, both mattresses also include lower-quality foams.
