Our Verdict
Sealy Posturepedic Plus Mount Auburn
Beautyrest Mattress
The Beautyrest Mattress is better than the Sealy Posturepedic Plus Mount Auburn for most people. These mattresses have a similar medium-firm feel, with moderate sinking and low contouring. However, the Beautyrest offers better cooling and significantly better motion dissipation. It's also much more responsive, which prevents you from feeling stuck in place. The Sealy includes denser foam layers that make it a bit more durable, but they aren't quite dense enough to be considered good quality.
