Our Verdict

Sealy Posturepedic Plus Mount Auburn

Sealy Posturepedic Hybrid

The Sealy Posturepedic Hybrid performs better than the Sealy Posturepedic Plus Mount Auburn in most respects. The Hybrid is a higher-end model with better cooling, making it better-suited for hot sleepers, and better motion dissipation, so you're less likely to wake up when your partner moves. It features a contouring memory foam layer, yet maintains high responsiveness, making it easy to move around in your sleep. That said, the Mount Auburn offers much better edge support, which is important if you want to maximize the comfortable sleeping surface or make it easier to get in and out of bed.
