Our Verdict

Saatva Rx

Purple RestorePlus Hybrid

The Purple RestorePlus Hybrid offers a better performance than the Saatva Rx. The Purple is significantly more cooling, making it more suitable for hot sleepers. It offers better edge support and motion dissipation and uses denser, better-quality foam.
