Comfort & Feel
Back Support
The 50 firmness settings allow you to adjust the mattress’s firmness for maximum back comfort. The mattress’s combination of memory foam and latex layers helps to distribute weight evenly, minimizing pressure points that can exacerbate back pain.
Firmer quilting and gel-infused foam in the center third of the mattress provide enhanced back support. The Therapeutic Support Core™ offers maximum pressure relief that can help alleviate discomfort associated with serious and chronic back and joint conditions.
Cooling Features
Solaire’s cover is made from naturally breathable organic cotton, which helps wick away moisture and contribute to a cooler sleep surface. A 2″ layer of gel-infused memory foam helps draw heat away from the body. Below this layer is a 1″ natural latex layer known for its breathability and ability to regulate temperature. Solaire’s core consists of air chambers that can be individually adjusted for firmness, while allowing for airflow to prevent heat buildup and promote a cooler sleep environment.
The cover is made with breathable organic cotton that sleeps cool. The mattress also contains cooling gel-infused foam that helps disperse body heat and proprietary foam with cooling graphite. The individually-wrapped coils also allow for great airflow.
Firmness Options
50 distinct firmness settings to choose from, as measured by the scientific pressure standard of millimeters of mercury (mmHg)
The Saatva Rx comes in one firmness: Supportive Plush. It’s best suited for side sleepers but also great for back and combination sleepers and stomach sleepers under 130 pounds. The plush surface helps relieve pressure points.
