Construction
Zenhaven is a dual-sided mattress. Above the highly durable latex support core is a layer of 5-zone latex that determines the comfort level. On one side is the softer Luxury Plush, which is ideal for side sleepers (but also great for back and combination sleepers); on the other side is firmer Gentle Firm, which is perfect for stomach sleepers or those who need or prefer a firm mattress. Above this is a layer of certified organic New Zealand wool that acts as a natural flame barrier and helps wick away moisture. Finally, the mattress has a quilted cover made with organic cotton and proprietary Lumbar Zone® Quilting for additional support.
The Saatva Rx features an individually-wrapped comfort coil unit and firmer coils in the side rails for edge support. On top of this durable base, the mattress has multiple layers of various body-contouring foams for extra back cushioning, micro coils to relieve pressure points, and breathable materials to ensure cool sleep.
Materials
The mattress is made with a combination of eco-conscious and healthier-for-you materials. This includes GOLS, GREENGUARD® Gold, and eco-INSTITUT® certified latex, certified organic New Zealand wool, and organic cotton.
In the Saatva Rx, you’ll find an individually-wrapped comfort coil unit made with 15-gauge steel for durability. This is topped with a Therapeutic Support Core™ featuring our proprietary Rx Wave-Tech® Foam Layer and cooling graphite and phase-change material (PCM); an innovative 1″ micro-coil layer; 2 ¾” high-density foam layer encasing the micro coils; ½” gel-infused memory foam lumbar crown; and Lumbar Zone® Quilting on the mattress surface for added back support.

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
The quilted cover made with breathable and hypoallergenic organic cotton promotes cooler, healthier sleep. Vented airflow channels in the latex comfort layer provide superb breathability and cooling.
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
