The Glacier Reserve™ Medium Euro Top Split Head Mattress is designed for sleepers who want a perfect balance of responsive support, refined comfort, and advanced cooling. Hand-applied tufts add a tailored, luxurious touch while helping maintain even comfort across the Euro Top surface. At the comfort layer, the FLOWT™ spiral gel grid gently flexes to support and lift your body, promoting free airflow and a cool, weightless feel. Beneath, Flexara™ memory foam provides adaptive contouring and reduced motion transfer, while dual layers of HyperGel™ cooling memory foam work together to absorb and dissipate heat for consistent temperature balance throughout the night. Individually encased coils complete the design with personalized support, enhanced airflow, and long-lasting durability—making Glacier Reserve™ ideal for those seeking medium comfort with elevated craftsmanship and all-night cooling performance.

The FLOWT™ mattress collection is designed for people who want more from their sleep—more comfort, more support, and more balance through the night. Built around a progressive spiral gel grid, FLOWT delivers a truly weightless sleep experience that adapts to you, not the other way around.
