Key Layer Breakdown & Product Highlights

Flippable Dual-Firmness Versatility (Firm & Extra-Firm)

Choose between a traditional Firm feel (7.5/10) on one side or flip it over for an Extra-Firm feel (9.5/10). This dual-sided design lets you customize your comfort while extending the overall lifespan of your mattress.

ACA-Endorsed Lumbar & Spinal Support

Tested and endorsed by the American Chiropractic Association (ACA) to reduce spinal stress and improve lumbar support. High-density comfort foams soothe pressure points across the hips and shoulders while keeping your spine in natural alignment.

6” Ascension® Firm Encased Coils

Optional GlacioTex™ Cooling Technology & Open-Cell Foams
