Spinal Alignment Support
Zoned support adapts to side, back & stomach sleepers.

4 Engineered Layers.
One Perfect Night's Sleep.
Every layer is designed with a specific job — from the first moment of contact to the deep spinal support beneath.
Copper-Infused Phase-Change Cover
Our proprietary thermic cover weaves copper fibers directly into the sleep surface. Copper conducts heat away from your body up to 25× faster than standard foam — keeping your sleep temperature stable all night.
Gel-Infused Comfort Memory Foam (2")
Cool Sleep™ gel micro-beads absorb and disperse residual heat while contouring to your body's pressure points — shoulders, hips, and lower back.
Individually-Wrapped Coil System (7")
960 individually-wrapped pocketed coils respond independently to your body's movements. Near-zero motion transfer means your partner's tossing and turning stays on their side.
High-Density Support Base (2")
A reinforced foam base locks in proper spinal alignment and provides long-term durability — ensuring this mattress performs like new for years to come.
