Serta iSeries NXG

The Serta iSeries® NXG Hybrid collection is designed for sleepers who want the pressure relief of premium memory foam paired with the deep, supportive feel of an advanced coil system. By combining responsive comfort layers with individually wrapped coils, the NXG delivers a balanced sleep experience that adapts to your body while maintaining strong overall support and reduced motion transfer.

At the surface, a cool-to-the-touch sleep cover helps create a refreshing sleep environment from the moment you lie down. Beneath the cover, multiple layers of premium gel memory foam and latex-enhanced comfort materials work together to cushion pressure points, promote airflow, and provide a more responsive feel than traditional memory foam alone.

The hybrid construction allows the mattress to contour where your body needs relief while still maintaining the stability and support many sleepers prefer. Whether you sleep on your back, side, stomach—or change positions throughout the night—the NXG Hybrid is designed to help maintain proper spinal alignment while minimizing partner disturbance.

At the core, Serta’s individually wrapped coil support system responds independently to movement, helping reduce motion transfer while delivering targeted support across the mattress. Reinforced edge support creates a more stable seating and sleeping surface while maximizing usable sleep space.

The result is a mattress that blends advanced cooling, adaptive pressure relief, and dependable support into a sleep experience that feels both substantial and comfortable night after night.
