Serta iSeries NXG 1500 Hybrid Firm Mattress

Firm comfort. Cooling relief. Targeted support.

The Serta iSeries NXG 1500 Hybrid Firm mattress is designed for sleepers who prefer a firmer, more supportive feel with the added responsiveness of a hybrid design. Built with a series of benefits for the sleep you want, it delivers immediate cooling, instant pressure relief, and targeted support that promotes healthy spinal alignment. Its firm feel helps prevent excessive sink, while the hybrid construction combines contouring foams with zoned coil support for a stable, supportive sleep surface.

 

Responsive coils enhance ease of movement and reinforce support through the center of the mattress, while motion-isolating foams help reduce sleep disruptions. The result is a firm, cool, and supportive mattress that delivers durability, structure, and comfort night after night.

 

Best for back and stomach sleepers who need firm, reinforced support and sleepers who prefer a stable, responsive feel.
