We’ve evolved the Serta® iSeries NXG™ to be the next generation of comfort. We’ve built this Firm feel mattress with a series of benefits for the sleep you want. Experience immediate cooling, instant pressure relief, and ideal support for a deeper , more restful sleep at a price that makes sense. Featuring high-density memory foam, NXG™ Memory Foam delivers deep, contouring pressure relief. A cool-to-the-touch fabric offers instant cooling, while Carbon Fiber Memory Foam draws heat away from the body for all-night comfort. The hybrid models feature a 5-zone coil system with alternating firm and plush areas to better support the curves of your back and body.
