Serta iSeries NXG 3500 Firm Hybrid Twin XL Mattress with Low Profile Box Spring

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.
