Serta® iSeries NXG1300 Luxury Tight Top Medium King Mattress

Drift into deeper, cooler sleep with the Serta iSeries NXG1200. Built with next generation technology, this mattress is made for comfort that works the moment you lie down. From the first touch, the cool-to-the-touch cover helps keep your body at a steady, comfortable temperature all night. A blend of PE yarns, graphite and gel foams works together to manage heat while you sleep. Inside, the graphite and gel memory foams respond right away to your movements. They gently cradle your body while pushing back with the right level of support, so you never feel stuck or overheated. At the core, five support zones work together to keep your spine in healthy alignment. Each part of your body gets the support it needs, right where it needs it most. The result is a balanced, refreshing sleep that helps you wake up rested, restored and ready for the day.
