Serta iSeries NXG 3500 All-Foam Medium Mattress

Balanced comfort. Adaptive support. Advanced cooling.

The Serta® iSeries NXG™ 3500 All-Foam Medium mattress is
thoughtfully designed for sleepers who change positions throughout the night and for couples with different comfort needs. Its medium feel delivers the ideal balance of cushioning and support, allowing the mattress to gently contour to your body while preventing excessive sink. This adaptive comfort helps relieve pressure at the shoulders and hips when side sleeping, while still providing the stability needed for back and stomach sleeping positions.

Advanced memory foam layers respond quickly to movement,
making it easier to shift positions without feeling “stuck,” while the all-foam construction minimizes motion transfer to reduce sleep disruptions from a partner’s movements. Cooling technologies work together to regulate temperature and maintain consistent comfort across the sleep surface, helping both sleepers
rest comfortably throughout the night. The result is a versatile, balanced sleep experience that supports deeper, more uninterrupted rest for a wide range of sleep styles.

Best for combination sleepers who change positions during the night and couples seeking balanced comfort, pressure relief, and
motion isolation.
