Plush comfort. Cooling performance. Gentle contouring.

 

The Serta iSeries NXG 2500 All-Foam Plush mattress is designed for sleepers who crave a softer, more enveloping feel without compromising proper support. Its plush comfort layers allow the body to gently sink in, relieving pressure at the shoulders and hips—key areas for side sleepers—while still providing the underlying stability needed to maintain healthy alignment.

 

Advanced cooling materials help regulate temperature and prevent heat buildup, ensuring consistent comfort throughout the night. The responsive foam construction adapts smoothly to movement, while motion-isolating layers reduce disturbances caused by a partner’s movements. The result is a plush yet supportive sleep surface that feels cozy, pressure-relieving, and comfortably balanced.

 

Best for side sleepers and comfort-focused sleepers who prefer a softer feel with pressure-relieving contouring and cooling comfort, as well as couples seeking reduced motion transfer.
