Discover the perfect sleep balance with the Serta® iSeries® NXG™ 2500 Hybrid Medium Mattress, where next-generation sleep innovation meets versatile comfort for every sleeper. This thoughtfully engineered hybrid mattress delivers immediate cooling comfort, instant pressure relief, and ideal support for a deeper, more restful sleep at a price that makes sense. Featuring advanced NXG Memory Foam technology and a precision-crafted 5-zone coil system, this medium mattress creates the optimal sleep environment for all sleep positions—side, back, and stomach sleepers alike. Experience how innovative cooling technology and contouring pressure relief work together with balanced support to transform your nightly rest into a rejuvenating experience.


Experience cooler sleep from the very first moment you lie down with immediate cooling technology that activates instantly. The CoolFeel™ Cover provides that refreshing cool-to-the-touch sensation that helps your body transition into sleep mode faster, eliminating the uncomfortable heat buildup that can delay sleep onset and disrupt your rest.
Working in perfect harmony with the cover, Carbon Fiber Memory Foam continuously draws heat away from your body throughout the night, effectively redistributing warmth and maintaining a balanced sleep temperature. This integrated dual-layer cooling system keeps you comfortably cool from bedtime through morning, transforming hot, restless nights into refreshing, uninterrupted sleep.

The 2500 Hybrid Medium incorporates innovative NXG™ Memory Foam—a premium, high-density memory foam that delivers exceptional contouring pressure relief while maintaining the balanced medium support your body needs. This advanced foam technology adapts to your body's natural contours, distributing weight evenly and eliminating pressure points that can cause discomfort, all while providing the ideal foundation for proper spinal alignment across all sleep positions.
Perfect for side, back, and stomach sleepers who need versatile support, the NXG Memory Foam contours to your unique shape without allowing excessive sinkage or feeling too firm. The medium feel ensures your spine stays properly aligned while pressure-sensitive areas like your shoulders, hips, and lower back receive the relief they need. This creates a sleep surface that supports your body's natural posture while eliminating the pressure points that can disrupt restorative sleep, regardless of how you prefer to sleep.

The advanced 5-Zone Coil Support System represents a revolutionary approach to personalized mattress support. This intelligent design features strategically positioned alternating firm and plush zones that work together to support the natural curves of your back and body. Unlike traditional uniform coil systems, this zoned technology recognizes that different body regions require different levels of support for optimal alignment.
Your shoulders and hips benefit from plush zones that allow natural contouring, while your lumbar region and core receive enhanced firm support that maintains proper spinal alignment. This precision-targeted approach ensures every part of your body receives the ideal level of support, promoting healthy sleep posture and reducing the morning stiffness or discomfort that can result from improper alignment, regardless of whether you sleep on your side, back, or stomach.

Enjoy the tranquility of undisturbed sleep with the 2500 Hybrid Medium's sophisticated motion control design. The strategic combination of memory foam layers and pocketed coil system works harmoniously to absorb and minimize the impact of your partner's movements, ensuring that nighttime activity doesn't disrupt your restful sleep.
This motion-isolating technology proves especially valuable for couples with varying sleep schedules or different movement patterns. Whether your partner rises early, shifts positions frequently, or gets in and out of bed during the night, you'll experience uninterrupted sleep thanks to the mattress's ability to contain and isolate motion within individual sleeping zones.

BestEdge® Support technology guarantees that every square inch of your mattress delivers consistent support and stability, from the center to the very perimeter. This advanced edge support system prevents the sagging and compression common in traditional mattresses, maximizing your usable sleep surface and providing a solid, stable edge for sitting or sleeping near the perimeter.
Whether you prefer sleeping near the edge, need additional space for stretching out, or simply value the confidence of knowing your mattress maintains its shape over time, BestEdge® Support provides lasting edge-to-edge stability. This technology ensures your mattress preserves its support characteristics throughout its entire lifespan, delivering consistent comfort and medium firmness wherever you choose to sleep.

The iSeries NXG 2500 Hybrid Medium is CertiPUR-US® Certified, ensuring all foam components undergo rigorous testing and verification to be free from harmful chemicals and gasses. This certification confirms that your mattress meets stringent standards for content, emissions, and durability, giving you complete confidence in the materials you sleep on every night.
This dedication to responsible manufacturing means you can sleep soundly knowing your mattress delivers not only exceptional comfort and support but also uncompromising safety for you and your family. The CertiPUR-US® certification reflects a commitment to quality, safety, and environmental responsibility that goes beyond comfort to encompass your complete health and well-being.
