Description

The Serta iSeries NXG

Exceptional Support for Proper Alignment

Built with a 5‑zoned coil system, this mattress delivers targeted support to the areas of your body that need it most. Alternating firm and plush zones help maintain proper spinal alignment, while BestEdge® Support reinforces the perimeter for consistent, edge‑to‑edge stability. The result is a sleep surface that feels balanced, supportive, and dependable night after night.

Deep, Contouring Pressure Relief

High‑density NXG™ Memory Foam provides advanced pressure‑relieving performance. This premium material adapts closely to your body’s natural curves, easing tension in the shoulders, hips, and lower back. Its durable, high‑density structure ensures long‑lasting comfort and a more restorative sleep experience.

Cool-to-the-Touch Comfort All Night

A CoolFeel™ Cover creates an immediate cooling sensation the moment you lie down, helping you relax and fall asleep faster. Beneath the surface, Carbon Fiber Memory Foam works to draw heat away from the body, promoting consistent temperature regulation throughout the night. These cooling technologies work together to keep you comfortable, even in warmer environments.

Reduced Motion for Undisturbed Sleep

Thoughtfully engineered to minimize the transfer of movement, this mattress helps ensure that partner activity doesn’t interrupt your rest. The combination of responsive foams and individually supportive coils absorbs motion, allowing both sleepers to enjoy a more peaceful night.

Thoughtful Materials and Hybrid Construction

Designed with a tailored feel and a focus on performance, this mattress blends advanced foams with a supportive coil system to deliver the sleep experience you’ve been looking for. Immediate cooling, targeted support, and deep pressure relief work together to create a balanced, comfortable surface at a price that makes sense. The hybrid design enhances responsiveness and durability, making it a smart choice for sleepers who want both comfort and long‑term performance.

Safe and Sustainable Materials

The Serta iSeries NXG mattress is CertiPUR-US® Certified, ensuring it’s free from harmful chemicals and gases. This makes it a safer choice for your family and the environment. For more details, visit CertiPUR-US®.

Simple Cleaning Tips

If spills occur, sprinkle baking soda on the area, let it sit for 15 minutes, and vacuum thoroughly. Regular airing will also preserve its comfort and freshness. For more care tips, explore our Mattress Care Guide.

Compatibility with the baselogic™ Platinum Adjustable Base

Pair the Serta iSeries NXG with the baselogic™ Platinum Adjustable Base to transform your sleep. This adjustable base lets you customize your sleeping position to enhance spinal alignment and circulation. Built for durability, it complements the mattress perfectly, creating a seamless and luxurious sleep system.
