The Serta iSeries NXG 2500 Plush Mattress brings together next-generation memory foam comfort and zoned pocketed coil support in a luxurious 12.5-inch hybrid build.

Cloudy Mattress is an Authorized Serta dealer, so every purchase is backed by the full manufacturer warranty. The feel sits firmly on the plush side of the comfort scale, delivering the cushioned cradling that side sleepers often seek. Because of this cushioned response, it ranks among the best plush hybrid mattresses for side sleepers options for pressure relief at hips and shoulders.

Inside, multiple engineered components work together, starting with a CoolFeel™ cover that delivers immediate cool-to-the-touch comfort the moment you lie down.

This Serta iSeries 2500 12.5 inch Plush Hybrid uses NXG Next Generation Memory Foam for deep, contouring pressure relief that cradles the body's curves. Furthermore, a Carbon Fiber Memory Foam layer actively draws heat away from the body, supporting all-night temperature regulation for hot sleepers.

This cool-to-the-touch breathable cover works together with the carbon-fiber foam to deliver consistent cooling from the moment you settle in. Beneath the comfort layers, the 5-Zone Coil System features alternating firm and plush coil zones that better support the natural curves of your back and body.

This zoned individual pocketed coil system delivers targeted spinal support while still providing the plush surface feel that defines this model. Furthermore, the pocketed construction provides advanced motion isolation for couples, making it a strong choice for those sharing the bed.

A BestEdge® Support system reinforces the perimeter, delivering edge-to-edge sleep surface stability that maximizes usable sleeping area. Together, these layers deliver a restorative sleep technology experience with deep pressure point relief and cloud-like soft comfort. At a 12.5-inch profile, this plush memory foam hybrid mattress Serta model is fully adjustable base compatible and pairs seamlessly with modern foundations.

Additionally, the mattress is built with CertiPUR-US certified foam and backed by a 100-night in-home sleep trial and a 10-year limited Serta warranty..

Key Mattress Benefits

6 Layers
Of Cooling
Comfort

The exterior cover features cool-to-the-touch fabric that delivers immediate cooling the moment you lie down. Its breathable design supports the cooling system across the entire surface of the mattress.

This top layer is high-density NXG Next Generation Memory Foam that delivers deep, contouring pressure relief. As a result, sleepers benefit from cradled comfort at the shoulders, hips, and lower back where pressure tends to build.

This support and cooling layer is infused with conductive carbon fibers engineered to actively draw heat away from the body. Furthermore, this redistributes warmth across the mattress for consistently cool, comfortable sleep through the night.

The support core features individually wrapped pocketed coils arranged in five zones with alternating firm and plush areas. This zoned design provides targeted support for different parts of the body, with firmer coils beneath the core and softer coils at the shoulders and legs.

A reinforced perimeter is built into the mattress for edge-to-edge sleep surface stability. This system maximizes the usable sleeping area and provides a stable sitting edge when getting in and out of bed.

This high-density base foam anchors the entire mattress build and supports long-term durability. It helps maintain consistent shape, performance, and stability for years of dependable use.

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Yes, the iSeries NXG 2500 Plush is an excellent choice for side sleepers. The plush NXG Memory Foam top layer cradles the shoulders and hips where side sleepers need the most cushioning, while the 5-zone pocketed coil core delivers targeted support to keep the spine in healthy alignment.

The NXG 2500 is a hybrid mattress. It combines layers of memory foam at the comfort surface with a 5-zone pocketed coil support core. This design delivers the contouring comfort of foam with the responsive bounce, breathability, and motion isolation of an innerspring coil system.

The NXG 2500 is specifically engineered to sleep cool. It features a cool-to-the-touch CoolFeel cover for immediate cooling, plus Carbon Fiber Memory Foam that actively draws heat away from the body throughout the night. Combined with the airflow benefits of the pocketed coil core, this delivers consistent cooling for hot sleepers.

Both mattresses share Serta's NXG Memory Foam comfort foundation. The 2500 generally represents a step up in the iSeries NXG lineup with additional comfort layering and refined feel options. For exact current spec differences between the 1500 and 2500 models, we recommend confirming directly before purchase since the lineup is updated periodically.

Yes, the Serta iSeries NXG 2500 is fully adjustable base compatible. You can pair it with your preferred adjustable foundation for personalized positioning, including elevating the head or foot of the bed for reading, watching TV, or zero-gravity rest.
