Our take on the iSeries NXG 2500 Plush King Mattress

The Serta iSeries NXG 2500 Plush is an all-foam king mattress built for sleepers who want a soft, contouring feel with cooling on top. A CoolFeel cover and carbon fiber memory foam pull heat away, while high-density NXG memory foam adds deep pressure relief. A dense foam core with Ultimate Edge Support keeps the perimeter firm for sitting and edge-of-bed sleeping. It competes with other all-foam beds on cooling and edge support rather than on hybrid coils, and it suits side and back sleepers who like a plush surface.

Owners of the iSeries NXG line generally like the cool-to-the-touch surface and the soft, contouring feel. Some heavier or hot sleepers say the foam still warms up and sinks more than they expected.

What people mention
  • CoolingMixedThe CoolFeel cover feels cool at first, but some owners say the foam still warms up overnight.
  • Pressure reliefPraisedSleepers report the memory foam cushions shoulders and hips well.
  • FirmnessMixedThe plush surface suits side sleepers but feels too soft for some stomach sleepers.
  • Edge supportPraisedOwners say the perimeter stays firm enough for sitting and sleeping near the edge.
  • Motion isolationPraisedCouples note little transfer of movement across the foam.

About the iSeries NXG 2500 Plush King Mattress

It has a cool-to-the-touch CoolFeel cover that cools directly from the surface.

Under the cover is high-density NXG memory foam, along with carbon fiber memory foam. The memory foam contours to the body for deep pressure relief. The carbon fiber memory foam contours as it cools and channels heat away from the body.

A high-density foam core provides support. Ultimate Edge Support surrounds the core for stability from edge to edge.

Questions and answers

Is the NXG 2500 Plush good for side sleepers?
Yes. The plush memory foam layers cushion shoulders and hips, which is where side sleepers feel pressure most. Stomach sleepers usually want something firmer.
Does it sleep cool?
The CoolFeel cover feels cool to the touch and the carbon fiber foam is designed to channel heat away. Some hot sleepers still find foam warms up through the night.
How does it differ from a hybrid iSeries?
This is an all-foam bed with no coils. Hybrid versions add innersprings for more bounce and a firmer feel; this one is softer and isolates motion better.
Will the edges hold up when I sit on them?
Ultimate Edge Support wraps the foam core to firm up the perimeter. It is stable for sitting and edge sleeping, though not as rigid as a coil-edge mattress.
Does it need a box spring?
A solid foundation or adjustable base works; a box spring is optional. Follow Serta's foundation guidance to keep the warranty valid.
What is in the box?
The mattress itself. A foundation or frame is sold separately, so plan for one before delivery.
