Our verdict
Serta iSeries NXG 1500 Hybrid Firm is part of Serta's current hybrid lineup. Serta lists the queen at $1,899 (list $2,199). Our score reflects a published specifications and research evaluation of the current model — construction, materials, published firmness, price-per-size and how it stacks up against the rest of the Serta range — rather than a completed lab protocol on this exact unit.

Sleep Position Analysis
Side Sleepers
The Serta iSeries NXG 1500 Hybrid Firm's firmer feel (7.5/10) is not ideal for most side sleepers. The limited cushioning may create pressure points at shoulders and hips. Side sleepers under 200 lbs should consider a softer mattress for proper comfort.
Back Sleepers
Back sleepers will find the Serta iSeries NXG 1500 Hybrid Firm's 7.5/10 firmness ideal for maintaining proper spinal alignment. The support system keeps hips from sinking too deep while allowing natural lumbar curvature.
Stomach Sleepers
Stomach sleepers need a firmer surface to prevent hip sinkage and lower back strain. At 7.5/10, the Serta iSeries NXG 1500 Hybrid Firm provides the flat, supportive surface stomach sleepers need.
Combination Sleepers
The Serta iSeries NXG 1500 Hybrid Firm's hybrid construction provides responsive support that adapts as you change positions. The coil unit gives back bounce that makes repositioning effortless.

The entry point into Serta's NXG hybrid range. Serta iSeries NXG 1500 Hybrid Firm is built around four-zone wrapped coil unit for even weight distribution.
Serta sells this model at $1,899 for a queen (list $2,199). That places it in the mid range in the current lineup, which runs from the $499 Classic innerspring up to the $3,599 iComfortPro Level Three. If your budget is fixed, the table above is the fastest way to see what a hundred dollars either direction actually buys you inside the same brand.
Construction and what the feel is like
The comfort stack is: CoolFeel cover — cover engineered for instant cool-to-touch contact; Carbon fiber memory foam — draws heat away from the sleep surface; NXG memory foam — high-density contouring foam; Q4 Zoned Support System — four-zone wrapped coil unit for even weight distribution.
In practice, that build gives a firm surface. Back sleepers sleepers get the most out of it; lightweight side sleepers will want to look one model up or down the range. Serta's zoned support systems all share the same idea — firmer coils or foam under the hips and lumbar, softer at the shoulders — so moving between models in this lineup changes the comfort layers far more than the support feel.
Trial, warranty and how we scored it
Serta.com sells this model with a 120-night trial and a 10-year limited warranty, with free shipping. Buying through a retail partner such as Mattress Firm or Costco changes both the trial terms and the price, so confirm the return window at checkout rather than assuming Serta's direct policy applies.
Our 8.4 score is an editorial score. It is not the output of a completed lab protocol on this individual unit, and we say so on every Serta page rather than implying testing we have not done.

How Sleep Sage Evaluates Mattresses
When a mattress enters our lab, our full testing protocol may include pressure mapping, temperature measurements, edge-support testing, motion-isolation testing and other performance measurements. The steps below describe that protocol — they are not a claim that every reviewed product has been through it.
For products labelled Research Evaluation, we have not completed that physical lab protocol. Those reviews are based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.
Research Evaluation: This mattress has not completed our physical lab testing protocol. Our evaluation is based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.
Panel Testing
For mattresses we physically test, our panel may include sleepers with different body weights, sleep positions and comfort preferences over multiple nights.
Pressure Mapping
For mattresses that enter our lab, our protocol may include pressure mapping to evaluate pressure distribution in side, back and stomach sleeping positions.
Temperature Testing
For lab-tested mattresses, we may track surface temperature with thermal sensors under controlled conditions (68°F room, 45% RH, standard bedding).
Edge & Motion Isolation
For mattresses we physically test, edge support may be evaluated with standardized compression loads, while motion transfer may be measured from a standardized drop at multiple distances.
Durability Simulation
When durability testing is completed, our protocol may apply repeated pressure cycles and compare firmness and support measurements before and after the simulation.
Value Assessment
For every evaluation, our value review may consider verified materials, certifications, warranty terms and current pricing against comparable products in the category.
Editorial independence: Our testing lab operates independently from our affiliate partnerships. Brands cannot pay for higher scores or influence our methodology. Read our full editorial policy and detailed testing methodology.
