What sets it apart
The 1500 Hybrid Firm uses NXG memory foam, carbon-fiber memory foam and a five-zone coil support system.
Our take
This is the firmer baseline for the iSeries NXG hybrid range. Compare 2500 if you want the medium or plush choices absent from this model.
Reasons to consider it
Comfort layers over a spring core offer a way to combine cushioning with a more responsive underlying support system.
The tradeoff
Hybrid construction alone does not establish edge strength, motion isolation or cooling. Those vary with the specific layer design.
These comfort observations are editorial inferences from construction and published firmness, not results of hands-on testing.
Price and configurations
The recorded queen price is $1,899. This is a dated mattress-only offer, not a live checkout quote.
For context, the Perfect Sleeper X Quilted Top Hybrid Level Two starts at $1,799 in this catalog, $100 less than iSeries NXG Hybrid. Compare the construction and firmness below before treating the difference as an upgrade.
Price snapshot: September 10, 2026. USD, before tax. Delivery, accessories, bases and later promotions can change your total.
Trial, returns and setup
The product information advertises 100 nights for the home trial on direct purchases. Check the required adjustment period, pickup or return fees, condition rules, eligible foundations and warranty exclusions. A retailer purchase may have different terms.
