What sets it apart
This flippable all-foam mattress provides a Firm side and an Extra Firm side in one build. An optional sewn-in GlacioTex cooling cover changes the surface treatment but not the stated firmness.
Our take
The two-sided design looks practical for shoppers already committed to a very firm sleep surface but unsure how far to go. The cooling upgrade is a separate comfort decision rather than another firmness choice.
Reasons to consider it
A coil-free design is worth comparing if you prefer a quieter, less spring-driven response.
The tradeoff
A foam comfort stack may feel more enclosing and make position changes less effortless than a responsive spring or latex build.
These comfort observations are editorial inferences from construction and published firmness, not results of hands-on testing.
Price and configurations
The recorded queen configurations span $999 to $1,149. The lowest amount applies to the least expensive configuration observed, not every firmness, height or cover.
Distinct observed queen prices. Multiple options can share one price; these amounts do not identify a firmness on their own.
For context, the Firm Luxe starts at $1,198.50 in this catalog, $199.50 more than Firm. Compare the construction and firmness below before treating the difference as an upgrade.
Price snapshot: September 16, 2026. USD, before tax. Delivery, accessories, bases and later promotions can change your total.
Trial, returns and setup
Queen prices are without and with the GlacioTex cooling cover under code LABORDAY25. The trial requires at least 30 nights before a return, is limited to one use, and lists a $99 mattress return fee.
