What sets it apart
ComfortMode Lux is an eleven-inch air-and-foam model, with an expanded comfort stack over the ten-inch ComfortMode.
Our take
The added comfort depth is the useful comparison with ComfortMode. Adjustable firmness and a thicker top layer are different things, so evaluate both.
Reasons to consider it
Adjustable firmness is useful when preferences change or partners want different settings.
The tradeoff
Air chambers and controls add components to service. Check what is covered throughout ownership and what costs extra.
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 $1,889.10. This is a dated mattress-only offer, not a live checkout quote. Bases and mattress-and-base systems are separate from this price.
For context, the ComfortMode starts at $1,439.10 in this catalog, $450 less than ComfortMode Lux. 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
Confirm the current home trial directly with the seller. Check the required adjustment period, pickup or return fees, condition rules, eligible foundations and warranty exclusions. A retailer purchase may have different terms.
