Harmony Lux Carbon Series Extra Firm

Starting at

Beautyrest’s new Harmony Lux collection brings the latest sleep innovations into perfect harmony with environmental responsibility.  The Harmony Lux Carbon Series Extra Firm mattress is the firmest model in the collection.  Find cooling technology, pressure relieving materials, coupled with a worthy cause, the Harmony Lux Carbon Series Extra Firm mattress targets a specific type of sleeper looking for a specific type of comfort solution.

Top Layers of Comfort
Starting at the sleep surface, all Harmony Lux products include high-quality, sustainable fabrics made in partnership with SEAQUAL, the leader in ocean plastic recycling efforts.  By recycling and transforming ocean waste into a continuously woven yarn, each mattress from the Harmony Lux line helps eliminate approximately 50 water bottles from our oceans.  The mattress surface also features InfiniCool Lux Technology that is cool to the touch and works to deplete heat buildup for the sleeper.  Directly beneath the cover find comfort layers such as 1″ RightTemp Wave Foam, 2.5″ total of Firm Comfort Foams and .5″ of Beautyrest Gel Memory Foam.  These layers help ensure that a firm sleep surface also provides excellent pressure relief to reduce tossing and turning at night.

Core Layers of Support
Harmony Lux utilizes a Precision Support System powered by T2 Pocketed Coil Technology. This support system promotes additional support in the center third of your mattress where the bulk of our body weight exists.  This added support enhances healthy back support while helping to distribute body weight evenly across the sleep surface.  The T2 Pocketed Coil features double to reduce motion and promote long lasting durability.

Our recommendation
We recommend this mattress for a specific type of sleeper that wants a harder sleep surface.  The ideal customer for the Harmony Lux Carbon Series Extra Firm mattress is a back or stomach sleeper.   We advise side sleepers to step over in the Plush or Plush Pillowtop version of this mattress.
