Comfort Info Featuring our RightTemp™ Wave Foam, our Harmony Lux™ Carbon Series sleeps cool and comfortable all night. Sleep Cooler With Copper
Ever notice that copper pipes are always ice cold? We've discovered that copper is the preferred material for most cooling systems because it doesn't hold onto the heat around it. This combined with our open cell memory foam results in your mattress never getting hot.
Feel your best every morning, thanks to a superior design of our cooling gel memory foam combined with our patented heat transference technology. All through the night it wicks sticky dampness away and eliminates bothersome heat while keeping you in a refreshing state of pure sleeping bliss.
As our cooling gel memory foam dissipates your body heat, it maximizes your comfort. Experience the world's most elegant sleep surface, which is 30% cooler than a conventional mattress.
Foam Encased Comfort Edge: Increases usable sleep surface by allowing you to sleep all the way to the edge without feeling like falling off. Creates a better edge for entering, exiting and sitting on the side of the mattress.
Support Info Beautyrest® Harmony Lux™ Carbon Series features our latest innovations in support, comfort, and cooling that work together in harmony for a better night's sleep. Its new and innovative coil design and support system, advanced pressure relieving foams, uniquely engineered cooling technologies and exclusive sustainable fabric technology makes this collection the ultimate choice in premium bedding.
BeautyEdge® for reliable edge support.
Joint Pain Relief
The use of copper reduces joint inflammation and helps ease joint pain and stiffness. This is especially helpful for people with rheumatoid arthritis and osteoarthritis. We want our customers to be able to move around with as much freedom as possible.
Better Blood Circulation
People wear copper bracelets to improve their body's blood circulation. Since copper emits a number of antioxidants and anti-inflammatory properties, we thought that there would be no better way to improve your sleep than through improving your blood flow.
Our Plush Gel Memory Foam provides greater pressure absorption with superior recovery response for the ultimate memory foam sleeping experience. Combination Foam and Coils: Superior Pressure Relief. Contours to your natural shape to help achieve a comfortable sleeping posture. Hyper conductive foam regulates core temperatures for a natural sleep. Coils provide breathability and additional comfort and support.
Comfort Specs Consistently cool and comfortable
InfiniCool™ Lux is a system of layers in the cover and right below the cover that are cool-to-the-touch.
Copper-Infused Memory Foam
High density copper infused memory foam provides maximum comfort and cooling.
Highly breathable Memory Foam - rapidly channels heat away from the body. Patented gel technology dissipates body heat much faster than competitor's foam. Diamond Sparkle Foam actively regulates your core temperature for the most natural sleeping environment. Graphene and conductive flakes dissipate heat from the surface of the skin.
Wrapped coil design enhances airflow and breathability to keep you sleep environment more comfortable.
Support Specs Our Precision Support System™ powered by T2 Pocketed Coil™ Technology provides additional support where you need it most.
Beautyrest® Gel Memory Foam and RightTemp™ Wave Foam work together to create incredible pressure relief.
2.0 ILD Poly Base foam to provide overall support for the mattress in both comfort configurations. Cool Bliss GEL Memory Foam offers greater pressure relief promoting reduced tossing and turning for deeper, sound sleep. Greater compression brings greater support resulting in superior comfort without the traditional memory foam "bottom-out" under heavy loads. Great pressure relief and comfort through a wide range of temperatures resulting in uniform comfort in both cool and warm environments. Patented Zoned Support System: Adding 25% more support where you need it most
  1. Additional Wrapped coils in the center 3rd provided extra back support where you need it.
  2. Improves alignment by relieving pressure along the shoulders, back and hips
  3. Prevents motion transferred between partners for less disturbance
Diamond Sparkle Foam provides superior pressure relief for sound sleep.
Over 1,000 micro-coil act with independent suspension to create weightless pressure relief.
Fabric Specs Seaqual™ Fabric Technology utilizes recovered plastics from the ocean to create a durable and luxurious fabric. Our new covers now have a hexagon pattern. Not only did we make the new mattress cover double-sided, so you no longer have to remove the cover to flip it, but we've made it in a way that clearly distinguishes which side is soft, and which side is firm by labeling each side and making them two completely different colors. This makes it much easier for the customer to know which side they're sleeping on, and also saves time in the flipping process. In addition, we are the first mattress company in the world to implement a proprietary "softening" process to our fabric which you'll be able to feel makes our covers much softer than any of our competitor's. Luxurious 4-Way Stretch Cover, optimized for healthy pressure relief. Beautiful design and appearance that can be unzipped and removed for spot cleaning as needed. CoolTouch Advanced Regulating Fabric:
  • Advanced PCM coating regulates temperature so you can enter sleep more quickly and stay asleep longer
  • Actively moves excess heat away from the skin where it can dissipate to maintain a comfortable sleeping environment
  • Luxury stretch knit design contours to your body relieving pressure and enhancing conformability and pressure relief.
