| Comfort | Featuring our RightTemp Wave Foam, our Harmony Lux Carbon Series sleeps cool and comfortable all night. 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. | Latex is naturally hypo-allergenic. Its anti-microbial properties inhibit dust mites, mold, and mildew from thriving. Because latex is a product of pin core construction with thousands of tiny air channels that provide natural ventilation. Mildew, staphylococcus and other bacteria can't live in latex foam, making it the perfect choice for allergy sufferers and anyone wanting to breathe, fresh clean air while they sleep. It keeps you warm in the winter and cooler in the Labor Day. The natural properties of latex layers allow air to flow naturally in the mattress. Latex whisks away moisture and regulates your temperature throughout the night, without trapping heat like traditional mattresses. Joma Wool is a high-quality natural fiber, grown in New Zealand and used worldwide by some of the most esteemed mattress and bedding manufacturers. Using wool provides better airflow, efficiently wicks away moisture, and serves as a natural fire barrier for the mattress. Wool is a natural solution, unlike other fire retardant chemicals used in many mattresses. |
| Support | 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. 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. | Latex relieves pressure that causes you to toss and turn at night. The ability of latex to gently support and conform to your body alleviates pressure points and dramatically reduces tossing and turning. The latex mattress itself reduces pressure areas by as much as 90%, thus ensuring a sound and comfortable sleep. Hidden inside latex is the secret to its adaptability and comfort. The natural and unique cell structure of the material allows latex to be flexible and envelop your body, while still supporting your body. The structure also provides relief for primary pressure points throughout the night. Dunlop latex provides essential support and often is firmer than Talalay latex. As a newer technology, Talalay latex provides a softer yet more consistent feel. For decades, customers have recognized that combining Dunlop base layers and a Talalay top layer provides the support most people need. |

FAQs
Beautyrest Harmony Lux Carbon
How many coils does Harmony Lux have?
The Beautyrest Harmony Lux models all feature the same pocketed coil support unit, which includes 850 coils (in the queen size) and provides zoned support.
What is the Seaqual Fabric Technology?
Seaqual is a collaborative initiative aimed at cleaning our oceans and raising awareness about marine litter. They convert ocean plastics into luxurious, high-quality sustainable fabrics. These fabrics not only feel great but also contribute to cleaner oceans. Each queen-size mattress made using Seaqual fabric helps to eliminate the equivalent of up to 50 water bottles from the ocean.
How do I know which firmness to select when I am mattress shopping?
The choice of mattress firmness is subjective and depends on your personal preferences and problem areas. Stomach sleepers generally benefit from a firmer mattress, while back sleepers find comfort in a firm to medium feel. Side sleepers often prefer a medium or plush mattress with extra pressure relief. These guidelines can assist in narrowing down options, but personalized recommendations based on individual needs can be obtained from the Customer Support team.
Sleep EZ Natural Latex
With this mattress, what kind of base may I use?
You can use any strong and solid base, including adjustable bases. However, you should avoid slatted foundations with gaps of more than 3" and box springs with actual springs. The mattress is made of latex foam, a naturally breathable, open-celled material, so it doesn't require a slatted foundation for cooling. However, a slatted base can improve breathability and reduce the chances of mold on the mattress cover in high-humidity environments.
How does organic Dunlop differ from natural Dunlop?
Organic Dunlop latex and 100% natural Dunlop latex are not significantly different. The organic certification for latex indicates that the production process uses less water and power, has a smaller carbon footprint, and has a lower environmental impact. This certification ensures that the latex is better for the environment and the workers, but the final product is the same whether the latex is 100% natural or organic. This is why there is no organic Talalay available, as the Talalay process is more complex, uses more water and electricity, and cannot meet the organic latex certification's reduced water and electricity usage requirements.
Is the latex blended or does it contain any man-made rubber?
All of the latex sold by us is made from 100% natural rubber harvested from a rubber tree. The final product is 98% pure rubber, with the remaining 2% consisting of natural fatty acids, natural soaps, and natural reinforcing agents needed for manufacturing.
