Harmony Lux uses comfort technology that sets the bar high for other brands in the industry. They've introduced a channeled design with their RightTemp Wave Foam that allows for better airflow. The foam uses carbon fiber, which improves support and draws heat away from the surface, allowing more comfortable, cool sleep.

By partnering with Seaqual, an ocean cleanup leader, Beautyrest has produced a unique quilt made of repurposed plastics claimed from the ocean. By making use of these on every mattress in the Harmony Lux collection, they're helping lead to a cleaner world.

Beautyrest's development of the T2 Coil System is a significant advancement for their brand. This coil system that combines two coils into one is one of the most conforming coil systems available and has a strong, supportive feel. The system is used in the center 3rd of the mattress to provide more support for the heaviest part of the body.

The HLC-1000 has a full foam encased edge support that keeps the comfort consistent all the way to each edge. It prevents that roll-off feeling and makes the edge sturdier for sitting.

The non-prorated warranty's 10-year time frame means you can expect this mattress to provide comfort and support for a decade at the minimum.

If you like the extra firm feel, and want a great mattress in the mid-range of prices, the HLC-1000 Extra Firm is a superb option. Beautyrest has upped their quality with premium components, and their commitment to a better world, creating one of the best mattresses you'll find at this price point.
