Harmony Lux is all about new comfort technology that sets the bar for other brands. RightTemp Wave Foam introduces a channeled design to improve air flow and uses carbon fiber to improve support as well as conduct heat away from the surface, resulting in cooler sleep.

Beautyrest partnered with Seaqual, the leader in ocean cleanup, to produce a unique quilt, made from claimed and repurposed ocean plastics. Each queen size mattress uses the equivalent of 50 plastic bottles, leading to a cleaner, more comfortable world.

The new T2 Coil System makes a significant jump forward for Beautyrest. This coil system combines two coils into one, leading to a stronger, more supportive feel, that remains one of the most conforming coil systems on the market. This system is used in the center 3rd of the mattress, for more support where you need it most.

The HLC-1000 features a full foam encased edge support, for consistent comfort, even when sleeping to the edge. This feature is especially nice if you share a queen size, because couples can utilize the entire sleep surface and not feel like they're forced toward the center.

With a 10 year non-prorated warranty, this mattress is made to provide comfort and support well into the next decade.

If you enjoy an extra firm comfort level, and want one of the best mid range mattresses available today, then the HLC-1000 Extra Firm is an excellent choice. Beautyrest has really stepped up their quality, components, and commitment to a better world, and created one of the best mattresses available at this price point.
