Beautyrest's Harmony Lux Diamond Medium Pillow Top is an excellent mattress for those who like a firm, solid feel but with a bit of initial contouring. In its class, it has the highest amount of premium materials, so its arguably the best firm pillow top mattress on the market.
The Harmony Lux beds introduce RightTemp Wave Foam which is effective at cooling due to its channeled design that increases airflow and because it uses carbon fiber to conduct heat away from the surface.MicroDiamond Memory Foam
Micro Diamond Memory Foam, which has only been seen in the ultra premium Beautyrest Black mattresses, is now featured in the Diamond. Outstanding at pressure relief, this premium comfort material uses diamond particles to disperse heat, and works well alongside the carbon fiber found in the Right Temp Wave Foam.New and Improved T2 Coil Technology
The T2 Coil System in the Diamond is one of the best available and adds support specifically in the lower back area, where it's most needed, by using T2 coils which are made with two strands of steel twisted together. It's a pocketed system, so it's conforming, and it's made from high carbon steel, making it highly supportive and durable. This coil system is adjustable base compatible and shows a step up in mattress support technology.Quilt With Seaqual sustainable fabric
Every Harmony Lux mattress has a quilt made in partnership with Seaqual, an ocean cleanup leader. Seaqual recovers plastics out of the world's oceans and transforms them into high-quality, eco-friendly fabrics that have a great feel. Each quilt uses a good amount of plastic, leading to a healthier, cleaner tomorrow.10 Year Warranty Tells of Durability
