Stepped Up Comfort and Support

by David Higgins

A step up in the Harmony Lux Line, the Harmony Lux Hybrid Trilliant Series Firm offers advanced comfort layers for superb pressure relief. The Trilliant features enhanced comforts, targeted support, and environmentally conscious materials.

Top Comfort Materials

At a 3 on the comfort scale this mattress offers a very firm feel with just enough softness at the surface to help you drift off to sleep. The quilt includes ContourFit Design which allows you to find your perfect sleep position and stay there through the fight. The design allows you to feel the effects of the comfort padding layers below the surface. The first comfort layer is the Micro Diamond Memory Foam which includes actual diamond fragments throughout the memory foam which help pull heat away from the body. The EverGel HD Gel Memory Foam is a high density material that contours to your body to relieve pressure. The next layer is the Dynamic Response Memory Foam which is ventilated to increase breathability through the mattress while the foam provides additional pressure point relief to keep you free from aches and pains. Finally the Firm Comfort Foam offers that overall firm feeling support.

Targeted Support

The T2 Pocketed Coil Technology consists of durable double strand braided coils concentrated in the center of the mattress to provide extra support where we require the most support. The pocketed design means that the coils can move individually to better respond to your body and reduce motion transfer across the mattress.

Extra Cooling Capability

The InfiniCool Max system in the quilt provides two layers of cool to the touch material just below the surface for an initial cool feel to help you fall asleep quicker. A layer of Micro Diamond Memory foam helps to pull heat away from you as you sleep to keep your temperature comfortable all night.

Sustainable Sleep

Each mattress in the Harmony Lux line was made in partnership with Seaqual. Seaqual has created a soft and comfortable material made from plastic bottles removed from the oceans and used in the quilt of the mattress.

Support From Edge to Edge

The BeautyEdge Foam Encased Edge offers a durable border all the way around the mattress. This allows an increased sleep surface as you can sleep right up to the edge while still feeling the comfort and support that the mattress has to offer.

Is the Harmony Lux Trilliant Series Medium right for you?

With its high innovative comfort layers and targeted support system this is a great choice for anyone who prefers a firmer feeling mattress that is not too hard. A firmer feel like this is fit for back and stomach sleepers.
