Inside the Relax XC

The Harmony Relax XC features a specialized 10-inch, two-layer foam construction. This design maximizes both immediate comfort and long-lasting structural integrity under higher weight capacities.

  • The Comfort Layer: 2" CoolGel Flex High Capacity surface foam. This top layer delivers balanced, responsive comfort. Its thoughtfully firm surface aids in mobility, making rolling over and transitioning in and out of bed significantly easier, while actively dissipating heat for a cooler sleep environment.
  • The Support Core: 8" High Capacity base foam. This dense, ultra-durable foundation acts as the workhorse of the mattress, preventing bottoming out and ensuring years of reliable, heavy-duty support.

We thoroughly enjoy our beds and would highly recommend them!

Unlike a lot of reviews that people give right after they purchase, we have had our Harmony3 Adjustable Beds for three years.  We purchased two Twin XL mattresses and power bases, so we could adjust them separately. My wife and I love being able to sit up to watch TV or read books with full back support, and the mattresses are still like new and very comfortable. I can also lift the head of the bed as much as I want to control acid reflux or occasional snoring (me).  The remote control is easy to use, and has buttons for Zero Gravity, as well as head and foot adjustments and a "flat" button to return the beds to level. It even has a flashlight, and a massage button that vibrates and turns itself off.  We thoroughly enjoy our beds and would highly recommend them!
