Stretch-knit fabric is enhanced with XtraCool™ Technology, which helps regulate temperature and wick away moisture for a cooler, more comfortable sleep. TheraTuft™ tufting adds durability by securing layers together, preventing shifting over time.
2 inches of 2.1 lb High-Performance foam is more durable,
supportive, and resilient than standard-density quilt foams (1.1–1.5 lb), which breaks down faster and loses its shape over time.
*An additional inch in the quilt vs the firmer model below it, the Jackson Firm, allows more conformity for hips and shoulders.
2 inches of 3 lb HyPURGel™ Ultra-Premium Foam. This is among the most important layers of material in the Everest as it provides the softness and durability on top of the firmer, latex later below.
1 inch of GOLS Certified Natural Dunlop Latex provides body-impression resistance, ease-of-movement, and additional breathability.
19 Gauge NanoCoil® takes the place of a foam layer, providing more breathability and durability than can foam. The NanoCoils respnosd even faster, helping make the surface of the mattress even more responsive and lively.
1" High-Density Foam replaces the Insulator pad of the Jackson to separate the comfort layers and the foam and to allow for a slightly more conforming feel in the Whitney.
The TheraEdge™ Ultra Firm Foam Edge Encasement System reinforces the mattress perimeter with solidly glued 3 inch, 50 lb compression, high-density foam, preventing edge sagging and maximizing the usable sleep surface.
The TheraLuxe QLX® HD All-Quantum Pocketed Spring Unit features 17-gauge, stress-relieved, and tempered wire, designed for heavy-duty use. With 1872 springs in a queen size, this system provides enhanced durability
A 1.5-inch extra heavy-duty balanced base polyurethane foam is glued to the bottom of the TheraEdge™ foam encasement, adding extra stability and ensuring long-term durability.
The HD Stands for HEAVY DUTY.
The Therapedic TheraLuxe HD ICE Everest Pillowtop is built for larger sleepers who desire actual durability, support, and longevity ALL from a mattress on the softer side. The additional layers include NanoCoil® and Dunlop latex, providing increased durability, breathability, and responsive, lively feel even for a firmer mattress.
