Therapedic TheraLuxe HD ICE Everest Pillowtop
A plush pillowtop mattress built with heavy-duty support underneath
The Therapedic TheraLuxe HD ICE Everest Pillowtop is the plush, pressure-relieving model in the HD ICE lineup. It is designed for customers who want a softer, more luxurious pillowtop feel but do not want the common weakness of many soft mattresses: early body impressions, weak edges, and a lack of support underneath.
This is the HD mattress for people who want comfort first, but still need durability to matter.
Comfort and feel
The Everest has a plush pillowtop feel. It is softer than the Whitney and gives more pressure relief at the shoulders and hips. The top feels cushioned and more enveloping, but the HD support system underneath keeps the mattress from feeling unsupportive.
It is a strong choice for side sleepers, plush-bed shoppers, and larger sleepers who want softness without giving up structure.
Best for
- Side sleepers
- Plush-bed shoppers
- Larger or heavier sleepers who prefer a soft mattress
- Customers who want pressure relief but still need support
- People who like a luxury hotel-style pillowtop feel
- Shoppers who have had soft mattresses break down too quickly
Comfort materials
The Everest uses a plusher comfort package than the Whitney. The current product page lists an XtraCool® cooling stretch-knit cover, high-density quilt foam, HyPurGel® plush foam, plush natural latex, and a NanoCoil® micro-coil layer.
This combination gives the Everest its pressure-relieving top while still using materials designed to hold up better than typical low-density plush foam.
Heavy-duty support system
Under the pillowtop comfort package, the Everest uses the TheraLuxe QLX® HD wrapped coil unit. In queen size, the mattress uses 1,872 17-gauge Quantum encased coils for deep support, motion separation, and long-term stability.
Edge support and foundation
The Everest uses a reinforced TheraEdge™ foam encasement with 3 inches of 50-lb density compression foam around the spring unit. For best long-term support, it can be paired with the TheraLuxe HD reinforced wood foundation or a suitable adjustable base.

Our take
The Everest is one of the best examples of why firmness and durability are not the same thing. It is soft, but it is not flimsy. For the customer who wants a plush pillowtop feel and has been disappointed by soft beds wearing out too soon, the Everest is exactly the type of mattress we want on the floor.
A Mattress Collection Built. To. Last.
Every day we listen to customers tell us the same story: appliances that fail after a few years, furniture that sags too soon, and mattresses that simply can’t keep up. A bed shouldn’t be one of the “disposable” items in your home. At Mattress Mart, we believe your mattress should be a durable investment in your sleep, not a short-term purchase you’re forced to replace before its time.
That’s why we proudly feature the TheraLuxe HD line by Therapedic—a collection built from the ground up for long-lasting support, exceptional durability, and real-world performance at an outstanding value. These mattresses use higher-density foams and a stronger, heavy-duty spring system than most beds on the market, so they hold their shape night after night, even for the largest sleepers and the most demanding households. They’re backed by one of the industry’s strongest warranty programs, reflecting the confidence Therapedic has in the materials and construction.
To complete the system, you can pair your TheraLuxe HD mattress with an adjustable base or with the Therability™ Heavy Duty wooden foundation, which features 20 cross-slats, 2×4 bracing, and a 105-lb build weight in queen for unmatched stability and support. This is a sleep setup designed not just to feel good in the showroom, but to stand up to years of everyday use.
If you’re tired of mattresses that break down long before you’re ready to replace them, it’s time to step up to something better. Come feel the TheraLuxe HD difference for yourself—we dare you to compare.
