Therapedic TheraLuxe HD ICE Whitney Luxury Firm
Heavy-duty support with a cooler, more refined luxury-firm feel
The Therapedic TheraLuxe HD ICE Whitney Luxury Firm is the firmer model in the HD ICE lineup. It takes the heavy-duty coil and edge-support story from the HD collection and adds a cooler cover, natural latex, and a NanoCoil® micro-coil layer for a more refined, breathable, responsive feel.
The Whitney is for customers who want firm support, but do not want the mattress to feel basic, flat, or overly hard.
Comfort and feel
The Whitney has a luxury-firm feel. It is firm and supportive, but more cushioned and responsive than the Jackson. The latex and micro-coils give it a more buoyant, lively feel, while the XtraCool® cover helps the surface feel cooler to the touch.
It is a good fit for back sleepers, combination sleepers, hot sleepers, larger sleepers, and anyone who wants a firmer HD mattress with more comfort technology.
Best for
- Back sleepers
- Combination sleepers
- Larger or heavier sleepers
- Hot sleepers
- Customers who want firm support without a rock-hard surface
- Shoppers who want HD construction with latex, micro-coils, and cooling
- People who want durability but still want a premium feel
Heavy-duty support system
The Whitney uses the TheraLuxe QLX® HD pocketed coil core, with 1,872 17-gauge coils in queen size. This heavy-duty spring system gives the mattress deep support, better motion separation, and a more stable feel than many standard coil units.
Comfort materials
The Whitney adds a 2-inch layer of GOLS-certified natural Dunlop latex and a NanoCoil® micro-coil layer. Latex adds resilience, responsiveness, and durability, while the micro-coils improve airflow and give the mattress a more adaptive comfort feel.
This combination helps the Whitney feel firm, but not dead or board-like.
Edge support and cooling
The Whitney uses a 3-inch TheraEdge™ foam encasement made from 50-lb compression foam around the perimeter of the spring unit. The XtraCool® stretch-knit cover helps the mattress surface feel cooler and more temperature-conscious than a standard firm mattress.

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.
