Therapedic TheraLuxe HD ICE Whitney Luxury Firm

The HD Stands for HEAVY DUTY.

Therapedic TheraLuxe HD ICE Whitney Luxury Firm

Overview / Description
The TheraLuxe HD ICE Whitney Luxury Firm is where heavy-duty support meets a more refined, “cushion-firm” feel and cool-to-the-touch top. It builds on the same 17-gauge QLX® HD pocketed coil core as the Cascade, but adds a thick layer of natural Dunlop latex and a NanoCoil® micro-coil layer for extra responsiveness, breathability, and durability. The XtraCool® stretch-knit cover helps the surface feel cooler to the touch, and the overall feel lands in the firm-to-medium-firm range: solid, supportive, but not rock-hard.

Best For

  • Back and combo sleepers who want firm, “held-up” support with a bit more surface give than the Jackson.

  • Hot sleepers who like a firmer mattress but still want noticeable cooling and airflow at the surface.

  • Larger/heavier individuals looking for a coil-and-latex build designed for long-term durability, not just a soft top.

Key Features

  • Heavy-duty QLX® HD pocketed coil core (1,872 coils in queen) with 17-gauge Leggett & Platt springs – among their strongest pocketed units.

  • 2″ GOLS-certified natural Dunlop latex plus a NanoCoil® micro-coil layer for lively, responsive support and better airflow than foam alone.

  • 3″ perimeter of 50-lb compression foam for an exceptionally solid seating edge and usable sleep surface from side to side.

  • XtraCool® cooling stretch-knit cover over high-density quilt foams for a cooler, more temperature-neutral feel.

  • 20-year manufacturer warranty with a tighter 1″ body-impression standard when sold as part of the TheraLuxe HD program.

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.
