Therapedic Thera Luxe HD Jackson Firm

The Therapedic Thera Luxe HD Jackson Firm is the firmest, most straightforward model in the Thera Luxe HD lineup. It is built for customers who want heavy-duty support, a firmer surface, stronger edge support, and better durability than a standard mattress.

This is not the softest bed in the store, and it is not trying to be. The Jackson exists for people who are tired of mattresses breaking down, sagging, hammocking, or feeling weak under them.

Comfort and feel

The Jackson has a firm, flatter feel with just enough cushioning to keep it usable. It does not have a deep pillowtop or plush surface. Instead, it gives you a stable, supportive sleep surface with minimal sink.

That makes it a strong option for back sleepers, stomach sleepers, larger sleepers, and anyone who knows they prefer firm support.

Best for

• Back sleepers
• Stomach sleepers
• Larger or heavier sleepers
• Firm-bed shoppers
• Customers who sit or sleep near the edge of the bed
• People who have been disappointed by mattresses that softened too quickly
• Shoppers who want heavy-duty construction at the lowest HD price point

Heavy-duty construction

The Jackson is built with the Thera Luxe QLX® HD wrapped coil unit by Leggett & Platt. This is a high-count, heavy-duty pocketed spring system using 17-gauge Quantum encased coils. In queen size, the unit contains 1,872 coils.

Above the coils, the Jackson uses 3 inches total of high-density polyurethane comfort foam: approximately 1 inch of 2.1 lb foam in the quilt and 2 inches of 3.0lb Thera Foam™ underneath. These foams are denser than the foams commonly found in many standard mattresses, which helps the mattress resist early softening and body impressions.

Edge support

The Jackson uses Thera Edge™ foam encasement around the perimeter of the mattress. The current product page lists 3 inches of 50-lb density compression foam around the spring unit, plus extra heavy-duty base foam bonded to the encasement for added stability.

That edge system helps the mattress feel more stable when sitting on the side of the bed and gives more usable sleeping surface from side to side.
