Therapedic Back Sense – Key Largo Pillowtop
Plush, pressure-relieving comfort with the support your back still needs
The Therapedic Back Sense Key Largo Pillowtop is made for shoppers who want a softer, more “cushioned” feel—without paying premium-mattress prices. It’s a strong fit for adult bedrooms, guest rooms, RV’s, and vacation homes where you want real comfort, dependable support, and a mattress that feels substantial.
With a plush, medium-soft surface and a stable innerspring support system underneath, the Key Largo Pillowtop is designed to conform more to your body and to settle in at the shoulders and hips while still keeping your spine in a healthy, more natural position.
Comfort layers built for pressure relief and better alignment
Instead of feeling “hard” or overly springy, the Key Largo Pillowtop uses a layered comfort package designed to soften pressure points while supporting the areas that matter most—especially through the lower back.
Quilted comfort layers:
* 1″ EverLast Foam
A durable quilt foam designed to add that initial “pillowtop” softness when you first lie down.
* 1″ High-Density Quilt Foam
Adds a more stable, supportive cushion so the top of the mattress feels plush—but not flimsy.
* Natural FR Fiber Barrier
A built-in fire barrier layer designed to meet safety standards without changing the feel of the mattress.
Comfort / support layers:
* 2.5″ 5-Zone Plush Foam
A zoned comfort foam designed to give a little more contouring where you want it (shoulders/hips) while helping maintain alignment through the middle of the body.
* 0.5″ Latex Lumbar Layer
A targeted lumbar layer intended to help support the lower back so the mattress feels plush, but not like it’s “dropping” you in the middle.
* 1.5″ Pre-Compressed Fiber Support Pad
A transition layer that helps the mattress feel more stable and consistent as you move through the comfort layers into the support system.
Support system: stable, heavy-gauge innerspring support
Under the comfort layers, the Key Largo Pillowtop is built on a heavy-duty, 13-gauge Pocketed innerspring system designed for long-term support and a more consistent feel.
Spring counts vary by size:
* Twin: 462
* Full: 660
* Queen: 805
* King: 1,015
RV Queen availability
In addition to standard sizes, RV Queen (60″ x 75″) is available. If you need a specialty size (like 3/4), ask us what’s currently available for special order.
Who the Key Largo Pillowtop is best for
* Side sleepers and back sleepers
The plush surface helps relieve pressure at the shoulders and hips, while the support system helps keep your back in better alignment.
* Guest rooms and vacation homes
Comfortable enough for everyday use, priced so it makes sense for a second bedroom.
* Couples who want a softer feel
A plush surface that reduces pressure points and feels comfortable across a wide range of body types.
* RV owners (RV Queen size)
A solid upgrade for RV sleep, especially if you want something thicker and more comfortable than a basic camper mattress.
If you sleep on your stomach…
If you’re primarily a stomach sleeper—or you just know you do better on a firmer surface—you’ll typically be happier in the Key Largo Cushion Firm. It provides a firmer feel that helps keep your hips from sinking too far, which is important for stomach-sleep alignment.
Foundation & Base Compatibility – Built to Perform on the Right Support
The Key Largo Pillowtop is designed to perform properly when paired with a solid, supportive base that keeps the mattress evenly supported.
Compatible foundations and bases:
* Standard or heavy-duty foundations
A rigid, all-wood foundation provides even support across the mattress and helps maintain long-term comfort.
* Platform beds
Works well on platform frames with a solid surface or closely spaced, sturdy slats.
* Adjustable bases
Compatible with adjustable bases
