Therapedic Ledo King Mattress with RTG-Sleep 3900

This mattress utilizes a sophisticated multi-layered cooling strategy that is particularly effective in warm or humid climates. The surface features GlacierTouchCool fabric blended with Tencel, which provides an immediate "cool-to-the-touch" sensation and superior moisture-wicking properties. Directly beneath the surface, the 5Z TheraCool QuadTech Gel is infused with copper, silver, and graphite—materials known for their high thermal conductivity—to actively draw heat away from the body. Additionally, the dual-coil construction promotes continuous airflow through the mattress core to prevent heat from becoming trapped.

The included RTG-Sleep 3900 adjustable base allows you to independently raise the head and foot of the mattress via a wireless remote. Elevating the head can help open airways to reduce snoring and alleviate symptoms of acid reflux (GERD) by preventing stomach acid from rising. For lower back relief, many users utilize the base to achieve a "Zero-Gravity" position—elevating the legs slightly above the heart—which helps decompress the spine and reduce pressure on the lower lumbar region.

The TheraWrap 5-Zone Support System provides advanced, targeted pressure relief by varying the tension of the individually wrapped coils across five distinct horizontal sections. This design offers firmer support for the heavier hip and torso areas while allowing for more cushion and "give" at the shoulders and knees. This targeted approach helps maintain a neutral spine position throughout the night, which is critical for preventing morning aches and pains.

Yes, this hybrid mattress is specifically engineered for full compatibility with adjustable foundations. By combining a 1728 DuraCoil Micro Coil system and individually wrapped TheraWrap coils with flexible TheraSense comfort foams, the mattress is designed to contour smoothly to the angles of the RTG-Sleep 3900 base. This flexibility allows the mattress to bend without compromising the structural integrity of the coil systems or the long-term support of the mattress.

The Eco-Fiber used in this mattress is a high-performance yarn crafted from recycled water bottles. By repurposing post-consumer plastic into durable textile components, this material reduces environmental waste without sacrificing the mattress's comfort or durability. This fiber layer provides a resilient, sustainable foundation that works in tandem with the comfort foams to provide long-lasting pressure relief.

The choice depends on your specific lifestyle and sleep preferences. The standard King mattress provides a unified, continuous sleeping surface, which is often preferred by couples who value sleeping close together without a center seam. However, if you and your partner have vastly different needs—such as one person needing to sleep elevated for medical reasons while the other sleeps flat—the Split King variation (composed of two separate Twin XL units) allows each person to customize their side of the bed independently.

This mattress features a comprehensive TheraFoam encasement, a high-density foam border that reinforces the perimeter of the coil system. This specialized edge support prevents the "roll-off" sensation and expands the usable sleeping surface to the very edge of the bed. Furthermore, it creates a stable, firm surface for sitting on the side of the bed, making it easier to transition in and out of the mattress, especially when it is in an elevated position.
