Therapedic Kaanapali King Mattress With RTG-Sleep 3900

Elevating the upper body is a proven method for alleviating these common sleep disruptions. This set includes the RTG-Sleep 3900 adjustable base, which allows you to raise or lower the head of the mattress using a wireless remote. By sleeping at a slight incline, you can help open airways to reduce snoring and utilize gravity to prevent stomach acid from rising, providing a practical, non-invasive solution for better nighttime health.

This mattress features the TheraWrap 5-Zone Support System, which uses individually wrapped coils instead of a linked wire grid. These coils move independently to provide superior motion isolation, meaning you won't feel your partner's movements. The "5-Zone" designation refers to the strategic arrangement of coils to provide targeted support—firmer where you need it for spinal alignment and more forgiving in high-pressure areas like the shoulders and hips.

This mattress utilizes a multi-layered cooling system engineered for advanced thermal regulation. The GlacierTouchCool cover is integrated with Tencel fibers, which are naturally moisture-wicking and more breathable than traditional polyester. Beneath the surface, the 5Z TheraCool QuadTech Gel is infused with copper, silver, and graphite—materials prized for their high thermal conductivity. This allows the mattress to actively draw heat away from the body, maintaining a cooler and drier sleep environment throughout the night.

This King setup (80"L x 76"W) features a single, unified mattress, which is often preferred by couples who value a seamless sleeping surface without the "center gap" found in split-king models. This configuration allows both sleepers to enjoy the full width of the bed together, while the adjustable base provides synchronized head elevation for shared activities like reading or watching TV.

To ensure long-term durability, the mattress is built with a TheraFoam encasement. This high-density foam perimeter reinforces the edges, preventing the "roll-off" feeling and providing a stable surface for sitting. This specific foam edge is designed to be flexible, allowing it to transition smoothly through the base's range of motion without cracking or losing its structural integrity over time.

Eco-Fiber is a high-performance yarn created from recycled water bottles, offering a sustainable alternative to virgin petroleum-based fibers. Beyond its environmental impact, this material is exceptionally resilient and contributes to the mattress's overall breathability and loft. By using recycled water bottles for sustainability, this mattress provides a cleaner, healthier sleep surface without compromising on comfort or longevity.
