Therapedic Kaanapali Split King Mattress With RTG-Sleep 3900

Yes. The included RTG-Sleep 3900 adjustable base allows you to raise the head of the mattress to your preferred angle. Elevating the upper body is a common recommendation for opening airways to reduce snoring and using gravity to alleviate the symptoms of acid reflux (GERD). For physical support, the TheraWrap 5-Zone Support System uses individually wrapped coils to provide targeted pressure relief to the spine and joints.

This mattress is engineered specifically for temperature management. It features GlacierTouch fabric with Tencel, which is cool to the touch and naturally breathable. Internally, it utilizes 5Z TheraCool QuadTech Gel—an advanced infusion of copper, silver, and graphite—to actively dissipate body heat. This combination helps maintain a cooler, drier, and more hygienic sleep environment, which is particularly beneficial in warmer geographic regions.

To allow for the independent movement of each side, we recommend using a split king sheet set. These sets typically include two Twin XL fitted sheets and one King-sized flat sheet. Using separate fitted sheets ensures that when you adjust the head of your mattress, the fabric stays securely tucked in and doesn't pull against your partner’s side of the bed.

Yes, this mattress incorporates Eco-Fiber, a sustainable yarn manufactured from recycled water bottles. This material choice helps reduce plastic waste while maintaining the durability and comfort expected from a high-quality hybrid mattress, making it an excellent option for environmentally conscious shoppers.

This mattress is designed with TheraFoam encasement, a premium high-density foam border that provides exceptional edge support. This reinforcement prevents the edges from sagging over time and ensures a stable, smooth transition when you are sitting on the side of the mattress or getting out of bed in the morning.

A split king setup is the ultimate solution for couples with different sleep schedules or comfort needs. Because it consists of two independent mattresses and two separate bases, each person has full control over their side. For example, one partner can use the wireless remote to raise the head of the mattress to read or watch TV while the other partner sleeps flat, ensuring completely undisturbed sleep for both.

A split king is an ideal choice for urban living or homes with challenging layouts. Unlike a standard king mattress, which is one large, rigid piece, a split king consists of two Twin XL mattresses (38" x 80" each). This modular design makes it significantly easier to maneuver through narrow staircases, small elevators, and tight doorways during delivery and setup.
