Therapedic Darlington King Mattress with Head Up Only Base

This mattress set includes the RTG Sleep 2900 adjustable base, which allows you to elevate the head of the bed using a wireless remote. According to our sleep experts, elevating the torso can significantly improve sleep quality by helping to reduce snoring and alleviate the symptoms of acid reflux (GERD). It also provides a more ergonomic position for reading or watching television in bed, reducing strain on the neck and lower back.

Yes, this mattress is engineered specifically for temperature regulation, making it an excellent choice for hot sleepers or those living in humid, coastal climates. The GlacierTouch fabric is cool-to-the-touch, providing immediate thermal relief. Furthermore, the integrated Fit Hypergraph with Copper wicks away excess heat and moisture while providing antimicrobial properties to keep the sleep environment fresh and odor-free.

This adjustable base is designed with a low-profile 4-inch height, allowing it to fit seamlessly within most standard panel, slat, or platform bed frames. Because it replaces the need for a traditional box spring, it is a practical upgrade for those who wish to keep their current bedroom aesthetic while gaining the health benefits of an adjustable sleep system.

The standard King set moves as a single unit, meaning both partners are raised or lowered together—ideal for couples who share the same sleep schedule and positions. The Split King version consists of two separate Twin XL mattresses and bases placed side-by-side. This configuration is the ultimate solution for partners with different preferences, as it allows each person to adjust their side independently without disturbing the other.

The Darlington mattress utilizes a TheraCoil V-Coil innerspring system, designed for exceptional flexibility on an adjustable base without sacrificing durability. This is paired with TheraSponse Foam, a high-performance material known for its resilience and ability to maintain a supportive sleep surface over many years. Additionally, the reinforced edge construction expands the usable sleep surface and prevents sagging when sitting on the side of the bed.

We provide a 90-night Mattress Sleep Trial to ensure you are completely satisfied with your purchase. Based on our expertise, we recommend an initial 30-night adjustment period to allow your body to acclimate to the new support system. If you are not satisfied after that period, you may participate in a one-time exchange for a different mattress of equal or greater value between days 30 and 90 of delivery.
