Kingsdown Forestbrook Split King Mattress Set with Head Up Only Base

To ensure your adjustable base functions correctly, you will need a specific "split king" sheet set. This typically consists of two Twin XL fitted sheets (to allow each side to move independently) and one standard King flat sheet and pillowcase set. Based on our expertise with adjustable bedding, we recommend choosing sheets with deep pockets and high-quality elastic to prevent the corners from popping off when the head of the mattress is elevated.

A split king setup is the ultimate solution for couples with different sleep needs. This configuration features two independent Twin XL mattresses, allowing each partner to adjust their head elevation using the RTG Sleep 2900 base without disturbing the other. Additionally, the Kingsdown Forestbrook utilizes a patented motion separation construction. This design provides an undetectable divider that effectively isolates movement, ensuring that if one partner tosses and turns or gets out of bed, the other remains undisturbed.

This mattress is expertly designed for temperature regulation. It features premium Joma Wool, which is naturally moisture-wicking and helps regulate body temperature by pulling heat away from the skin. We also integrate breathable Airflow Latex and gel-infused quilting foams. These materials work together to promote ventilation and provide a cool-to-the-touch surface, making it an excellent choice for maintaining a comfortable sleep environment in humid or warm regions.

While all split kings have a seam, the Kingsdown Forestbrook is hand-tufted to ensure components remain securely in place and don't shift over time. Furthermore, the Full Body Surround Edge Support uses high-density coils along the perimeter of each mattress. This creates a firm, supportive edge-to-edge sleeping surface, minimizing the "canyon" feel and ensuring that the center of the bed remains stable and comfortable for partners.

Yes. Utilizing the included head-up only adjustable base to elevate the upper body can significantly alleviate symptoms of snoring and acid reflux (GERD). By keeping the torso at a slight incline, gravity helps keep airways open and prevents stomach acid from rising. The wireless remote control allows you to find your ideal angle for comfort and health relief with precision.

One of the practical advantages of a split king is its modularity. Because the set consists of two Twin XL mattresses and two separate base components, it is much easier to navigate through tight stairwells, narrow hallways, or small elevators than a traditional one-piece king mattress. This makes it an ideal choice for urban apartment living or older homes with more restrictive architectural layouts.
