Tuft & Needle TN3.1 Split King Mattress Set with Head Up Only Base

To allow for the independent movement of each side, you will need a split king sheet set, which typically includes two Twin XL fitted sheets and one King-size flat sheet. Because these mattresses feature a 12.5-inch profile and a reinforced seating edge, we recommend choosing high-quality, deep-pocket sheets with strong elastic borders to ensure the bedding remains secure and tucked in while the head of the mattress is elevated.

This hybrid mattress is specifically engineered to balance durability with the flexibility required for motion. It features 875-density individually wrapped coils that provide responsive pressure relief and a durable "bounce-back" support system. Unlike traditional innersprings, these independent coils are designed to bend seamlessly with the adjustable base, ensuring the mattress maintains its structural integrity and support even with frequent articulation.

Yes. Elevating the head of the mattress is a widely recognized method for alleviating snoring, symptoms of acid reflux (GERD), and sleep apnea by improving airflow and reducing esophageal pressure. The included RTG Sleep 2900 adjustable base allows you to use a wireless remote to find the precise angle of elevation needed to manage these conditions effectively, providing a customizable, non-invasive sleep solution.

A split king mattress set consists of two separate Twin XL mattresses, allowing each sleeper to customize their environment independently. In this specific set, the included adjustable bases allow you and your partner to raise or lower the head of your respective mattresses without disturbing one another. This configuration is an ideal solution for couples with different sleep schedules or those who enjoy individualized positions for reading or watching television in bed.

While a seam is necessary for independent movement, this mattress is constructed with a foam-encased seating edge that provides corner-to-corner support. This reinforced border is designed to keep the mattresses stable and flush against each other, significantly reducing the "gap" feel common in split configurations. Our expertise suggests that proper alignment of the two adjustable bases during setup is the most effective way to maintain a consistent, unified sleeping surface.

This mattress is specifically outfitted with advanced cooling technologies to combat heat retention. It features a cool-to-the-touch cover paired with T&N AdaptiveCool gel foam technology, which is engineered to absorb and dissipate body heat. This combination is particularly effective for sleepers in warmer or humid climates, as it helps maintain a regulated temperature and prevents the "sleeping hot" sensation often associated with standard foam mattresses.

The "head-up only" designation refers to the specific articulation of the RTG Sleep 2900 base, which focuses on raising the upper portion of the mattress. Using the wireless remote, you can adjust the head of the bed to your desired angle for improved breathing or comfort while sitting up, while the foot of the bed remains in a flat, supportive position. This provides the essential benefits of an adjustable bed with a streamlined, easy-to-operate design.
