Beautyrest Harmony Lux Medium Split King Mattress with Head Up Only Base

A reinforced edge is a critical feature for both durability and comfort. It prevents the mattress from sagging or feeling unstable when you sit on the side or sleep near the perimeter. In an adjustable system, this edge construction ensures that the mattress maintains its structural integrity and provides a consistent sleep surface even as the base transitions through different positions.

A split king mattress provides the ultimate level of personalized comfort for partners with different sleep preferences. Because the mattress is composed of two independent Twin XL units, each person can adjust their side's elevation without affecting the other. This design also serves as a natural barrier to motion transfer, ensuring that one partner's movements—or adjustments to their base—don't disturb the other's rest.

The motorized base included with this set is designed for quiet and smooth operation. The wireless remote allows you to make precise adjustments to your position without the disruptive mechanical noise found in older systems. This allows one partner to transition to a seated or elevated position without waking the other, making it an ideal choice for households with different sleep schedules.

To allow each side of the mattress to move independently, a split king requires a specific sheet configuration: two Twin XL fitted sheets and one standard King-sized flat sheet and comforter. Based on our expertise, we recommend choosing fitted sheets with deep pockets and high-quality elastic to ensure the fabric stays securely in place while the head of the mattress is elevated.

Yes, this mattress is specifically engineered for temperature regulation. It features RightTemp Wave Foam and uniquely engineered cooling technologies designed to draw heat away from the body. These advanced materials, combined with sustainable fabric technology, promote airflow and help maintain a comfortable sleeping temperature, which is especially beneficial for sleepers in warmer or humid climates.

Elevating the head of the mattress can be a highly effective way to address issues like snoring and acid reflux. By using the included wireless remote to raise the head of the bed, you help keep airways open and use gravity to prevent stomach acid from traveling upward. This specific base is designed for "head-up" functionality, providing targeted relief and a comfortable position for reading or watching TV in bed.
