Kingsdown Smart Match 2.0 King Mattress with RTG-Sleep 5900

The RTG Sleep 5900 adjustable base is designed to be versatile. In many cases, it can be placed inside an existing bed frame, provided the frame does not have restrictive slats or a built-in platform that interferes with the base's clearance. If you are matching this to a traditional bed, our experts recommend ensuring the interior dimensions of your frame can accommodate the 76"w x 80"l footprint of the base.

The included RTG Sleep 5900 adjustable base allows for precise positioning of both the head and feet via a wireless remote. For those dealing with snoring or obstructive sleep apnea, elevating the head can help open airways. Similarly, sleepers with acid reflux (GERD) often find relief by using the base to maintain a slight incline, using gravity to prevent stomach acid from rising, which is a significant lifestyle improvement over using unstable foam wedges or extra pillows.

This mattress utilizes an advanced thermal management system designed to keep sleepers comfortable throughout the night. The Tri-Tech gel memory foam is infused with copper, silver, and graphite—highly conductive materials that actively draw excess heat away from the body. Additionally, the cooling cover is woven with silk and wool fibers to wick away moisture, making it an excellent choice for individuals in warmer climates or those who tend to sleep hot.

Yes, this mattress is specifically engineered for motion isolation. It features an undetectable divider that separates both sides of the mattress, effectively absorbing energy and preventing movement from traveling across the bed. Combined with the individually wrapped coils, this design ensures that when one partner moves or exits the bed, the other remains undisturbed.

For this standard King size set, you can use high-quality King-sized sheet sets. However, we recommend choosing "Deep Pocket" fitted sheets or those with heavy-duty elastic bands. Because the mattress is 16 inches thick and moves with the adjustable base, standard sheets may slip off the corners; deep-pocketed options ensure the fabric remains secure even when the head or foot of the bed is fully elevated.

Unlike traditional interconnected springs, this mattress features hundreds of individually wrapped coils that move independently to contour to your body's specific shape. To address common pressure points, the system is engineered with targeted support, utilizing firmer coils in the center third of the mattress to reinforce the lower back and promote proper spinal alignment.
