Correct Comfort by Sealy Northgate Split King Mattress with Ease

A split king mattress is the ultimate solution for partners with different sleep preferences or schedules. Because this set consists of two independent mattresses, each sleeper can use the Sealy Ease 4.0 adjustable base to find their perfect position without disturbing the other. This setup virtually eliminates motion transfer, meaning one person can adjust their head height for reading or snoring relief while the other remains completely flat and undisturbed.

Yes, this mattress features Surface-Guard Technology™ integrated into the cover. This antibacterial treatment is designed to protect the mattress from common household allergens and odors caused by bacteria and microbes. This helps ensure your sleep surface remains fresh and hygienic over years of use, which is a hallmark of Sealy’s commitment to high-quality bedding standards.

This mattress utilizes a sophisticated layering system for long-term durability and pressure relief. The top layer of ComfortSense™ Premium Cool Gel Memory Foam conforms to your body's unique curves to relieve pressure points in the shoulders and hips. Supporting this is the SealySupport™ Gel Foam, a high-density foundation layer that ensures the mattress maintains its structural integrity and provides the necessary back support for all sleep positions.

While a split king consists of two separate mattresses to allow for independent movement, the gap is designed to be minimal. When both sides are in the flat position, the mattresses sit flush against each other. For those concerned about the seam, our experts recommend using high-quality Twin XL fitted sheets to keep each mattress secure. The included Sealy Ease adjustable base is also designed to keep the mattresses aligned, preventing them from sliding apart during use.

The Sealy Ease 4.0 base provides a customizable sleep experience via a wireless remote. You can independently adjust the head of the mattress up to 60 degrees and the foot up to 40 degrees. This is particularly beneficial for lifestyle needs such as watching TV in bed, as well as health concerns like acid reflux, poor circulation, or lower back pain, as it allows you to find an ergonomic "Zero-G" style position.

To ensure the best fit and allow the adjustable base to move freely, you will need a Split King sheet set. This typically includes two Twin XL fitted sheets (one for each mattress) and a single King-size flat sheet and pillowcase set. Based on our expertise with adjustable beds, we recommend sheets with deep pockets and "secure-fit" elastic to prevent the corners from popping off when the head or foot of the bed is elevated.

This mattress is engineered with a dual-action cooling system ideal for warmer climates or those who tend to overheat at night. The Stretch-Knit Cover features SealyChill™ technology to wick away moisture and heat instantly. Below the surface, ComfortSense™ Premium Cool Gel Memory Foam works to disperse body weight and heat, promoting better airflow than traditional memory foams to maintain a consistently cool sleeping environment.
