Drew & Jonathan Westwater Split King Mattress with Head Up Only Base

This mattress set includes the RTG Sleep 2900 "head up only" adjustable base, which allows you to elevate your upper body at the touch of a button. Raising the head can help open airways to reduce snoring and uses gravity to prevent stomach acid from rising, which is a common recommendation for managing GERD or acid reflux. This customization is particularly effective in a split king configuration, allowing one partner to remain elevated for health reasons while the other sleeps flat.

To take full advantage of the independent head-up features, you will need "Split King" sheets. This typically consists of two Twin XL fitted sheets (one for each mattress) and a single King-size flat sheet and pillowcases. Using two separate fitted sheets is essential; it ensures that when you raise the head on one side, the sheets stay securely in place without tension or popping off the corners.

This mattress is highly optimized for temperature regulation. It features quilted gel foam near the surface to pull heat away from the body, and the TheraLume Memory Foam is specifically formulated to deliver 2.6x longer-lasting cooling than traditional memory foam. This makes it an excellent choice for maintaining a cool-to-the-touch sleep surface, especially in regions where nighttime temperatures remain high.

Yes, this mattress is specifically engineered for compatibility with adjustable motion. It utilizes a sophisticated five-zoned coil system that is flexible enough to contour to the base's elevation while remaining durable. The "extra firm" feel is supported by high-density foams and TheraLume Memory Foam, which is designed to be 2.6x more durable than standard foams, ensuring the mattress maintains its structural integrity even with frequent adjustments.

While a split king consists of two independent mattresses, this model features a robust foam encasement that surrounds the perimeter. This encasement provides a stable, firm edge that helps the two mattresses sit flush against each other, minimizing the "center gap" sensation. For the best experience, we recommend using a split king sheet set or two Twin XL fitted sheets, which allow each side to move independently without pulling the other.

Based on our specialized Mattress Sleep Trial, Rooms To Go offers a 90-night adjustment period for your purchase. We require an initial 30-night "break-in" period to allow your body to acclimate to the extra-firm support and the adjustable base. If you are not satisfied between day 30 and day 90, you are eligible for a one-time exchange to ensure you find the perfect comfort level for your lifestyle.
