Helix Midnight Elite Split King Mattress Set with Head Up Only Base

While the split king configuration is designed to provide each sleeper with independent control over their head elevation, it does not have to sacrifice intimacy. This specific model features a reinforced edge border style, which provides extra stability at the mattress perimeter. This ensures that when the two mattresses are flush, the center seam remains supportive rather than sagging. For those concerned about the "gap," our experts often recommend high-quality king-sized top sheets and comforters to maintain a unified look and feel while the base is in the flat position.

The cooling in this mattress is a core feature of its design. It features GlacioTex™ Elite technology, which is a specialized fabric engineered to be highly conductive, quickly pulling excess heat away from the body. This is particularly beneficial in humid or warm climates, as it works in tandem with the breathable microcoil layer to regulate your core temperature throughout the night, ensuring you don't wake up overheated as the memory foam contours to your body.

This set includes the RTG Sleep 2900 "Head Up Only" adjustable base, which is a powerful tool for improving sleep health. By using the wireless remote to elevate the head of the mattress, you can utilize gravity to keep airways open—a common solution for reducing snoring and the symptoms of mild sleep apnea. Furthermore, sleeping at a slight incline is a medically recognized method for preventing stomach acid from rising, providing significant relief for those with GERD or chronic acid reflux.

Absolutely. This mattress is specifically engineered for compatibility with adjustable motion. It utilizes a sophisticated hybrid design consisting of five high-density foam layers and a microcoil comfort layer. These materials are inherently flexible and resilient, allowing the mattress to contour perfectly to the base's position without causing permanent creasing or compromising the internal zoned coil support system.

To allow the two sides of the mattress to move independently, you will need two separate Twin XL fitted sheets. However, you can still use a standard King-sized flat sheet, quilt, or duvet over the top to keep the bed looking like a traditional King. Because this mattress features a 15-inch profile and a 2-inch plush pillow top, we recommend choosing "deep pocket" Twin XL sheets to ensure they stay securely fastened to the corners during adjustment.

One of the greatest logistical advantages of a split king is its maneuverability. Unlike a standard solid King mattress, which can be nearly impossible to fit through tight stairwells or narrow apartment hallways, this set is delivered as two separate Twin XL units. This modularity makes it significantly easier to navigate into smaller urban living spaces or older homes with challenging layouts without the risk of damaging the mattress or your walls.
