Beautyrest Black Series Three Firm Split King Mattress Set with Head Up Only Base

A split king consists of two separate mattresses side-by-side, offering the ultimate solution for partners with different sleep needs. This design virtually eliminates motion transfer between sides and, when paired with the included adjustable bases, allows each person to independently elevate the head of their mattress without disturbing the other. It is a highly effective choice for households where one partner may need to sit up to read or manage health conditions like acid reflux while the other sleeps flat.

Most adjustable bases are designed to fit within standard platform, panel, and slat bed frames. The included base features a 4-inch low-profile design to ensure it integrates seamlessly into your bedroom decor. However, we recommend verifying that your current frame does not have fixed foundations or internal storage drawers that could obstruct the movement of the motorized base.

This mattress utilizes an advanced multi-layered cooling system designed for maximum thermal regulation. The sleep surface features cooling yarn and specialized vertical fibers to pull heat away from the skin instantly. Beneath this, premium memory foam infused with diamond particles acts as a highly efficient conductor, moving heat away from the body to ensure a consistently cool and restorative environment, even in humid or warm environments.

This model features a sophisticated dual-coil architecture. It utilizes Triple-Stranded Pocketed Coil Technology for deep individualized support and motion separation, paired with exclusive 2K Nano Coils. These specialized nano coils provide an extra layer of responsive support that contours precisely to your body’s unique pressure points, providing the targeted relief and durability expected from a premier luxury mattress.

To ensure your total satisfaction, we offer a 90-night Mattress Sleep Trial. Based on our expertise, we recommend an initial 30-night adjustment period to allow your body to adapt to the new support system. If you are not satisfied after this period, you may perform a one-time exchange for a different mattress between 30 and 90 days of delivery. Please note that the mattress must be in good condition and specific exchange fees will apply.

The included RTG Sleep 2900 adjustable base is designed to provide ergonomic support for the upper body. Using the wireless remote, you can conveniently raise or lower the head of the mattress. This feature is particularly beneficial for improving comfort while watching TV or reading, and it can also assist in reducing snoring and improving overall breathing during sleep.
