Casper Dream Max Split King Mattress with Head Up Only Base

This mattress is designed with temperature regulation in mind, featuring a top layer of responsive Breathe + Flex Foam. This specialized foam is engineered to enhance airflow and draw heat away from the body. Additionally, the hybrid design uses pocketed coils that naturally provide more ventilation than a solid foam mattress, making it a strong choice for shoppers in warmer climates or those who naturally sleep hot.

This mattress utilizes a sophisticated hybrid construction that combines the contouring support of Align+ Memory Foam with the durability of individually pocketed Flex Coils. The foam layers are specifically engineered to remain flexible and resilient when used with an adjustable foundation, while the coils allow for precise motion isolation and localized support. This combination ensures that the mattress maintains its structural integrity and comfort even when the head of the base is elevated.

Yes. The included RTG Sleep 2900 adjustable base features a "Head Up Only" function, allowing you to elevate the upper portion of the mattress. Based on general sleep expertise, elevating the head can help open airways to reduce snoring and use gravity to prevent stomach acid from rising, which often alleviates symptoms of acid reflux. The wireless remote makes it easy to find your perfect angle for a more restorative night's sleep.

To fully utilize the independent movement of each side, you will need a split king sheet set. These sets typically include two Twin XL fitted sheets, one King flat sheet, and two king-sized pillowcases. Using a standard King fitted sheet would prevent the mattresses from moving independently and could cause damage to the sheets or the adjustable motors.

A split king mattress consists of two separate mattresses on individual bases, making it an ideal solution for partners with varying lifestyle preferences. Because each side is independent, one person can elevate the head of their mattress for activities like reading or watching TV using the wireless remote, while the other side remains flat for sleeping. This setup also provides superior motion isolation, ensuring that one partner’s movements do not disturb the other.

The RTG Sleep 2900 adjustable base is designed to be versatile and can typically fit within most standard King-sized bed frames, including platform, panel, and slat-style beds. However, it is important to ensure your existing frame does not have fixed storage drawers or a solid center foundation that might obstruct the motorized base. Our base has a slim 4-inch profile, allowing it to maintain a low-profile look inside your favorite decorative bed frame.

It is normal for a new high-quality mattress to require a "break-in" period as the foams and coils adjust to your body weight and temperature. According to our expertise, this period usually lasts a couple of weeks. For your peace of mind, Rooms To Go offers a 90-night Mattress Sleep Trial. If you are not satisfied after an initial 30-day adjustment period, you may participate in a one-time exchange to find the perfect fit for your comfort needs.
