Beautyrest Series Three Mattress

A Split King consists of two Twin XL mattresses and two independent adjustable bases. This allows you and your partner to adjust the head position of your side of the bed individually without disturbing the other person.

Diamond particles are highly conductive, meaning they help draw heat away from your body and dissipate it through the mattress surface. This prevents heat buildup, keeping the sleep surface cooler throughout the night.

The 2K Nano Coils are smaller, micro-coils that provide an extra layer of individualized support and contouring. They work in tandem with the base pocketed coils to enhance pressure relief and responsiveness.

The mattress itself is 16.75 inches thick. When placed on the RTG Sleep 2900 base, the total height will depend on the leg height you choose for the base, but you should expect a substantial, high-profile sleep setup.

Yes, the plush pillowtop combined with the specialized foam and ventilated latex layers is designed to provide deep pressure relief. This is particularly beneficial for side sleepers who need extra cushioning for their shoulders and hips.

Yes, all foams used in the Beautyrest Black Series Three are CertiPUR-US certified. This means they are made without ozone depleters, mercury, lead, or other heavy metals and have low VOC emissions for better indoor air quality.
