Drew & Jonathan Capilano King Mattress With Baselogic Silver

The mattress provides high motion dampening by isolating movement at the coil level. Each of the 934 pocketed coils in the TheraWrap core compresses individually under localized pressure rather than transferring vibration across the entire sleep surface. In addition, the upper layers of TheraSponse Plush Comfort Foam and dense memory foam absorb surface energy, minimizing sleep disruptions when a partner shifts positions or gets out of bed.

This standard king set features a continuous 76-inch by 79.5-inch mattress that moves as a unified surface, making it ideal for couples who prefer an unbroken bed without a center gap for cuddling. For partners with differing schedules or preferred sleeping angles, this model is also offered in a split king configuration, which utilizes two separate mattresses and independent bases so each sleeper can adjust their elevation individually.

This mattress uses an active heat-dissipating system built across multiple layers. The surface features an iFlex quilt with 1,728 micro-coils that allow continuous airflow, paired with TheraCool Gel Foam to quickly draw warmth away from the body. Directly beneath, 5-Z TheraCool QuadTech Gel Foam is infused with copper, silver, and graphite—minerals known for natural thermal conductivity that disperse excess heat and resist moisture buildup throughout the night.

Yes. This mattress is engineered specifically for motorized bases using a TheraWrap 5-Zone Support System composed of 934 individually pocketed coils rather than a rigid connected wire grid. Paired with an iFlex quilt featuring 1,728 flexible micro-coils and responsive contouring foams, the mattress smoothly flexes along the contours of the Beautyrest Baselogic Silver base without buckling, bunching, or compromising internal support.

Together, the 15.5-inch thick mattress and 16-inch adjustable base yield an overall profile height of roughly 31.5 inches from the floor. Because of the substantial 15.5-inch mattress depth and the dynamic movement of the adjustable base, standard king fitted sheets with deep or extra-deep pockets (rated for up to 18 inches) and strong elastic edging are recommended to prevent the corners from popping off during articulation.

The included Beautyrest Baselogic Silver base allows you to independently raise the head and foot sections using an electronic remote. Raising the head helps open the airway to ease snoring and symptoms of acid reflux, while elevating the legs relieves tension across the lumbar spine and improves lower-body circulation. These adjustments work in tandem with the mattress's five ergonomic support zones, which deliver firmer lumbar reinforcement and tailored pressure relief under the shoulders and hips.
