Drew & Jonathan Capilano Split King Mattress With Baselogic Silver

A split king mattress set eliminates motion transfer entirely between partners because the sleeping surfaces and mechanical systems are physically separate. Built with two independent Twin XL mattresses on dual Beautyrest Baselogic Silver adjustable bases, one partner can elevate their head to read or unwind without disturbing someone sleeping flat beside them. If one sleeper shifts positions, tosses, or gets out of bed on a different schedule, the movement stays isolated to their side.

Unlike traditional interconnected innersprings, this mattress uses individually wrapped pocketed coils in its TheraWrap 934 5-zone support system and iFlex quilt. Because each coil responds independently in its own fabric sleeve, the entire core bends fluidly to match the articulation angles of the adjustable base. High-density foam encasement reinforces the mattress perimeter, ensuring the structure maintains its edge support and shape over years of daily adjustment.

Yes. The motorized base allows you to independently raise the head and foot to ergonomic angles that target common sleep disruptions. Elevating the head slightly opens the airway to help reduce snoring and symptoms of acid reflux. Elevating the legs into a slight incline relieves tension on the lumbar spine and promotes healthy circulation, working in tandem with the mattress’s TheraWrap 934 5-zone targeted support system to alleviate lower back pressure points.

This mattress utilizes a multi-stage thermal regulation system. Directly below the breathable Jacquard cover lies TheraCool Gel Foam, which pulls immediate heat away from the body upon contact. Beneath that, 5-Z TheraCool QuadTech Gel Foam incorporates memory foam infused with copper, silver, and graphite—three natural thermal conductors that dissipate heat and wick moisture. Additionally, the iFlex patented quilt incorporates 1,728 micro-coils, promoting continuous internal airflow that prevents warm air from becoming trapped.

The jacquard cover features an Ionexsis antimicrobial finish woven directly with Lurex fibers. This treatment creates an active barrier against odor-causing bacteria, mold, and mildew. By inhibiting microbial buildup deep within the top layers of fabric, the mattress stays fresher, cleaner, and more hygienic over its lifespan.

A split king configuration consists of two individual Twin XL units, each measuring 38 inches wide by 79.5 inches deep. To dress the bed properly, you will need two Twin XL fitted sheets and a standard king-size flat sheet, duvet, or comforter. Because each mattress has a generous 15.5-inch profile, choose fitted sheets with deep pockets (at least 16 to 18 inches) and strong elastic edging to ensure the corners stay securely anchored when the head and foot sections articulate.
