Drew & Jonathan Maple Ridge Split King Mattress With Baselogic Silver

Proper spinal alignment is achieved through the TheraWrap 934 5-Zone Support System, which varies coil tension across five ergonomic zones to deliver firmer support where the torso needs it and softer cushioning beneath the shoulders and hips. Above the coils, TheraSense self-adjusting comfort foam responds to your body shape to alleviate pressure points. Pairing these internal zones with the Baselogic Silver base allows you to elevate the head and feet into an ergonomic zero-gravity posture, taking direct pressure off the lower lumbar spine.

Yes. A one-piece standard king mattress and base can be difficult to maneuver around tight corners, through standard doorways, or up narrow stairwells. This split king setup arrives as two separate modular Twin XL mattresses (38"W x 79.5"D x 15.5"H each) and two Twin XL bases (38"W x 80"D x 16"H each), making transportation through tight apartment entryways, hallways, and multi-story homes significantly easier during delivery and room setup.

A split king setup consists of two independent Twin XL mattresses (each 38"W x 79.5"D) on two separate adjustable bases (each 38"W x 80"D). This allows each partner to independently raise the head or foot to their preferred position—ideal if one person wants to sit up to read while the other sleeps flat. Furthermore, the complete physical separation of the two sleep surfaces, combined with pocketed coils and TheraSense contouring foam, virtually eliminates motion transfer so a partner getting in or out of bed does not disturb the other.

This mattress is engineered specifically for articulated movement using a multi-layer hybrid build. It combines an iFlex patented hybrid quilt featuring 1,728 flexible micro-coils with a TheraWrap 934 5-zone individually wrapped coil system. Because the coils are independently encased rather than linked with rigid wire, they bend smoothly with the Baselogic Silver base without pinching, kinking, or compromising structural integrity. Foam encasement around the perimeter also maintains edge stability whenever the head or foot is raised.

Because this setup uses two separate Twin XL sleep surfaces, you will need a split king sheet set, which typically includes two Twin XL fitted sheets and a standard King flat sheet and comforter. Because each mattress has a substantial 15.5-inch profile height and articulates frequently, we recommend choosing deep-pocket fitted sheets rated for 16 to 18 inches with full-perimeter heavy-duty elastic or corner straps. This extra depth prevents the sheets from popping off the corners when the base elevates.

The mattress incorporates multiple cooling and moisture-managing layers designed to dissipate trapped body heat. The surface is treated with TheraCool Gel Foam for an instant cooling sensation, while the underlying 5-Z TheraCool QuadTech memory foam is infused with copper, silver, and graphite—minerals selected for their natural thermal conductivity to draw heat away from the body. Beneath that, the 1,728 micro-coils in the hybrid quilt promote constant internal airflow, and the jacquard cover features an Ionexsis anti-microbial finish that keeps the sleep environment fresher in warmer, high-humidity environments.
