Drew & Jonathan Alouette Split King Mattress With Baselogic Silver

The included Beautyrest Baselogic Silver base features motorized head and foot articulation controlled via remote. Raising the head section slightly helps open the sleeper's airways to reduce snoring and alleviate nighttime acid reflux (GERD) by preventing stomach acid from traveling upward. Simultaneously elevating the foot section takes pressure off the lower lumbar spine and pelvic region, promoting lower-body circulation and easing pressure points along the lower back and hips.

A split king sleep system consists of two separate Twin XL mattresses, each measuring 38 inches wide, 79.5 inches deep, and 13.5 inches high. To allow each sleeper to adjust their side independently, you will need two separate Twin XL fitted sheets. Given the 13.5-inch mattress profile, look for fitted sheets with deep pockets (15 inches or deeper) and heavy-duty corner elastic so the corners do not pop off when the head or foot is elevated. You can then finish the bed with a standard King flat sheet, quilt, or duvet across the top to create a seamless, unified look when both sides are flat.

This mattress is an advanced innerspring hybrid engineered specifically for articulation. Its foundation utilizes the TheraWrap 934 5-Zone Support System featuring individually wrapped coils encased in high-density foam, complemented by an iFlex patented hybrid quilt containing 1,728 flexible micro-coils. Because the coils are individually pocketed rather than tied together with rigid continuous wire, each spring independently contours and bends with the movement of the adjustable base without warping, binding, or compromising structural support over time.

This split king configuration provides near-total motion isolation by physically separating the sleep surfaces into two independent Twin XL mattresses on two separate adjustable bases. Any movement from tossing, turning, or getting in and out of bed stays isolated to that individual mattress. Furthermore, the internal construction incorporates TheraSponse HD extra-firm comfort foam and individually wrapped TheraWrap pocketed coils, which absorb localized kinetic energy and prevent vibrations from traveling across the bed.

Yes, the split king format is an ideal solution for homes with difficult architectural access, such as older multi-story homes, narrow interior staircases, or tight apartment elevator banks. Rather than navigating a rigid, full-size one-piece King mattress, the set is delivered as two independent Twin XL mattresses (38"W x 79.5"D x 13.5"H each) and two separate Twin XL base units (38"W x 80"D x 16"H each). These modular dimensions maneuver easily around tight corners and through standard 30- to 36-inch interior doorways without risking damage to walls or door frames.

The mattress incorporates a multi-layer cooling system designed to actively disperse trapped body heat and improve ventilation. The sleep surface features TheraCool Gel Foam for immediate cooling upon contact, while the quilt’s 1,728 micro-coils promote continuous airflow through the top layers. Beneath that, a five-zone TheraCool QuadTech Gel Foam layer utilizes memory foam infused with copper, silver, and graphite—minerals naturally prized for thermal conductivity that channel excess heat away from the body to keep the sleep environment cool and dry.
