Drew & Jonathan Alouette Split King Mattress with Head Up Only Base

The mattress incorporates multiple thermal-regulating layers to keep hot sleepers cool: * **TheraCool Gel Foam:** Draws heat away from the body upon contact for immediate surface cooling. * **5-Z TheraCool QuadTech Gel Foam:** Infused with copper, silver, and graphite to conduct heat away from the core and maintain a cool, dry sleeping environment. * **iFlex Hybrid Quilt:** Incorporates 1,728 micro-coils directly into the quilt layer to promote continuous internal airflow and breathability.

To allow both sides of the base to adjust independently, this setup requires two Twin XL fitted sheets. Because each mattress has a 13.5-inch profile, deep-pocket fitted sheets with strong elastic work best to prevent corners from slipping off during articulation. For top bedding, you can use a single standard King flat sheet, King quilt, or King duvet to create a unified appearance when the bed is flat.

This mattress features a hybrid design combining responsive foams with a TheraWrap 934 5-Zone pocketed coil system and an iFlex quilt containing 1,728 integrated micro-coils. Individually wrapped coils and flexible comfort foams—including TheraCool gel foam and TheraSponse HD extra firm foam—are engineered to articulate smoothly on the adjustable base without crimping, warping, or compromising internal support.

The exterior jacquard fabric is finished with an Ionexsis anti-microbial treatment designed to block bacterial growth and maintain fabric freshness. Beneath the quilt, the 5-Z TheraCool QuadTech foam is infused with copper and silver, which naturally resist microbial buildup and moisture retention over extended daily use.

The split king configuration provides two physically separate mattresses (each measuring 38 inches wide by 79.5 inches long), eliminating direct movement transfer between partners. Additionally, each mattress utilizes a TheraWrap 934 5-zone pocketed coil core with full foam encasement, isolating motion locally so tossing, turning, or different wake-up schedules do not disturb the other sleeper.

The included RTG Sleep 2900 adjustable base allows you to independently raise the head of the bed. Elevating your upper body opens the airways to reduce snoring, uses gravity to keep stomach acid down for relief from acid reflux, and provides ergonomic support for reading, working, or relaxing in bed without neck strain.
