Drew & Jonathan Alouette King Mattress with Head Up Only Base

The mattress provides high motion isolation to prevent sleep disturbances between partners. Because the 934 TheraWrap coils are individually encased in fabric pockets, each spring reacts independently to pressure rather than transferring movement across the entire sleep surface. Additionally, thick layers of TheraSponse HD comfort foam and QuadTech gel foam absorb kinetic energy from tossing and turning.

This mattress incorporates multiple temperature-regulating components to keep hot sleepers comfortable. The top layer features Jacquard fabric with an Ionexsis anti-microbial finish paired with TheraCool Gel Foam, which pulls heat away from the body upon contact. Beneath that, the iFlex Hybrid Quilt uses 1,728 micro-coils that promote active airflow through the top layers, while 5-Z TheraCool QuadTech Gel Foam is infused with copper, silver, and graphite to continuously dissipate excess heat and manage moisture throughout the night.

This mattress utilizes targeted zonal support through both its foam and coil layers. The TheraWrap 934 innerspring unit and the 5-Z TheraCool QuadTech Gel Foam are structured with five distinct support zones. These provide reinforced resistance under the heavier lumbar and hip regions to keep the spine aligned while offering softer contouring at the shoulders and knees to alleviate joint pressure.

The included RTG Sleep 2900 adjustable base allows you to smoothly elevate the head of the bed. Raising the upper torso opens up airways to help reduce snoring and symptoms of acid reflux or GERD. It also provides ergonomic support for reading, watching TV, or working on a laptop without stacking pillows or straining your neck and lower back.

The king mattress measures 76 inches wide by 79.5 inches deep with a 13.5-inch profile height. The accompanying head-up adjustable base measures 75.5 inches wide by 80 inches deep and 15 inches high, resulting in a total combined sleep surface height of approximately 28.5 inches. The base is sized to fit within most standard king-size bed frames and freestanding headboards.

The mattress is specifically engineered for adjustable articulation. It uses a TheraWrap 934 5-Zone Support System featuring individually pocketed coils rather than a rigid, interconnected innerspring unit. Combined with the flexible iFlex micro-coil quilt and durable TheraSponse HD foam, the internal components flex naturally with the base's movement without warping or compromising structural integrity.
