Drew & Jonathan Capilano King Mattress with Head Up Only Base

The included RTG Sleep 2900 adjustable base allows you to conveniently raise and lower the head of the bed to find your optimal angle. Elevating the upper body provides ergonomic back and neck support for lifestyle activities like reading, watching television, or relaxing in bed. From a sleep health perspective, sleeping with the head elevated can help open airways to reduce snoring and keep the upper torso angled to ease symptoms of nighttime acid reflux.

The mattress is engineered to significantly reduce motion transfer so partners can sleep without disruption. The individually wrapped coils in the 5-zone TheraWrap system flex independently, preventing movements from echoing across the sleep surface. Combined with dense, motion-absorbing gel and comfort foams, movement from tossing, turning, or getting out of bed remains localized to one side.

This mattress utilizes multi-stage thermal regulation. Near the surface, TheraCool Gel Foam draws excess heat away from your body upon contact, while the advanced 5-Z TheraCool QuadTech Gel Foam is infused with copper, silver, and graphite to keep the mattress cooler, drier, and cleaner. In addition, the iFlex patented hybrid quilt incorporates 1,728 micro-coils directly into the top quilting layer to promote continuous internal airflow and breathability.

The mattress is wrapped in a premium Jacquard fabric woven with Lurex and treated with an Ionexsis antimicrobial finish. This specialized finish actively protects against microbial growth and odor buildup, helping the mattress surface stay clean, hygienic, and fresh over years of nightly use.

The mattress is built around a TheraWrap 934 5-Zone Support System with full foam encasement, delivering targeted, ergonomic reinforcement across five key body zones to maintain proper spinal alignment and relieve pressure on hips and shoulders. Working alongside the support core, layers of 5-Z TheraCool QuadTech Gel Foam and TheraSponse Plush Comfort Foam contour to your body shape while maintaining resilient, durable underlying support.

The king mattress measures 76 inches wide, 79.5 inches deep, and 15.5 inches high. The matching adjustable base measures 75.5 inches wide, 80 inches deep, and 15 inches high, creating a high-profile setup with an overall combined height of roughly 30.5 inches. This mattress and adjustable base set does not require customer assembly.
