Enjoy simple sophistication with a wired remote to raise and lower your headrest. The Quest 1.0 Adjustable Base is fully equipped with silent−drive motors and energy−efficient technology, delivered to you at an attractive price point. For partnered sleepers who want to further customize their sleep, consider a split king adjustable base. Two Twin XL bases are the exact same size as a regular king, but allows the sleeper the ability to control the positioning of their side of the bed. A semi-recumbent pose means that the head and upper body are slightly elevated throughout the night. Studies have shown that sleeping in this position has proven health benefits such as helping to combat sleep apnea and breathing issues related to COPD, reduce snoring, and alleviate back pain, post nasal drip, heartburn, acid reflux and more.
