The WiseLift 450 is soft, plush and exceptionally comfortable. It lays completely flat, for a comfortable night of sleep regardless of your sleeping position. The chair back and feet operate independently, so find a position just right for you, and sleep through the night. The easy to use remote can memorize your favorite sleep position, and get you there every night. The WiseLift 450 is a favorite with those suffering from sleep apnea or chronic snoring. You’ll get the best sleep whether you lay perfectly flat, or need your head or feet elevated.
