    StellarComfort Positioning
    StellarComfort positioning technology allows for a greater range of positions at the touch of a button. These positions may help improve circulation, relieve back pressure and enhance comfort.

    Battery Backup
    Every UltraComfort power lift chair features an easy-to-use battery backup system in the electrical transformer, which operates on two 9-volt batteries. In the event of a power failure, the battery system will raise the chair from the reclined to the seated position one time. The batteries should be replaced after one use

    SmartTek Diagnostic System
    The SmartTek Diagnostic System is there to assist you in finding any issues fast. This system will notify you if there are any electrical malfunctions, and will help technicians diagnose the issue quickly over the phone.

    Enjoy 3 Types of Comfort Control:
    Total, Position, and Custom

    Total Control
    The Recline button raises your legs and feet and has the capability to take you to the zero gravity position. The Lift button raises the chair to an ideal standing position, saving your joints from unneeded stress. Only two buttons are needed to experience our patented positioning technology.

    Position Control
    Use these four programmable positioning buttons to customize your comfort.

    • Sit brings you to a neutral seated position with the back upright and footrest closed.
    • TV keeps the back upright, but raises the seat box and footrest for relaxation of your lower back and legs.
    • ZG or “zero-gravity” is a level recline position that supports your legs and evenly distributes your weight providing back relief and pressure-free relaxation.
    • Sleep takes you to a lay-flat recline position allowing you to stretch out for a peaceful rest.
    • P initiates any programming features and lock capabilities.

    Custom Control
    Four arrow buttons move the chair back and footrest independently allowing for infinite positioning and optimal comfort. Achieve the Trendelenburg position by holding the “down” arrow button that operates the back while reclined in the zero gravity position. This can promote circulation and provide a satisfying stretch to your lower back. (Consult your physician before trying this position.)

    Ergonomic Hand Control Design 
    The shape, as well as the finger groove on the back, makes it easier to hold.

    Button Display and Positioning 
    Simple button layout takes the guesswork out of operating a StellarComfort chair.

    Programmable Positioning Buttons 
    All four position control buttons are programmable for customizable comfort.

    Lock Functions 
    Partial and total lock functions limit or restrict hand control usage for safety and convenience.
