    Quality Craftsmanship
    Featuring a Northern Maple Hardwood Frame on all Stress Points. The UC550-M also has been "Double Doweled at the Stress Points, Reinforced Mitre Blocks, and is Stapled and Glued for maximum durability.

    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. Experience the difference of this unique motion technology.

    Stellar Comfort Positioning

    If you like the features of this chair but need a smaller version, you'll want to look at the UC550-JPT. If you need a larger version of this chair, please see the UC550-Large.

    Battery Backup
    Every UltraComfort lift and recline 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.

    Battery Backup

    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.

    3 Types of Comfort Control:

    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.

    Remote Control

    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.

    Lift Frame, Chair Frame, Recline Bar, and Scissor Mechs have a Lifetime Warranty. 3 Year Warranty on Electrical Parts. Prorated 4-7 years on Electrical Parts. 1 Year Warranty on Mechanical Labor. 1 Year Warranty on Electrical Labor.

    Great Chair!

    This is the second chair of the same model and style. Works well for our patient and he literally lives in this chair.

    Thank you Jim for your review, we're glad your patient is enjoying his new lift chair!

    Cincinnati Review

    I own a Large Ultra Comfort Zero Gravity Lift Chair also. Both are comfortable however the Medium chair rubs between the seat cushion and the inside of the arms so that it makes a lot of noise every time the chair is in motion. This did not happen with the Large size chair.

    Feeling good!!!!!!!!!!!!!!!


    Thank you for the review Keith, and we're glad you're feeling good!!


    Great chair. Comfortable and supportive. I want to buy another one for my husband.

    Thank you for the review Karen and we're glad you're enjoying your new Ultra Comfort lift chair! When you're ready to order one for your husband just give us a call. Thank you for your business, we really do appreciate you.
