    Battery Backup
    Every Ultra Comfort power lift chair features an easy-to-use battery backup system in the electrical transformer, which operates on two 9-volt batteries.

    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.

    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.

    Ultracomfort 550 L zero gravity chair

    Bought for my husband. He loves it. The first time he sat in it he fell asleep within 10 minutes. So far so good. I highly recommend.

    Extremely satisfied

    Super well built. Super comfortable and I am extremely satisfied with it.

    Thank you for shopping with us Wayne, we're glad you're enjoying your new UltraComfort UC550 lift chair!


    Don’t know yet ask me later

    Thank you for shopping with us Fred, we really appreciate your business and hope you're enjoying your new UltraComfort lift chair!

    Highly recommend UC550 - Great price!

    This UC550 is the ultimate as is the service from Prime Massage Chairs. Ordered on Monday, delivered Friday. Received personal phone calls with special attention regarding order status. This recliner is a must for all in my age bracket – like 70’s plus. Just think, when I go to the nursing home my UC550 goes with me and my daughter can sleep over in my UltraComfort recliner. I get such good naps and night-time sleeping any time of the day. We in the 70-80’s don’t sleep straight through so we get out of bed and complete our night’s sleep in the UltraComfort. Don’t overlook the stuffing in the 3 pillows on the back which can be easily adjusted through the convenient zippers. I can get the exact fluffiness for rest and sleep. The price is as perfect as it can get. Before I found primemassagechairs.com, I had purchased a UC550 medium elsewhere for $500 more, which was even then a reduced price as listed on that .com site. Another reason I chose this UC550 is to avoid the over-stuffed arms, which make the chair wider while still getting the stuffed back. The 3 pillows is beneficial for the lumbar support. This chair is easy to get into the house following on curb delivery. Before bringing through the door, connect to electricity and lower the back. Easily slips through the door. This is great price, great chair, great service. I highly recommend as an investment for the age when hip and knee surgeries occur and home is away from home as the recliner moves with owner. Visitors can cat nap or sleep overnight.

    Thank you Marilyn for your review, it means a lot to us to know that you're getting so much use out of your new lift chair. We hope you and your family get many years of enjoyment and thank you for shopping with us!

    Lift chair

    WE are really happy with the quality of our chair. Only wish that along with being a great lift chair, message and heat were available in this style... Ideally, a usb jack for recharging would be nice and something to think about in the future.

    Over all, very nice chair, great people to work with.

    Thank you Cheryl, we really appreciate your business!
