UltraComfort StellarComfort UC550-L Power Lift Chair

The UltraComfort StellarComfort UC500-L power lift chair is the only large size lift chair within the StellarComfort collection. Ideal for users between 5’11” and 6’2”, this lift chair can handle up to 375 lbs. Even though it’s a larger chair it still holds the same style features as the smaller versions including the three pillow waterfall backrest. With a StellarComfort collection lift chair you get a full range of positions that can be programmed into the remote. Start off with one of the four positions and adjust it so its perfect for you and then reprogram the button to take you to that position with every use. This is just one way that UltraComfort lift chairs cater to your needs and preferences. Upgrade the capabilities of your lift chair with massage and heat therapy to ensure maximum relief every time you use it. These systems do add some additional handling time before shipment so the additional components can be installed, but you will be able to add massage and heat therapy to your everyday life. Learn more below.

Plus, UltraComfort is now offering a lifetime warranty on the UltraPlush Brisa fabric. This warranty protects against cracking, fading, or delamination, as long as regular use is maintained. This fabric is now available in 10 colors.

From the Manufacturer

Designed to fit people from 5’11” to 6’2″ with a 375 lb. weight capacity, the UC550-L has a three-pillow waterfall backrest. Each pillow has a convenient zipper on the under side to access the Dacron® fill and allow you to customize your own comfort, adding or removing the Dacron® to provide the exact amount of support you prefer for your head and neck, shoulders and lumbar area. The UC 550-L is available in four standard fabrics including three In-Stock colors available for immediate shipment. 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.

Effective October 2018, an FDA approved moisture barrier has been added to UC chair boxes. The moisture barrier additive is meant to withstand humid storage conditions that often lead to carton collapse and damage to lift recliners.
The moisture resistant carton is not waterproof and should not be subject to the outdoor elements.


  • Large Size

    UltraComfort lift chairs are available in a few sizes to adequately cater to a range of people in all different shapes and sizes. This chair is for our big and tall customers. Users of 5'11"- 6'2" in height can comfortably sit in the chair and it has a max weight capacity of up to 375 lbs.

  • Pocketed Coil Seat Construction

    The UC550-L lift chair from UltraComfort has designed a very comfortable seat with plush padding and pocketed coils. This creates a seat that will cater to your body and give you the support your body needs no matter what position you are sitting in.

  • Infinity Recline Positions

    There are 4 basic positions that you are able to choose from and then customize to better suit your personal preferences. These positions are “TV Watching”, “Sleep”, “Trendelenburg”, and “Zero Gravity”. Once you are in one of these positions simply make the adjustments you want and reprogram the button to save your changes to that position. Very simple and very easy.

  • Power Lift Mechanism

    Simply hold the lift button down and the seat will raise up so you can easily get in and out of the chair without putting any un due stress on your joints. The entire motion is smooth and motorized and is backed up by a backup battery feature.

  • Back Up Battery Feature

    There is a backup battery feature that will raise the chair up from the reclined position should the power go out. Two 9V batteries provide enough power to raise the chair up so you can get up. It is recommended that you change the batteries after this happens to ensure it has enough power should it need to be used again.

  • Massage and Heat Upgrade Available

    Upgrade your massage chair with massage and heat therapy capabilities to maximize the overall relief this chair can provide. Heat therapy is a great way to help loosen up tension throughout your back and can have a significant effect on back pain.

  • Three Pillow Back

    The backrest provides a three pillow waterfall design that is filled with plenty of plush cushioning so you can sit comfortably. This design ensures you have adequate support from the bottom of your back all the way to the top.

Intuitive Remote

  • Takes you through the motions of a StellarComfort chair as you glide into your comfort zone. When you are finished relaxing, the “Lift” button will place you in the ideal position to get out of your recliner without unneeded stress on your joints.
