A lift chair is her own chair, and the goal is to keep it that way. The parts that wear are the motor, the cord, the frame, and the fabric. A short routine, kept up by whoever lives with her or helps her, catches most problems before they become a stuck chair.

Each day
Look at the chair once a day. Check that the cord is not pinched, frayed, or stretched across a walkway, and that the plug sits firmly in its outlet. Make sure nothing is stored under or behind the chair that could block the mechanism. Notice whether the chair raises and lowers as it usually does.
Each month
Pick one day a month for a slower check. Raise and lower the chair with nothing on the seat, and listen for grinding, clicking, or a pause partway through the movement. Watch whether it tilts evenly. Check the armrests and the hinge points for looseness. Look at the seat and back fabric for tears that could catch a hand or a sleeve. If the chair runs on a rechargeable battery, check the charging cord and follow the maker's guide for charging.
When to stop using it
Stop using the chair and call the seller, installer, or maker if it stalls partway, makes a burning smell, sparks, lowers on its own, or shows a cracked frame or exposed wiring. Do not open the motor housing or change internal settings yourself. Keep the chair unplugged until someone qualified has looked at it.
Who keeps the paper
Keep the manual, the receipt, and the warranty card in one place. Write down the model number and the phone number for service. If you bought the chair from a shop that delivered and set it up, ask what they cover and for how long. Those papers decide who answers when something fails.
When her getting up changes
If she starts needing more help to rise from the chair, or if she uses it less than she did, tell her care team and note the change. Her chair is one part of how the house supports her, and a change in how she uses it is worth a conversation. For the wider set of questions this desk covers, the Keep Her Home page explains the approach.
