A lift chair helps only when the seat fits the person, the room gives it space to recline and rise, and the power source is safe. Most problems come from measuring the chair in the store and forgetting the room at home.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Measure the person
Measure your parent's standing height and their seated height from the floor to the top of the thigh, and note their weight. Check the weight rating on the chair's label or product page, and do not choose a chair that is close to the limit. Look at the seat depth and seat height in the listing. A chair that is too deep leaves the back of the knees unsupported, and a chair that is too low makes getting up harder.
Measure the room
A lift chair needs space behind it to recline and space in front to rise and tilt forward. Measure from the wall to the front of the chair's footprint, and check the manual or listing for the recommended clearance from the wall. Measure the walkway width as well, since a chair that blocks the path to the bathroom creates a hazard of its own.
Check the outlet and cord
Find the nearest wall outlet and confirm the cord can reach it without running under a rug or across the walkway. Many manufacturers say not to use an extension cord with a power recliner. Check the manual for that rule before deciding where the chair goes, since a chair placed for the view may sit too far from an outlet.
The sit-test
If you can, have your parent sit in a chair of similar height and watch them get up and down. Ask whether the armrests help, whether their feet reach the floor, and whether the seat feels right. A store test is not a substitute for the real chair in the real room, but it catches the most common mistakes.
What to do tonight
Measure your parent's seated height and the room's wall clearance, and photograph the outlet and the planned spot. Compare those numbers with the listing of any chair you are considering. Keep the measurements in one note so they travel with you to the store or the phone call.
What to leave with the doctor
Bring a short list of what is hard for your parent now, including getting up from low seats, standing balance, and knee or hip discomfort. Ask whether the lifting motion and the chair's seat height suit those needs, and whether your parent's weight and balance fit the chair's rating. The answer belongs to the doctor or a therapist, and it should come before the purchase.
