How safe are lift chairs for seniors living alone?

For seniors who live independently, lift chairs can be a game-changer. My family and I had to hospitalize my 93-year-old grandfather after he suffered a fall as he tried to stand up from a tall chair. This event, unfortunately, led to him passing away in the hospital since his body was too fragile.
Suppose a senior can walk around the house without someone’s assistance. In that case, it would be a great idea to help them stand up more effortlessly with a lift chair. There’s nothing to worry about as long as they know how to operate the chair. It’s the reason why we got one for my grandmother last summer.
