How safe are lift chairs for seniors living alone?

I wonder how a senior can control his balance after the push that the chair makes? I mean, imagine an old who has different conditions (which is not something rare and surprising) uses these types of chairs. Suddenly, he feels terrible and needs to be in the bathroom. So, he has to stand up, but when he does, he gets dizzy. I think this is a super common thing that could happen to all seniors, feeling dizzy and the urge to go to the bathroom. This push that the lift chairs give to the seniors is not safe. A senior who needs help standing up, it’s not a weird thing to expect him to have other conditions. I prefer handles and walking canes; in fact, I find them more safe and secure than a lift chair.
