How safe are lift chairs for seniors living alone?

Stairlifts are principally considered mobility aids, installed for security. Some of their salient features are:
• Safety straps
• Press & Hold Function
• Fail-safe over speed governor
• Security cut-off sensor surfaces
• Substitute power
• The Option to remotely call for the motorized chair
• Rotating seats

The safety straps of stairlifts enable users to secure themselves to the chair, protecting them in case of abrupt braking or malfunction. Plus, it does away with sudden slipping off the seat while the elderly are midway through the stairs. These lifts are equipped with a press and hold operation control that facilitates moving in the direction the user desires. If you let go of the arrow button on this control panel, the stairlift stops at any time. Ordinarily, when paused, the stairlift will not resume for some seconds, which is another safety option deterring jerking motions.
