A stairlift is a mechanical device designed to help individuals move up and down stairs safely and easily. It consists of a chair or platform that travels along a rail installed on the staircase. Stairlifts are particularly beneficial for people with mobility challenges, such as the elderly or those recovering from surgery. These devices can be customized to fit various stair types, including straight and curved stairs. Stairlifts are powered by electricity and often come with features like safety sensors, remote controls, and swivel seats for easy access. They provide a practical solution for maintaining independence in multi-level homes.
