Stair lifts are motorized chairs or platforms designed to transport individuals up and down staircases, providing a safe and convenient mobility solution for those with limited mobility, balance issues, or difficulties with stairs. They consist of a track installed along the staircase, on which a carriage with a seat or platform travels. Stair lifts are custom-fitted to the specific dimensions and configuration of a staircase, whether straight or curved. They feature safety sensors, seatbelts, and often swivel seats for easier transfer at the top or bottom. Installing a stair lift can significantly enhance independence and safety within a multi-story home, allowing individuals to access all levels without the risk of falls or the need to relocate. They are a popular and effective alternative to moving or building costly ramps for people struggling with stairs.
