It is estimated that more than 30 million Americans have difficulty walking or climbing stairs and this number is likely to increase with the growing aging population. To prevent falls and rule out the hurdle of climbing stairs, you can consider adding a stairlift to the home. A stairlift is in fact a chair on rails that can carry the user up and down the staircase, whether straight or curved. Operated using a battery or home electrical system, the stair lift has a back rest, two arms and foot rest. It travels up and down a rail installed on the side of the staircase. The rail can be installed on both narrow and wide stairways provided the stair tread is strong, because the railing on which the stair lift moves is bolted to this stair tread. A stairlift gives mobility impaired and elderly people a sense of independence and also helps them to move around in every part of the house comfortably. It allows access to the top floors of the home and allows them to stay in their own homes as they age, rather than move out to a more accessible house.
