If you have a relative or you yourself are handicapped, you are well aware how hard it is to get to other levels of a building other than the main for if an elevator or ramp is not available. Wheel chair stair lifts not only help people in wheel chairs up stairs but also to upper levels of a building such as a church or a museum.
Lifts for special chairs are not inexpensive. Many homes can have a handy chair installed that the disabled person can sit on to get to the higher level, but unless there is another wheelchair at the higher level or someone to take the wheelchair up the stairs, its a problem. However if the person can still walk and is just not able to maneuver up stairs, its not a big problem.
Wheel chair stair lifts are especially handy in parks that may have several levels and people who have a hard time walking distances can use these devices to get to the various levels. This makes the park experience more enjoyable.
Buses also benefit from these devices. People can use these to get around town or on tours. This makes a vacation more accessible for the disabled that do not want to drive their own vehicle. It also makes the trip more enjoyable for the people who accompany the disabled person.
Getting around with a wheelchair can be a major production but wheel chair stair lifts help to relate the hassled that many handicapped people encounter.
