For many elderly and/or disabled people, the stairs that once were so easy to climb may suddenly become a major obstacle in daily life. As a result, these individuals spend most of their times confined to the ground floor of their homes, with the upper levels practically unreachable. According to a study by the University of California Disability Statistics Center, more than 60% of the 1.6 million wheelchairs users in America face daily problems in getting around the house. Often times, the relatives of these people will simply advise solving the problem by relocating to a bungalow or care home. However, the logistical and emotional impacts of moving one's residence are many times grossly underestimated. To those affected, having to leave one's trusted home will often feel like giving up, which could in the longer term lead to depression and a general sense of failure. Luckily, there is an answer: a stair lift.

A stair lift, sometimes also referred to as a chair lift is made up of a high-quality wall-mounted rail with a comfortable, mechanic chair attached. The chair slides up and down the rail through a rack-and-pinion system, transporting the seated individual up and down the stairs with very little effort. The device was originally invented by C.C. Crispen during a high incidence of polio in the 1920s, to help his wheel chaired friend in climbing the stairs of his home. In recent years, the device then known as the ?inclin-ator? has underwent major steps in development. Stair lifts come in different varieties, able to tackle both straight stairways and curved stairs. Additionally, one may encounter models for use outside and models which feature a large platform suitable for parking a wheelchair.

If lack of mobility starts limiting your action radius to the ground floor of your house, you may want to think about having a stair lift installed. In these days, stair lifts no longer have to be those bland industrial-like machines that contrast so strongly with your home interior. You will find that there is a wide variety of seat models and cover materials available, to make sure your stair lift fits neatly into the trusted interior of your home. As for current, stair lifts come in both AC (alternating current) and DC (direct current) variations. AC-powered lifts are connected directly to the mains power supply, while DC-powered lifts utilize a special kind of rechargeable battery pack. DC-powered lifts are generally more expensive, but they have several critical advantages. The most important advantage of a DC-powered lift over an AC-powered lift is safety; in case of a power blackout, a DC-powered lift will continue to operate. You should remember that short-circuits are a very common cause of fire; in such a case, an AC-powered lift can not transport you down to safety. When planning to buy a stair lift, don't forget to take the following factors in due consideration:

* Glide: the glide-factor will determine the overall smoothness of the ride.

* Power supply: a DC powered lift offers better safety and a generally smoother ride.

* Control: for those suffering from arthritis, a joystick-control is generally regarded as more convenient than a button control.

* A swivel chair will allow you to exit and enter the lift without taking awkward steps.

Considering the cost, a stair lift is not likely to be be light on your wallet. However, because of recent price drops, prices have fallen into a range that is acceptable to most people with a normal income. In the end, the price will mostly be determined by your personal needs and the design of your staircase. Curved stair lifts are custom-made and are therefore significantly more expensive to manufacture and install. For those that can not pay up front, stair lifts are also available for rent. You could also consider consulting your retailer for special financing plans. Always consult a local retailer and have your home evaluated before investing in a stair lift.
