Stair lifts are a special type of mobility lifting aid that is used to allow safe and independent use of the stairs by people who, because of mobility related problems and diseases, probably would not otherwise be able to safely climb or descend the steps.

A stair lift is usually installed directly to the steps of the stairs and consists of a reinforced metal track and a car that is sent up and down the track. The car usually consists of a chair, which the occupant rides in, and also houses the electric motor that operates the lift. Some cars also contain the battery, but of course this would only apply to battery powered stair lifts.

A battery powered stair lift can be a great choice if you live in areas that have frequent power disruptions. There are many areas where it is common to have a black out, and if your lift is battery powered, you will never be left stranded at the top or bottom of the steps.

There is a little bit of extra maintenance required for a battery powered lift and the battery will also have to be periodically checked and replaced. A regular AC powered stair lift will usually cost a little bit less, but of course will not work if the power goes out.

Most stair lifts are able to support around 250 to 350 pounds. The weight capacity varies slightly by model and sometimes the distance that a stair lift spans can affect the weight capacity of the unit.

A stair lift is a great way to stay safe while using the stairs and they can also be used to carry things up and down the steps. This is one reason that it is a good idea to always add at least an extra 20% of your weight onto your weight requirement. This will ensure that you will not run into problems if you decide to transport something with you up the stairs or if you grow a little bit. For example if you weigh two-hundred pounds, then you would want a stair lift that was at least rated for two-hundred and forty pounds.

Those that have a straight stair lift can generally have their lift up and running in only a few hours. Most dealers and manufacturers are fairly quick about shipping the stair lift, and usually the installation can be done in an afternoon. A few of the pieces can be a little bulky and the car unit usually weighs around one-hundred pounds, so it is a good idea to have a helper there with you during the installation.

A stair lift can actively reduce the risk of falls and even death that can result as of a fall down the stairs.
