Depending on how your staircase is configured you will need either a straight stairlift or a custom curved stairlift.  While a straight stairlift is a very straightforward application, staircases with turns have multiple options as far as stairlift application.  The type of turn or turns on your staircase and the ability of the end-user to transfer or walk will determine the best option for a stairlift.  As an example, if the staircase has a 90-degree turn in it with a flat landing in the middle, you could either install a continuous custom curved stairlift or install two straight stairlifts and transfer on the middle landing.  The advantage of the curved lift obviously is no need to transfer in the middle, but the two, straight lift option is typically half the cost of a custom curved stairlift.

All of our modern stairlifts run off batteries so there is never a risk of the stairlift not running during a power failure in the home.

This question is answered based on the abilities and budget of the end-user. If the landing in the middle of the two flights is flat often two individual stairlifts can be used to keep costs down. On most flat landings it is as simple as the client riding up the first. Flight, swiveling the stairlift chair, standing up and pivoting and then sitting on the other. For more complex flights or for people whose disabilities may be too involved or complex the custom stairlift is a better option. i.e, someone with M.S. or Parkinson’s would probably benefit from doing the custom unit to avoid the need for a middle transfer, while someone who can typically walk on a horizontal surface, but has trouble with steps could easily use the two stairlift option.
