Renting a stair lift is a viable option of for short period of time. Generally speaking, renting a stair lift for three months or less is cost effective.
Only straight stair lifts are rented. The only exception to this fact is if your stairs have a flat landing at the mid point, and you are willing to consider renting two separate straight stair lifts
This price range includes preparing the lift for your stairs, installing the lift, maintenance of the lift and a warranty.
