Having looked at the prospect of installing Kuna stairlifts, you need to make sure that you consider the next big step, paying up for the service. You could actually choose to either have the stair lifts on a lease or buy them altogether. These are options that would work well for you depending on what your financial situation currently is. If you are comfortable with making a full purchase, you can go right ahead with it. On the other hand, if this is a temporary arrangement, you will be better off getting the stair lift on a lease agreement with the company that is installing them for you. Either of these options carries with it different financial obligations, so make sure you plan accordingly.
