I have been the stairlift industry for almost 20 years and there is one thing that I have learned the hardway. A new stairlift model is not necessarily better. What I mean by this is that I have found that stairlift models that have been out in the marketplace for at least two years tend to be more reliable than a new stairlift model.
1. The stair glide user can not bear weight on their feet and thereby make transferring to the seat of stair glides not a safe process.
2. The stairway is too narrow to allow for the stair glide user to sit on the seat of the stair lift and not hit their knees on the adjacent wall.
