I can see the use of this for neurological disease, but far and away the most common reason for a stairlift is frailty (or sarcopenia, to be more precise) along with other musculoskeletal conditions like osteoarthritis. Generally in sarcopenia you lose much more quadriceps strength, such that you find it difficult to stand up out of a chair, which is precisely the motion of how this is propelled. I'd therefore find this difficult to justify.

Secondly, stairlifts work because they are retrofitted into people's homes. This would require quite considerable changes to fit, and possibly loss of an upstairs room to make it work.

I agree with you about the target customer group.

It looks like it would only take up a corner of a room though.

Sure, but its the corner of two rooms on two floors. Depending on what your house looks like, that's quite an undertaking to fit, it's destructive to the house, and doesn't replace your need for stairs.
