As a brief intro I suppose ..... unlike some of you, I am a more recent lower limb amputee (below left knee) so am a babe in the woods as it were to a great bunch of things regards mobility aids, wheel chairs etc.
One thing I have already taken on board however, is that its more than obvious that in the majority of cases the designers of a lot of the aids that are about have most probably never had anything to do with actually being physically impaired or actually sitting for a prolonged period, if any in of them.
As a past engineer, fortunately or otherwise, I have a really inquisitive perspective on things generally.
What I am looking for I suppose, is to gain a better insight into things generally. Learn a whole lot more of the "why" vs the "why not" re mobility aids and chairs in particular.
Cheers
