wheelchair for my father

Taranpreet Kaur Maini

Hi,
My father has jus come to London.he has got rheumatoid arthritis coz of which his joints r distorted.he cant bend his knees and his hands distorted too. I just bought a wheelchair for all terrains for him to b able to show him around.
The problem we are facing is that as he cant fold his legs properly his feet is touching ground nd he has to put in extra effort to keep both legs on the footrest..
Can you please suggest some way so that he can jus keep his legs relaxed.. Some extension or nything like that?
Regards,
Taran
