I would suggest talking with a doctor. They should be able to help you identify what type of wheelchair you need and then point you in the right direction.

Do you have a social worker? Are you in a disability payments application process?

Sometimes they have wheelchair programs or discounts. Worth asking cuz wheelchair can come out expensive and often isn’t insured.

Wish I had advice for you but this is one of those threads im going to keep open as I would like to have something in my brain for if I ever am trying to figure this out.
