Where Can I Buy Armrest Covers for My Wheelchair?

Anonymous asks, quote:

Hi there! I’ve been using a wheelchair for about half a year now and have a folding, rented wheelchair with non‐removable arm rests (and no current capabilities of buying my own wheel chair) & I’ve been getting some fairly bad pain & redness from where my arms rub against the armrests when I push myself. Do you have any recommendations for a site where I’d be able to buy armrest covers, or any other suggestions? Thanks a bunch!
