This came off a tilite Aero Z Wheelchair. it has the extension tubes to make it longer/higher.
Of you look at the last picture, the small pins that are used to Lock the backrest when it's up or folded down is missing, so it will not Lock up or down. It was being used as is.
Because of that is selling it "as is".
It will come as shown only.
It is used and has regular use wear. See the pictures for the exact condition. Thanks for looking.
