I have a son in a wheelchair. I've made him simple bags, but you 1st need the measurements of the wheelchair. As someone suggested you can also make one for the side. That would be smaller and fit to the inside of the chair. We used this for valuables, money, keys, pencils or pens, etc. so that it wasn't available to everyone. Someone helped him get things out of the back bag. You do need to measure to know the width for all bags.
