Can the whole thing be reversed so the cup holders are on the left side and the vertical "pole" is also on the left? A friend needs it on the left since he's in a wheelchair and his right side does not function (stroke) .

Yes, the manufacturer has confirmed you can have the pole on the left or right. It would be considered a special order item that we would need to send a quote to you for. One of our customer service team members will be reaching out to you shortly
