Hi, My wife can walk short distances and can go up and down steps when needed, but uses a wheelchair for any longer distances. Right now, she has a cheap standard wheelchair. We are headed to Italy in a week, where we will visit Rome, Florence, and Venice. We want to get her a better quality wheelchair before our trip. I was looking at the Karman Ergo line, but then found some information on the Roughrider Whirlwind, which looks good for rough terrain. This one: https://whirlwindwheelchair.org/product/roughrider/ For the Karman's, maybe something like this: https://www.karmanhealthcare.com/product/s-ergo-305/ Any thoughts on the best chair to handle the cobblestone streets we will encounter?
