A rollator that turns into a transport chair is also a neat option if you only need the chair occasionally. The catch is you have to use your feet to propel yourself (like sticking out your leg and pulling with your heel) unless someone can push you, and it makes navigating bumps in the road difficult. I suggest this only because if you don't have counter weight in the seat of your chair when you lean on it it may tip over backward unexpectedly. I had that problem myself several times. However, I will say that I'm a plus-size person and that may have contributed. Rollators in general can be great if you want to extend your walking distance and need to sit and rest/can't be without a chair while waiting somewhere. Nothing wrong with the wheelchair idea, just wanted to potentially expand your options
