Mom, who is 88, recently broke her tibia in a fall and would like to have a rollator that has hand brakes. The one she has now has brakes if you sit on the seat, but then you can not move the thing without standing up. The medical equipment store wants to sell her a rollator that you can make more narrow in order to get through any sized door without losing the stability, but it costs $500!! Not gonna' happen!
You can ask her doctor to write a script for a dollar as Durable Medical ewuipment, but I'm not sure if they will pay for a specific model.
Check Costco!
