Your rollator should be fairly easy to maneuver – if you're having big issues turning corners, you might have a faulty rollator on your hands – but some are easier than others. As a rule, three-wheeled rollators are easier to maneuver than four-wheeled models, and small-wheeled rollators are easier to maneuver than larger-wheeled models. The catch is that three-wheeled rollators aren't as stable as four-wheeled models and rarely have seats, and small-wheeled rollators don't handle rough surfaces very well.
