3-Wheeled Rollators do not have seats like the 4-wheel style. They are typically used by people with balance issues, but are fully capable of supporting users weighing up to 300-lbs. The 3-wheeled rollator's advantage is greater maneuverability. With only a single front wheel, passing through doorways or a tight path is easy.
For stability and safety reasons, 3-wheel rollators have a slightly wider footprint, usually around 25" overall width.
These 3 wheel rollators collapse inward to fold. The rear wheels come together so when folded the 3 wheel rollator is only about
10" wide. Easily fits into auto trunk or back seat.
