Our lightest weight rollator is the Drive Nitro 3-Wheel Rollator. At only 12 lbs, the Nitro 3-Wheel rollator is excellent for indoors and outdoors use. With large wheels and ergonomic hand grips, it is an excellent tool to restore balance to the user. It comes equipped with a large storage bag. However, because it is not a 4-wheel rollator, it is not equipped with a seat.
