You will need to find the narrowest width in your house that your chair will have to fit through. For most, this will be a doorway, but it could also be space between the wall and a table, a tight corner in your bathroom, or any other number of possibilities.
Think of your daily routine and map out a route through your home or office. This will help you determine your needs. Then, measure the tightest spaces with a tape measure. Please check the narrowest necessary width on the search so that Used Wheelchairs USA can provide you with a power wheelchair that can take you everywhere.
