Transport chairs are also called "Companion Chairs" because they have smaller caster wheels and your "companion" will push from behind. Some riders can scoot the chair with their feet to maneuver around the home, we call that self-propelling. if you plan on self-propelling be sure to check the seat-to-floor height and make sure your feet will be on the ground. Regardless, these are the chairs of choice for taking someone out shopping, dinner, doctor's office, etc. They all fold and most have a fold-down back that makes for easy storage and will fit in any automobile trunk.
