The Dualer power wheelchair by Merits can operate in front and rear drive depending on the user's needs. To switch from front to rear drive, rotate the seat of the chair 180 degrees and lock it into place. A plush seat with a low height of 22" and large 10" foam-filled tires allow for added stability while in motion. Enjoy a smooth ride indoors or outdoors with the Dualer power wheelchair's large caster wheels and removable anti-tippers. The chair's 19.6" turning radius and compact frame allow you to maneuver through narrow doorways and in tight spaces easily.
